What is food waste biochemical treatment?

Biochemical treatment of food waste refers to the microbial ecological treatment method of garbage generated by hotels and other catering industries, referred to as biochemical treatment and fermentation method, which solves the harm of food waste to the environment through microbial fermentation. Now there are many large-scale food waste treatment equipment on the market that use fermentation to solve the problem, such as the more famous Shaanxi Daming Machinery, the final treatment step of the food waste treatment system they developed is to solve the solid residual waste through the fermentation method.

It is an indispensable carrier for the biochemical treatment of food waste, and an equipment that provides conditions for microorganisms to play a role. For example, the DC kitchen waste biochemical processing machine of Beijing Sunshine Shengjing Company, you can consult what is the food waste biochemical treatment, and the things with use value must be valuable" is wrong, and the value of the commodity is the undifferentiated human labor condensed in the commodity. Use value is the natural attribute of the item, and things with use value are not necessarily valuable, such as the air in nature, air has use value for people and can be breathed, but it is free to use and is not exchanged, so it has no value.

Items with use value are not necessarily valuable, air has use value, is one of the three elements of human survival, but there is no value, that is, it can not be called a commodity, if a person enters the deep mountains and old forests, with bottles and cans filled with fresh air to transport to the polluted city to sell, then the air at this time has value, can be called a commodity.

Valuable things must have use value" is right, use value is the material bearer of value, there is no use value there is no value, commodity value must have use value, because value is reflected through paid exchange, since it can be exchanged, it means that there is use value.

Waste biochemical treatment technology is to use microorganisms in nature to decompose and transform organic substances and degrade organic pollutants. According to whether the microorganisms are aerobic or not, it can be divided into two treatment methods: aerobic and anaerobic fermentation.

Food waste can be used as compost for vegetables, fruits, or flowers.

Here are some guidelines for making fertilizer for your home:

Food waste composting is the process of using microorganisms and small insects in nature to break down organic matter (food waste) in the presence of air and water. The final product is called food waste fertilizer, which is rich in easy-to-use phytonutrients that form part of a healthy soil. It is recommended to buy a bucket and wooden box for composting food waste.

It is best made on the balcony or outdoors. When the food waste compost is fermented, it will have a taste (mainly ammonia and hydrogen sulfide).

Kitchen waste composting mainly has the following conditions: carbon-containing organic matter such as dried leaves, wood chips, paper, peanut shells, melon seed shells, etc. Nitrogen-containing organic matter such as fruit and vegetable waste, coffee grounds, malt powder, etc.

1. Air 2. Appropriate amount of water 3. Treat kitchen waste and turn waste into treasure.

Easy 6 Steps:

1. Separate edible kitchen waste (vegetable peels, fruit peels, a small amount of wasted cooked food) into containers.

2. Collect the dried organic matter (dried leaves, sawdust) in a small container.

3. Take a box or a bucket and drill 4 5 different holes around the container to let air in.

4. Spread a layer of soil on the bottom.

5. Now start adding food waste alternately wet waste (vegetable and fruit skins) and dry waste (straw, sawdust, dry leaves).

6. Cover this container with plastic sheeting or wooden planks to help retain moisture and heat. Some advice Every few days, use a rake to turn the pile quickly to provide inflation. If you feel that the pile is too dry, sprinkle it with some water and make it moist.

Within 2-3 months, your food waste should start to form compost on dry, dark brown soil. There are also ready-made, kitted tools for food waste composting. With time and a little patience, you might enjoy composting food waste.

It is not recommended to use leftover meat, bones, leftovers, leftovers, etc. from food waste.

By sorting, ** and composting, a family of four can reduce waste by 1,000 kg to less than 100 kg per year. Imagine that 90% of all the garbage in Chennai disappeared overnight, a clean green city – and it will help you start your composting journey.

1. First of all, use the food waste dehydration separator to classify and dehydrate the food waste because the kitchen waste contains soup spoons, chopsticks, plastic bags, rags, porcelain and other inorganic substances, which not only can not be treated, but also damage the organic waste treatment equipment, so it is very necessary to sort before the kitchen waste is processed. Similarly, food waste contains a large amount of water, and it is more difficult to deal with it without filtering out the water, and the treatment cycle is long. Our food waste sorting and dehydration machine can meet the functions of sorting and dehydration at the same time, improve the efficiency of subsequent fertilizer treatment, and greatly reduce the failure rate of food waste treatment equipment.

In addition to metals, plastic products, pottery, glass, and other large inorganic garbage can not be processed, other kitchen leftovers, leftovers, vegetables, fruits and other organic waste can be put in, the equipment has continuous operation function, simple operation.

2. Then use the kitchen waste crusher to crush the food waste for the common kitchen waste bones, shell crushing, so that the bones and shells and other hard garbage are easier to carry out microbial biological fermentation, quickly reduce the amount of garbage and carry out resource utilization, and greatly realize the effective and reasonable treatment of garbage.

