Technical Field

The invention relates to the field of waste treatment, in particular to a waste reduction treatment system for household garbage and livestock and poultry manure.

Background

With the continuous progress of the scientific and technological development of China, the requirements of people on living environment are increasingly improved, and the requirements on the treatment and environmental protection of the living environment in cities and rural areas are also increasingly strict. In cities, the harmless treatment of domestic garbage is an important link of urban environment, the traditional landfill treatment method easily causes serious pollution to soil and occupation of land, and the existing garbage incineration often causes pollution to air; in rural areas, the problem of excrement treatment is brought while the animal husbandry is rapidly developed, the existing treatment method of the livestock excrement not only occupies a large amount of land, but also causes serious pollution to underground water and soil, and simultaneously can generate pungent smell to influence the life of surrounding residents. Therefore, a harmless decrement treatment system for municipal and rural domestic garbage, livestock and poultry manure and other wastes needs to be developed to meet the environmental protection requirement in the waste treatment process.

The main problems of the harmless treatment of the domestic garbage and the livestock manure comprise the following aspects: (1) high water content: the water content of the domestic garbage is high, and the water content of the livestock manure can exceed 80 percent at most. Therefore, the domestic garbage and the livestock manure contain relatively less organic matters. Moreover, if incineration or other treatment is used, too high a water content may result in insufficient combustion or failure of the solution. Therefore, it is necessary to take a pre-drying or solid-liquid separation treatment for the excessive water content, and the separated sewage contains a large amount of bacteria, viruses, toxic substances and the like, which pollute the environment if not treated. (2) The processing capacity is not adjustable: the volume of the existing incineration equipment is fixed. In the actual processes of waste incineration and livestock manure treatment, the daily yield of domestic waste may be greatly different, and the differences of livestock manure in different stages of cultivation are huge. This causes that if the amount of raw material is too large, the efficiency of combustion or treatment is easily affected, resulting in energy loss and deterioration of emission; if the amount of raw material is too small, the energy consumption for the treatment becomes too high. Therefore, around the national industrial policy of energy conservation and emission reduction, it is necessary to develop high-efficiency treatment technology and equipment for harmless treatment of wastes based on domestic wastes and livestock and poultry manure with the aims of building living environment, eliminating environmental pollution, and treating urban and rural wastes economically, effectively and harmlessly, and ensure that all emission indexes meet the national standard.

The above scheme has the following problems: (1) no solid-liquid separation or drying device is provided. The water content of the domestic garbage and the livestock manure is very high, and if solid-liquid separation and full drying are not carried out, a large amount of water will influence the combustion process, so that the purification efficiency of the whole equipment is influenced; (2) the emission level cannot be guaranteed.
