Disposal system for urban domestic waste

Abstract

The invention discloses a disposal system for urban domestic waste. The disposal system is provided a bale breaking machine (1), a belt conveyor (2), a four-shaft crusher (4), a vertical spiral air floatation machine (5), a dissolved air flotation machine (6), a solid-liquid separation machine (7), sewage purification equipment (8) and a waste disposal station room (10). According to the technical scheme, the urban domestic waste undergoes advanced treatment; harmful gas in the waste can be resolved, and harmful substances in the waste can be diluted; partial substances float and circulate, the labor intensity in the disposal process is lowered greatly, and a lot of manpower and material resources are saved; the waste serves as raw production material, and organic matter and inorganic matter in the waste are separated and reasonably utilized for producing organic fertilizers and building block material; white pollutants are used for producing thermal insulation material for buildings, and harmless treating and recycling of the waste can be realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering.

Problems solved by technology

Among them, sanitary landfill wastes a lot of land resources, and it is easy to cause pollution to groundwater sources; incineration for power generation can reduce the volume of waste by 50% to 95%, but it is expensive and expensive, and it will release dioxins, mercury, etc. Harmful substances, residual slag and dust are also toxic and harmful, and a large amount of recyclable resources are burned; the composting cycle is long, and organic and inorganic substances need to be separated before they can be recycled
