Manufacturing method for quickly processing municipal solid waste and derivatives at high temperature

Abstract

The invention relates to a manufacturing method for quickly processing municipal solid waste and derivatives at the high temperature. The manufacturing method is characterized in that the municipal solid waste, waste plant powder, kitchen waste, quick lime, ferrous sulfate, magnesium sulfate and chlorine dioxide are uniformly mixed, sealed high-temperature fermentation equipment is adopted, the temperature of the interior of the fermentation equipment is increased to 100 DEG C through oil-electricity heat conducting and keeps for 2 hours, the temperature is kept at 60-80 DEG C, a thermophilicanti-high-temperature active multiple species inoculant is added for fermentation, the intermittent stirring function of a fermentation machine stirring system is performed, the municipal solid wasteferments in the fermentation machine for 12 hours, and harmful microorganism eggs, weed seeds and pathogenic bacteria in the municipal solid waste are effectively killed; the fermented clinker is madeinto powder through an ageing smashing screen, and the powder is weighed by an automatic electronic scale and packaged into organic matter products through packaging machine; and accordingly, the municipal solid waste disposal problem is solved, recycling comprehensive utilization of the municipal solid waste is achieved, and pollution to the natural environment is reduced.

Description

technical field [0001] The invention relates to a manufacturing method for rapid treatment of municipal solid waste and its derivatives at high temperature. Specifically, it uses mechanical and automatic high-temperature rapid fermentation, aging, and disinfection of municipal solid waste, waste plants and kitchen waste. , drying, pulverizing and sieving garbage derivative powder, which is used as the main raw material to produce soil remediation improver and organic compound fertilizer, which belongs to the field of waste treatment. [0002] The present invention also relates to a method for producing the garbage derivative.

[0003] The earth is the home on which human beings live and provides a beautiful environment for human survival; however, with the rapid development of urbanization in our country, the planning of urban construction is gradually expanding, the urban population is increasing year by year and people's living standards are improving day by day, urban life The amount of garbage produced is also increasing year by year; said municipal solid waste is the garbage produced in people's daily life and consumption process, the garbage produced by commercial activity places, government agencies, schools, corporate offices and entertainment places, and the operation of urban farmers' markets The rotten fruits and vegetable leaves and roots produced in the process, and the mixed solid waste produced by sanitation workers in the process of cleaning communities, streets, squares, and roads; there are many kinds of them, mainly from residents' life and consumption, municipal construction and maintenance, commercial waste, etc. Activities, urban landscaping and farming production, farmers' markets, medical and entertainment venues, etc. produce general garbage, human and animal feces, and kitchen residue garbage; our home is being surrounded by urban domestic garbage; caused by domestic garbage Environmental pollution is becoming more and more serious. At present, the amount of domestic waste produced by 660 large and medium-sized cities in China has reached more than 150 million tons per year, and it is growing at an annual growth rate of about 10%. The burial sites have been filled or are about to be filled, and it is unsustainable. The situation of garbage besieging the city is very serious; a lot of garbage piled up together, not only occupying a lot of land, but also producing some toxic and harmful substances, emitting bursts of bad smell At the same time, it breeds mosquitoes, flies, cockroaches, and rats, spreads diseases, and is extremely harmful to people's health; urban domestic garbage has become a common problem faced by all countries in the world; cities in our country are suffering from the pain of garbage siege, The composition of municipal solid waste is relatively complex, among which there are many biological pollutants. The decayed organic matter in domestic waste also contains various harmful pathogenic microorganisms, as well as plant pests, weed seeds, insects and insect eggs, which are easy to cause Biological pollution; more pathogenic bacteria, viruses, protozoa and metazoans, especially intestinal pathogenic organisms will be produced in domestic garbage and fecal sewage; typical parasites include amoeba lytic tissue, various nematodes , roundworms, hookworms, schistosomiasis, especially roundworm eggs are widely found in sewage and domestic garbage; in addition, there are fungal organisms, and the pathogenic bacteria in them can be transmitted to the human body to cause diseases under certain conditions; the most dangerous of feces to the human body Pollution is biological pollution. Untreated domestic garbage and feces pollution can enter the water body, causing biological pollution of the water body, which may cause the outbreak of infectious diseases and spread a variety of diseases; 70% of the diseases are caused by the absence of garbage and feces. Harmless treatment causes biological pollution to water bodies; in short, municipal solid waste itself has certain biological pollution, which has harmful effects on the environment and human health, and the formation of organic pollutants and odors will become a threat to urban environmental sanitation. Therefore, how to carry out biotransformation of domestic waste, make it stable and eliminate the above-mentioned pathogenic organisms is of great significance; governments at all levels and relevant departments are actively looking for effective treatment technologies. born The treatment method of living garbage is mainly to adopt simple landfill method to reduce the pollution to the natural environment; however, the composition of domestic garbage is relatively complex, with high moisture content, and the treatment is difficult. If it is directly landfilled without treatment, It will pollute the soil and groundwater sources, easily produce new secondary pollution, and cause serious harm to the environment; long-term landfills need to occupy a large amount of land resources, how to properly and scientifically dispose of domestic waste to make it harmless and Recycling has become a major research topic widely concerned by scientific and technological personnel in China; from the perspective of resource development and utilization and economic development on the basis of protecting the ecological environment, a high-temperature rapid treatment of municipal solid waste of the present invention And the manufacturing method of garbage derivatives creates a new technical route for the treatment and disposal of domestic garbage, and lays a good foundation for improving the living environment in cities and towns and improving the level of ecological civilization construction
