How to make fertilizer from digestate residue? 10. How to make fertilizer from biogas residue?

There are three ways to do this:

1. Make biogas humic acid fertilizer. The biogas residue taken out of the biogas digester is piled together with organic garbage or soil, a layer of garbage (or soil) is added to a layer of 20 30 cm thick biogas residue, piled into a large round table-shaped manure pile, and then the surface is covered with some soil and patted, and the pile is piled up for 15 to 20 days to become biogas manure. The fertilizer is suitable for base fertilizer, and the application rate is 1000 kg per mu.

2. Biogas residue and superphosphate pile. After composting biogas residue and superphosphate, it can increase phosphorus activity and significantly improve fertilizer efficiency. Generally, 50% 70% wet biogas residue with water content per 100 kg is mixed evenly with 5 kg of superphosphate, and the pile is decomposed for 7 days, which can improve the activity of phosphorus and play a significant role in increasing yield.

Specific method: first put a layer of 20 30 cm thick biogas residue and phosphate rock powder mixture, then put a layer of organic fertilizer (thickness of 30 40 cm), and then put biogas residue, organic fertilizer, thus forming a manure pile, put the soil on the surface of the compost pile and compact. In about 1 month, the compost is made into biogas decay phosphorus fertilizer, which has a significant effect on the yield of phosphorus-deficient soil.

500 1000 kg per mu can increase grain yield by more than 13%, or increase vegetable income by more than 15%.

3. Biogas residue and ammonium bicarbonate pile. Because biogas manure contains a certain amount of humic acid, it can react chemically with ammonium bicarbonate to form ammonium humate, increase the activity of humus, and improve fertilizer efficiency. When the water content of the biogas residue drops to about 60%, it can be piled into a pile of about 1 meter, and countless small holes are pierced on the pile with wooden sticks, and then 4 5 kg of ammonium bicarbonate is added to every 100 kg of biogas residue, mixed evenly, sealed with thin mud after the pile, and then covered tightly with plastic film, and fully piled for 5 7 days.

The fertilizer can be used as base fertilizer and top dressing at seedling stage. When topdressing at the seedling stage, the dosage per mu is 250 500 kg.

Dryers and mixers are required to make organic or compound fertilizer. There is nothing wrong with using the digestate as fertilizer without any treatment.

Biogas residue is a type of organic fertilizer.

Organic fertilizers can be used instead of chemical fertilizers. For 5,000 years, there were no chemical fertilizers in ancient China, and the soil has always remained fertile.

Long-term use of organic fertilizer, soil organic matter is very much, plants need a lot of minerals, and relatively complete, in addition to nitrogen, phosphorus, potassium, but also contains calcium, magnesium, sulfur, zinc, boron, manganese, molybdenum, copper, iron. All the minerals needed by plants can be found and contained in farmhouse organic fertilizers. High-quality organic fertilizers are full-price fertilizers, which have a lot of heat advantages than ordinary fertilizers.

Therefore, organic fertilizer can be used instead of chemical fertilizer.

Analyze their characteristics:

Chemical fertilizer: the advantage is that the nutrients are high, the effect is fast, etc., it is a fast-acting fertilizer, the disadvantage is that the fertilizer effect lasts for a relatively short time, and the nutrients are relatively single.

Organic fertilizer: the nutrients are relatively comprehensive, the fertilizer efficiency is longer, contains a variety of trace elements, enhances the disease resistance of crops, increases the yield, and can improve the organic matter of the soil.

Finally, it can be seen that the application of chemical fertilizer with organic fertilizer is ideal for the growth of crops, which achieves the effect of learning from each other's strengths and complementing each other's weaknesses, and also ensures the nutrient demand for each growth cycle of crops.

For example, the combination of chemical fertilizer and organic fertilizer can also adjust the soil pH, increase soil nutrients, improve fertilizer utilization rate, and provide a long-term fertility of crops.

Most fertilizers are fast-acting synthetic fertilizers, while fermented digestate is long-acting biofertilizers.

