Abstract

The invention discloses a rotating disc type activated carbon bed and low-temperature plasma integrated waste water treatment facility. The rotating disc type activated carbon bed and low-temperature plasma integrated waste water treatment facility comprises a sewage tank, wherein a rotating shaft is erected on the sewage tank, the rotating shaft is used for driving a rotating disc to rotate, and the rotating disc comprises an outer frame, an inner frame and a plasma corona discharge electrode. The rotating disc type activated carbon bed and low-temperature plasma integrated waste water treatment facility has the advantages of wide application range, high treatment efficiency, low equipment cost, low operating cost, cleanliness, low cost and stable operation, solves the problem that partial sewage is difficult to degrade at present, can be an indispensable main force in the sewage treatment technology in the future and can be widely applied to the field of treatment on multiple pollutants.

Description

technical field [0001] The invention belongs to the field of sewage treatment and relates to a waste water treatment device integrated with a turntable activated carbon bed and low-temperature plasma. Background technique [0002] With the continuous development of the industrial economy, environmental problems have become increasingly prominent and have become the focus of people's increasing attention. The wastewater brought by industrial production has caused more and more serious environmental pollution. Although some industrial organic wastewater with simple components and easy degradation can pass through Traditional physical, chemical and biological combined processes can be effectively treated, but for now, for highly toxic and high-concentration organic wastewater that is difficult to be biodegraded, a reasonable and effective treatment has not been found due to insufficient technology and economy. method. At the same time, with the further highlight of the water r...
