Dissolved gas floatation machine of urban household garbage treatment system

Abstract

The invention discloses a dissolved gas floatation machine of an urban household garbage treatment system. The dissolved gas floatation machine is provided with a gas floatation pool (19), a dissolved gas water pump (22), a pressure dissolved gas tank (23) and an air compressor (24); and the dissolved gas floatation machine (6) is provided with an adjusting pool (13). By adopting the technical scheme, the urban household garbage is further treated; harmful gases in the garbage can be decomposed, and harmful substances in the garbage also can be released; partial substances are floated and circulated, so that the labor intensity in the treatment process is greatly alleviated, and a great amount of manpower and material resources are saved; the garbage is used as a production raw material, and organic matters and inorganic matters in the garbage are separated and reasonably utilized to produce organic fertilizers and construction building block materials; and white pollutants are used for producing construction heat-preservation materials, so that the harmless utilization and recycling of the garbage are 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