Under the premise of simply pursuing yield, the fertilizer efficiency of chemical fertilizer is significantly higher than that of biogas residue, but it will cause problems such as soil nutrient imbalance, compaction, and crop quality decline. However, if biogas residue is used instead of chemical fertilizer, although it has obvious effects in improving soil and crop quality, it has not been effective in terms of yield. Therefore, in order to take into account the yield and quality of crops, organic fertilizers such as biogas residue and chemical fertilizers are usually used in combination in agricultural production.

Absolutely, natural full price organic fertilizer.

The methods for cleaning the manure residue in the biogas digester are:

1. Biogas digester pump.

A kind of biogas digester pump, there is a circular cylinder, the upper side of the cylinder has a liquid outlet, the lower end of the cylinder is connected with a one-way opening bottom valve, the upper mouth of the cylinder is equipped with an upper cover, the upper part of the upper cover has a protruding ring, a sealing ring is installed in the annular cavity belt between the inner circle of the protruding ring and the outer periphery of the tie rod, and the upper part of the protruding ring is connected and gland through threading.

A one-way piston is installed in the cylinder, and the piston is connected to one end of the pull rod, and the other end of the pull rod stretches out outside the upper mouth of the cylinder through the center hole of the upper cover and is connected with a handle. The pump is installed in the biogas digester to solve the problem of difficult discharge of the biogas digester, avoid the crusting of the upper layer of the biogas digester, and improve the gas production per unit time.

2. Biogas slag pumping truck.

The utility model discloses a biogas slag pumping truck, which is mainly composed of a frame, a diesel engine, an air pump, a transport tank, etc.; The main point of the utility model is that: the upper part of the transport tank is respectively provided with an air extraction pipe, a feed pipe, and a discharge valve is arranged below its rear end face.

Because the utility model discloses a above-mentioned technical scheme, can reduce the cost by nearly half, and greatly improved the removal rate of biogas residue, biogas slurry, has the advantages of convenience, speed, safety, health simultaneously.

Precautions. 1. The person who evolved the septic tank must wear a gas mask and a gas suit, as well as a safety belt, which should be tied with a rope that can bear a weight of more than 100 kilograms, and the other end of the rope must be tied to a ladder exposed outside the septic tank.

2. There must be two to three people on the septic tank to pay attention to the situation in the septic tank at any time, and if the situation below is not right, the staff who clean the septic tank will be pulled up.

3. The septic tank generally has three manhole covers, and each manhole cover has two small holes, and we have to open the small holes on each manhole cover every half an hour or an hour.

4. Then use the iron hook to open the manhole cover, and after opening, rinse each wellhead with fire water for about half an hour. This reduces the amount of biogas in the septic tank a lot.

5. Then use a bamboo pole with a length of about 5 meters to insert it into the septic tank to get the depth of the dirt and sewage in the septic tank.

6. If the depth of the septic tank is more than one meter, we have to use a bamboo ladder or other ladder about 1 meter deeper than the septic tank to put it into the septic tank.

Summary. The slag removal of the biogas digester can be carried out in combination with the needs of planting fertilizer and the agricultural slack season, generally every 3 months, and about one year for a large cleaning. Usually Xiaoqing takes out about 100 kg of sediment; Daqing took out about 1,000 kilograms of sediment, and even completely refueled.

The slag removal of the biogas digester can be combined with the needs of planting fertilizer and the mountain cherry blossom festival during the agricultural slack, and it can be cleaned once every 3 months, and it will be cleaned about a year or so. Usually Xiaoqing takes out about 100 kg of sediment; Daqing took out about 1,000 kilograms of sediment, and even completely refueled.

Under the premise of normal production of biogas, within a certain period of time, it is necessary to hold the same amount of fermentation raw materials, domestic sewage and the same amount of biogas slurry and biogas residue, and the appropriate amount of plant ash can be added, or the appropriate amount of clarified lime water and fermentation broth should be mixed evenly to adjust.

