Urban household garbage disposal system

Abstract

The invention discloses an urban household garbage disposal system. The urban household garbage disposal system is provided with a bag breaking machine (1), a belt conveyor (2), a four-shaft crusher (4), a vertical spiral gas flotation machine (5), a dissolved air flotation machine (6), a solid-liquid separator (7), sewage purification equipment (8) and a garbage disposal station house (10). By the adoption of the technical scheme, deep treatment is conducted on urban household garbage; harmful gas in the garbage can be decomposed, and meanwhile hazardous substances in the garbage can also be diluted; part of the substances are made to float and circulate, the labor intensity in the disposal process is greatly relieved, and manpower and material resources are greatly saved; the garbage serves as production raw materials, organic matter and inorganic matter in the garbage are separated and utilized reasonably for producing organic fertilizer and building block materials; white pollutants are used for producing building thermal insulation materials, and harmlessness and resource recovery of the garbage are achieved.
