Dissolved air flotation machine of city and town domestic waste treatment system

Abstract

The invention discloses a dissolved air flotation machine of a city and town domestic waste treatment system. The dissolved air flotation machine is provided with an air flotation pool (19), a dissolved air water pump (22), a pressure dissolved air tank (23) and an air compressor (24). A foam scraping machine (18) is arranged on the air flotation pool (19). By means of the technical scheme, deep treatment is carried out on the city and town domestic waste. Harmful gas in the waste can be decomposed, and meanwhile harmful substances in the waste can be diluted. Part of substances float and cycle, the labor intensity in the treatment process is greatly lowered, and a large amount of manpower and a large number of material resources are saved. The waste serves as production raw materials, organic matter and inorganic matter in the waste are separated and reasonably utilized, and organic fertilizer and building block materials are produced; and building thermal insulation materials are produced through white pollutants, and harmlessness and recycling of the waste are achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering. More specifically, the present invention relates to a dissolved air flotation machine for a municipal solid waste treatment system. Background technique [0002] With the rapid development of our country's economy, a lot of resources are consumed and a lot of waste is produced, which seriously affects and restricts economic development and threatens people's living quality. Economic development and pollution control have become the consensus of modern society. The direction of environmental protection work is to implement the national development strategy of sustainable development and creating a harmonious society. Environmental protection is a basic state policy of our country. The country has listed the energy-saving and environmental protection industry as one of the seven strategic emerging industries that the country has accelerated its cultivation and develop...

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