Human, livestock and poultry manure and crushed crop straw are better used after decomposing and weekly.

How to convert manure from a pig farm digester to clean water.

Please wait a moment while the information is sorted out for you.

Water flushes out the manure. There are three ways to clean the manure: one is the water flushing manure cleaning mode, the second is the blister manure method, and the third is the dry manure cleaning method, and the water flushing is the auxiliary mode.

The manure in the biogas digester of the pig farm is turned into clean water, and there is no chemical manure in the biogas digester from water.

In pig farms with water flushing, the discharge capacity of each pig is about 40 l d. In pig farms with dry cleaning or manure-based, the collection rate of pig manure and urine of grinding wheels is more than 75%, and the sewage discharge volume of each pig is about 10L DO

Microbial septic agents.

The septic tank does not need to be filled with medicine, and the natural fermentation produces biogas, and the manure is turned into water. The most commonly used and most economical solution is sodium hydroxide solution. The second is a special lotion (such as Lan Xiaoyou, Sakura, etc.).

The digester is full, it can't be fermented, and there is no chemical chemical to remove it from clean water.

That can only be partially extracted first.

Sodium hydrochloride solution.

with sodium hydroxide solution.

Or the Blue Star.

How long does it take to pour sodium hydrochloride solution into a digester to melt clean water?

With sodium hydrogen chloride solution in a pack or a bottle?

It depends on how big the digester is.

After pouring in, it has to ferment into water for a week.

The digester should have 3 stands.

If you use the bottle, pour two bottles and pack three packs.

Biogas residue is the residual suspended matter after biogas fermentation, which is composed of partially undecomposed raw materials and new microbial bacteria, which are rich in inorganic nutrients and organic nutrients, and the main uses include fertilizer, preparation of culture soil, artificial substrate and cattle farm bedding.

(1) Used as fertilizer

After being applied to the soil, part of it is absorbed and utilized by crops, and the rest of the nutrients still exist in the soil, and enter the deeper layers of the soil with water to improve soil fertility. Biogas residue contains a large amount of chlorine, phosphorus, potassium and other available nutrients, and is also rich in medium and trace elements, which can promote the growth and development of crops.

Biogas residue also contains a large amount of organic matter and humus, which can improve soil structure, physical and chemical properties, fertilize soil fertility, and biogas residue does not contain nitrate components, which is a high-quality pollution-free, green and organic fertilizer for the production of organic agricultural products. Most of the domestic biogas residue is used as base fertilizer to produce vegetables, fruits and field crops, which has good economic and ecological environmental benefits.

(2) Preparation of nutrient soil

It is mixed with fertile field soil in a ratio of 1 3 and can be used as nutrient soil. The nutrient soil prepared with biogas residue can better prevent and control the harm of wilt, blight and underground pests, and play a role in strengthening seedlings.

(3) Make an artificial substrate

Biogas residue products are not only rich in nutrients, but also loose in texture, moderate in acid and alkali, and are high-quality artificial substrates for the cultivation of edible fungi, which can be used alone or mixed with rice husks and sawdust. Studies have shown that the cultivation of edible fungi with biogas residue artificial substrate can increase the yield by 30% to 50%, and can improve the quality of edible fungi. The high-quality biogas residue artificial seedling substrate partially or even completely replaces the grass ash, and the seedling raising effect is better than that of the conventional artificial seedling substrate.

(4) Cattle farm bedding

In order to provide a comfortable environment for dairy cows, farmers often spread sand, sawdust, etc. on the ground to form a bed, and make a bed with biogas residue, which can increase comfort and save costs. In production, biogas residue is more used for the paving of sports field floors.

After human, livestock, poultry manure and crop straw are anaerobic to produce biogas, the solid part separated by solid and liquid is commonly known as biogas residue. It is rich in humus-rich organic matter, with a content of 40% 60%, total nitrogen 1% 2%, and contains vitamins, hormones, etc., which can be used as feed, fertilizer and base material for cultivating edible fungi.