3. Finally, the crushed kitchen waste is processed into organic fertilizer, and the kitchen waste is crushed and then biodegraded to produce organic fertilizer. Many families use the treated organic fertilizer for crop cultivation and fertilization of flowers and plants, forming a good resource recycling.

Summary. Hello, kitchen waste treatment, disposal and recycling, refers to the classification, collection, transportation, treatment and utilization of kitchen waste, to achieve the resource utilization of food waste, while reducing environmental pollution.

Hello, the kitchen waste disposal and resource disposal refers to the classification, collection, transportation, treatment and utilization of food waste, so as to realize the resource of food waste and reduce the pollution to the environment.

The specific treatment and disposal methods include: Kitchen waste classification and collection: Separate and collect waste such as food residues and leftovers in the kitchen, and put them into the corresponding containers or bags.

Food Waste Transportation: Transporting sorted food waste to treatment centers or landfills. Kitchen Waste Disposal:

There are many ways to dispose of kitchen waste, including organic fertilizer, biomass energy, biogas power generation, etc. Kitchen waste resource utilization: Through the treatment of kitchen waste, organic fertilizer, biomass energy, biogas and other resources can be obtained, which can be used in agriculture, energy sources and other fields.

The treatment, disposal and recycling of food waste can not only reduce environmental pollution, but also provide useful resources for the society and achieve sustainable economic, social and environmental development.

Physical sorting and processing: a series of methods are used to realize the separation of various components in the garbage, and then unify**. This method maximizes the use of waste and minimizes the pollution that can be caused by garbage.

Crushing and inline method: The high-speed blade is used to break the food waste in the inner tank and flush the stirring material to the sewer, so as to solve the problem of discarding and storing food waste for residents. <

1. Physical sorting and processing: a series of methods are used to realize the separation of each component in the garbage, and then unify it. This method maximizes the use of waste and minimizes the pollution that can be caused by garbage.

2. Crushing and direct discharge method: use the high-speed blade to break the food waste in the inner tank, and then flush the stirring material to the sewer, so as to solve the trouble of discarding and storing kitchen waste for residents.

3. Landfill method: The landfill treatment of kitchen waste is an anaerobic digestion treatment method, which can decompose the organic matter into CH4 and completely dispose of the garbage. This technology is convenient and will not leave the disposal of residues, but although this method can better deal with food waste, it is for the purpose of eliminating garbage, and can not realize the reuse of food waste.

Food waste is the most important type of food waste, including food processing scraps (food waste) and edible residues (swill) generated by households, schools, canteens and catering industries. Its composition is complex, mainly a mixture of oil, water, fruit skin, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels and other substances. The amount of kitchen waste in China is very huge, and it is on a rapid upward trend.

Food waste has a significant duality of hazards and resources, and its characteristics can be summarized as follows:

1. High moisture content, up to 80%-95%.

2. High salt content, high pepper and acetic acid in some areas.

3. High content of organic matter, protein, cellulose, starch, fat, etc.

4. Rich in nitrogen, phosphorus, potassium, calcium and various trace elements.

5. There are pathogenic bacteria and pathogenic microorganisms.

6. Perishable, deteriorated, smelly, and breeds mosquitoes.

1: It refers to the garbage generated by residents' daily life and activities such as food processing, catering services, and meals provided by service units.

Including discarded unused vegetable leaves, leftovers, leftovers, aged fruit peels, eggshells, tea residues, etc.

Food waste. The main ingredient is grain.

Vegetable vegetable oil.

Animal oil. Meat and bones, etc.

There are also non-cutlery with a small amount of buckets.

Toothpicks and napkins, etc.

The main chemical component is starch.

Cellulose. Egg deficit white matter.

Lipid. and inorganic salts, etc.

At the same time, it contains a small amount of Lingkong grinding nitrogen. Phosphorus. Potassium.

Calcium. Magnesium. Sodium. Iron and other trace elements.

Crushing and direct discharge treatment: Crushing and direct discharge treatment is to directly crush and crush the food waste at the occurrence point, and then use hydraulic scouring to discharge it into the urban municipal sewer pipe network, and merge it with urban sewage into Yanla urban sewage treatment plant for centralized treatment.

Landfill treatment: Because kitchen waste contains a large number of coarse-containing sliding components, the stabilization time is short, which is conducive to the recovery of landfill sites, and is easy to operate, so it is widely used.

Fertilizer treatment: mainly includes aerobic composting and anaerobic digestion.

1. The oxygen composting process is to use the extracellular enzymes secreted by aerobic microorganisms to decompose organic matter into soluble organic matter under aerobic conditions, and then infiltrate into the cells, and realize the entire composting process through the metabolism of microorganisms.

2. It refers to the decomposition of organic waste by microorganisms under specific anaerobic conditions, in which carbon, hydrogen and oxygen are converted into methane and carbon dioxide, while nitrogen, phosphorus, potassium and other elements are retained in the residue and converted into a form that is easy to be absorbed and utilized by animals and plants.
