Description

Pollution-free treatment system for household kitchen waste

Technical Field

The utility model relates to a pollution-free treatment system for household kitchen waste.

Background

The number of kitchen waste generated in our country is about 9% per year due to the continuous improvement of people's living standard, which is estimated to reach 26 million tons per day in the initial estimation, and about one hundred million tons of kitchen waste is generated each year. The household garbage has serious harm to the environment and human beings, is an important pollution source to the environment,

1. the harm of the household kitchen waste to the land farmland:

large land occupation and farmland pollution: the land is the human clothing and food, and today, the land is damaged unprecedentedly due to the advanced development of science and technology. In which soil contamination is depriving the production capacity of large fertile fields like a soft knife. Soil pollution mainly means that certain harmful substances in soil greatly exceed normal content, and the influence of the harmful substances on the soil cannot be eliminated by the soil. Therefore, the growth and development of crops are reduced due to serious soil pollution, the yield is reduced, the product quality is reduced, even the crops are withered and die, although more soil pollution has no obvious expression, the quality of agricultural products is greatly reduced, and particularly, the agricultural products can cause great harm to livestock and human health after being eaten for a long time due to the enrichment effect of the crops on harmful substances;

2. the harm of the domestic kitchen waste to polluted underground water and surface water:

the domestic kitchen waste contains a large amount of pathogenic microorganisms, a large amount of acidic and alkaline organic pollutants are also generated in the stacking and putrefaction process, and are combined with heavy metal elements contained in the waste, including mercury, lead, cadmium and the like, so that a pollution source integrating organic matters, heavy metals and the pathogenic microorganisms is formed. The water contained in the randomly piled or simply buried garbage and the penetrating fluid generated by rainwater drenched into the garbage can flow into the water body on the surrounding ground surface to cause water body pollution. At present, most of municipal wastes are still treated by adopting a stacking and landfill method, and as a lot of landfill sites do not adopt good anti-seepage measures, pollutants inevitably pollute underground water. The garbage of the landfill site can generate penetrating fluid due to sun and rain fermentation and decomposition, can cause serious pollution to underground water and the surrounding environment, and is mainly characterized in that the underground water is turbid in water quality and has odor, the COD, ammonia nitrogen, nitric acid nitrogen and nitrous acid nitrogen are high in content, oil and phenol pollution is serious, escherichia coli exceeds the standard, and the like, and meanwhile, the garbage can cause pollution to the environment for a long time, and harm is caused to the health of people.

3. The pollution of the household kitchen waste has great influence on the air and the human health

The household and kitchen waste is piled for a long time, the waste is rotten and mildewed, a large amount of harmful gas is released, and dust and fine particles fly with wind and harm the surrounding atmospheric environment. The household garbage is randomly burnt, a large amount of toxic and harmful components are volatilized, unburned fine particles enter the atmosphere, and harmful substances such as dioxin, phenols and the like are generated. Even the direct sanitary landfill site of the household garbage can generate a large amount of landfill gas, the main components of the landfill gas are methane and carbon dioxide, the landfill gas has strong greenhouse effect, and the landfill gas also contains trace amounts of toxic gases such as hydrogen sulfide, ammonia gas, mercaptan, certain trace amounts of organic matters and the like, and if the landfill gas cannot be effectively collected, fire disasters, explosion accidents and the like can be caused.

Domestic and kitchen waste affects human health mainly through pollution of soil, atmosphere, earth surface and underground water. If the domestic kitchen waste cannot be timely and effectively treated, the domestic kitchen waste is only cleared from urban areas or simply stacked to outskirts, the waste is often spread, sewage flows transversely, mosquitoes and flies are bred and smelly, the domestic kitchen waste can also become breeding lands and breeding farms of various pathogenic microorganisms, the sanitation of the surrounding environment is directly influenced, and the health and the life safety of human bodies are harmed.

4. Pollution of domestic kitchen garbage to food

Food is one of the three major elements that make up human life and health. People eat the food as day, once the food is polluted, the food harms the health of human beings, causes various diseases, and directly threatens the life safety of human beings. The food pollution refers to various foods eaten by people, such as grains, fruits, vegetables, fish, meat, eggs and the like, and toxic and harmful substances or germs are mixed in the processes of production, transportation, packaging, storage, sale and cooking. The parasites which pollute food mainly comprise roundworms, tapeworms, trichinella and the like, generally pollute water sources and soil through excrement of patients and sick animals, then pollute fishes, fruits and vegetables, can cause various diseases after being eaten by people, and poses great threat to the health of people.

The existing household garbage treatment device can not carry out comprehensive and thorough special treatment on the household kitchen garbage, has serious threat to normal life and body health of people, and is reluctant and imperative in reasonable, safe and scientific treatment of the household kitchen garbage.