(1) Biogas residue is rich in organic matter and humic acid, which can play a role in improving soil.

2) Biogas residue contains nitrogen, phosphorus, potassium and other elements, which can meet the needs of crop growth.

3) The biogas residue still contains more biogas slurry, and its solid matter content is less than 20%, and some of the undecomposed raw materials and new microbial bacteria will continue to ferment and release fertilizer when applied to farmland. Therefore, in the process of comprehensive utilization, biogas residue has two functions: fast-acting and delay-acting.

Biogas residue is mainly used in the production of grain, seedlings, seedlings production of base fertilizer, can also be used for the production of edible fungi, fish farming, eel farming, loach farming, earthworm farming, etc.

Hello, conditions for the production of biomanure.

1. Operation method 1Preparation (1) Biogas residue: Due to the domestic use of dry and wet biogas production methods, the water content of biogas residue is usually about 40%-70%.

2) Excipients: Excipients with a water content of no more than 10% (such as straw powder, rice bran, peanut shell powder, etc.), mainly used to adjust the air permeability of biogas residue during fermentation. (3) Biological fermentation bacteria:

Mix the weighed microbial agent and excipients in a ratio of 1:10 (the purpose is only to expand the volume of the microbial agent and facilitate the uniform sprinkling on the biogas residue), and then weigh the required biological microbial agent and the treated biogas residue at a ratio of 1:10,000 (ten tons per kilogram).

2.Production process (1) If the moisture of the biogas residue is more than 70%, it can be mixed with the auxiliary materials in a weight ratio of 3:1, add 1% of the grinding and grinding quicklime and stir, and then add the expanded volume of the microbial agent to the biogas residue, stir and stack evenly.

2) The moisture content of the stirred fermented product should be controlled at about 60% (the hand is lightly held into a ball, and three or five seams can be split when loosened, at least to ensure that the hand is firmly held and will not drip from between the fingers). (3) Stack the stirred fermented products with a height of about 2m and a length of about 2m. Blind (4) fermentation for 24 48 hours, the temperature can be over 55 or more, and the deodorization effect can be achieved three days after heating.

5) After 15-20 days of stacking and fermentation, it can be used as bio-type organic fertilizer. Biogas manure has good nutritional value, how to make high-quality biogas fertilizer? Precautions in pretreatment of fermentation points: 1. Poor air permeability

In the strict fermentation process, the quality of air permeability directly affects the reproduction of anaerobic bacteria or aerobic bacteria. You can use the jack in the pile, bury the tied straw bundle in the pile, and hold it up with bamboo sticks or wooden sticks at the bottom to increase its air permeability. In strip stacking or vat fermentation, note that the ratio is the weight ratio, not the volume ratio. 2. Moisture:

Fermentation with biological bacteria is about 60% water content (that is, it is held in a ball and can be cracked when loosened). If the water content is too large, the heating time will be faster, but the cooling will also be fast, and the decomposition will not be complete; Only the right amount of water can keep the fermented material at more than 50 degrees. 3. Stir well:

Whether it is stacked in the field or stacked fermentation or tank fermentation, especially when the amount is large, this situation will definitely occur, resulting in uneven temperatures. If the fermentation material cannot be mixed evenly or the bacteria and fermentation materials cannot be fully mixed, the deodorization effect is not ideal, which directly affects the quality of organic fertilizer. 4. The dosage is 100 grams of microbial agent to ferment one ton of biogas residue, and the volume is expanded with 1 kg of straw powder unless otherwise specified.

Biogas manure has good nutritional value, how to make high-quality biogas fertilizer? Solutions to common heating problems in the fermentation process 1, slow fermentation temperature is a water regulation problem, first see whether the moisture is greater than 60%, if so, add considerable auxiliary materials to adjust to 60% and mix well, if less than 40%, add water or fresh manure water to adjust to 60% and mix well; Thank you for your inquiry, we will be happy to answer for you.
