Can the biogas digester filler, the waste liquid of the biogas digester, be used as fertilizer?

household biogas digester filler; Eighty percent of the volume of the pond is filled at one time, and the dry matter content is 100 percent to 6 to 8, and the details are added.

How big is a digester? What is the process?

The biogas digester is mainly the strain and raw materials and water.

The strain is the sludge in the old toilet or gutter;

The hydraulic tank charge accounts for 90% of the volume of the main pool;

Generally, the strain is put in 30%, 70% is raw materials, and 40% of the 70% raw materials are water (assuming that the raw materials are pig and cow dung).

Biogas residue is a semi-solid matter left over after the fermentation of biogas, and biogas residue is very versatile.

First, biogas residue is rich in organic matter, humus, micronutrients, a variety of amino acids, enzymes and beneficial microorganisms. The texture is loose, the moisture retention performance is good, and the pH is moderate, which can play a good role in improving the soil.

Second, biogas residue contains nitrogen, phosphorus, potassium and other elements, which can meet the needs of crop growth.

Third, the biogas residue still contains more biogas slurry, and its solid matter content is below 20, and some of the undecomposed raw materials and new microbial bacteria will continue to ferment when applied to farmland and release fertilizer. Therefore, in the process of comprehensive utilization, biogas residue has two functions: quick-acting and delay-acting, which can be used as base fertilizer and top dressing, which can not only reduce the amount of chemical fertilizer and pesticide application, reduce costs, but also effectively improve the yield and quality of crops. Biogas residue is mainly used as a base fertilizer for crop production or seedling production, and can also be used for the production of edible fungi, fish farming, earthworm farming, etc.

As a high-quality organic liquid fertilizer, biogas slurry is used for extra-root application, first of all, its nutrients can be directly absorbed by crops and participate in photosynthesis, thereby increasing yield and improving quality. In addition, foliar spraying of biogas slurry on plants can play a role in the prevention and control of some pests and diseases, reduce the use of chemicals, and is conducive to the production of pollution-free agricultural products.

Biogas slurry contains various amino acids, vitamins, proteins, gibberellins, auxins, sugars, nucleic acids and antibiotics. For example, gibberellin allows seeds to germinate early; Some nucleic acids and monosaccharides can enhance the drought resistance of crops; Some free amino acids can enhance the frost resistance of crops; Some antibiotics can control crop pests and diseases; A variety of amino acids and trace elements are added to rice feed to promote the increase of livestock and poultry yield. Biogas slurry is mainly used for seed soaking, page spraying, mixing nutrient bowl soil and flower and fruit promoting, cultivating mother liquor, formula drip irrigation, fish farming, pig raising, chicken raising, cattle raising, duck raising, sheep raising and flower breeding.

Biogas slurry can be directly applied to cultivated land as base fertilizer, and can only be used after standing treatment as top dressing. Independent of its concentration.

The direct discharge of the waste liquid of the biogas digester is not up to standard! So the premise of building a biogas digester is to build a "sewage treatment plant" to treat the digester waste!

At the end of the day......

It's a pit!

Summary. Hello dear, the biogas tank can be put into the septic tank dissolving agent. Biogas and septic tank can be used at the same time The process of septic tank degradation will produce biogas, which can be led out as gas, and the product of septic tank degradation can be used as high-quality natural fertilizer.

The difference is that the digester is closed; Septic tanks do not need to be airtight.

Hello dear, the biogas tank can be put into the septic tank dissolving agent.

The biogas digester is closed; Septic tanks do not need to be airtight.

It is a combustible gas produced by organic substances in an anaerobic environment under certain temperature, humidity and pH conditions through microbial fermentation. Since this gas is first found in swamps, lakes, ponds, people call it biogas. Biogas contains multiple gases, the main component of which is methane (CH4).

The process by which biogas bacteria decompose organic matter to produce biogas is called biogas fermentation. According to the role of various types of bacteria in the biogas fermentation process, biogas bacteria can be divided into two categories. The first type of bacteria is called decomposers, which are used to break down complex organic matter into simple organic matter and carbon dioxide (CO2).

Among them, there are those who specialize in breaking down cellulose, called fibrolytic bacteria; There are those that specialize in decomposing proteins, which are called proteolytic bacteria; There are those that specialize in decomposing fat, called lipolytic bacteria; The second type of bacteria is called methane-containing bacteria, commonly called methanognes, which oxidizes or reduces simple organic matter and carbon dioxide to methane. Therefore, the process of turning organic matter into biogas is like the two processes of producing a product in a factory: first, it decomposes bacteria and processes complex organic matter such as manure, straw, and weeds into semi-finished products - compounds with simple structures; Then there is the processing of simple compounds into products under the action of methane bacteria - that is, methane is generated.

Is the biogas produced toxic.

Pro, the biogas produced is toxic. Hydrogen sulfide, ammonia, and phosphine produced during the fermentation of toxic biogas are all toxic gases. Hydrogen sulfide has the smell of rotten eggs, a nerve agent, mainly affecting the central nervous system and respiratory system, and can also be accompanied by damage to multiple organs such as the heart.

Ammonia is also a nerve agent, ammonia poisoning can cause laryngeal edema, glottis stenosis and respiratory mucosal detachment and other symptoms, starvation can cause tracheal rot and jujube blockage, causing suffocation. Phosphine is a highly toxic substance, which can be fatal when exposed to 409-846 milligrams of cubic meters. Although carbon dioxide and methane are non-toxic gases, when the concentration is high, it can also make the human body lack oxygen, inhibit and paralyze the respiratory center, and lead to asphyxiation poisoning.

You can use biogas liquid for fermentation, and then mix it with crops, which is better fertilizer.
