A microbe-coupled low-temperature plasma wastewater purification device

Abstract

The invention discloses a microbiological coupled low-temperature plasma wastewater purification device which is composed of a motor, a purification system and a bracket, wherein the purification system comprises a liquid storage unit, a microbiological filler layer, a low-temperature plasma unit, a filter layer, a water inlet and a water outlet. According to the device, the purification system main body is set to be drum-shaped, the lower half part is submerged in wastewater, the drum is driven to rotate by the motor, and the wastewater and air alternatively circulate in the microorganism-containing filler layer. Therefore, aerobic demands of microorganisms can be met without an aerating apparatus, and the cost is reduced. Moreover, a low-temperature plasma treatment device is arranged ina central position of the drum, so that the wastewater degraded by the microorganisms is further decomposed and purified. The device is high in wastewater purification efficiency and low in cost, andthe quality of the purified water is high. The device disclosed by the invention integrates filtration, adsorption and decomposition, and is simple and convenient in assembly, easy to operate, smallin floor space and high in wastewater treatment capacity.

Description

technical field [0001] The invention belongs to the field of waste water purification and treatment, and in particular relates to a microorganism-coupled low-temperature plasma waste water purification device. Background technique [0002] With the rapid development of my country's industrialization and the further improvement of agricultural intensification, industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of industrial wastewater is directly discharged into rivers, lakes and other water bodies without treatment. At the same time, excessive application of chemical fertilizers and spraying of highly toxic and high-residual pesticides are common in farmland, resulting in increased agricultural non-point source pollution and eutrophication of water bodies. serious. As a result, the overall deterioration and eutrophication of water quality in rivers and lakes have been caused, and a series of global ...

AI Technical Summary

Problems solved by technology

[0005] Microbes have strict requirements on the living environment, especially the oxygen demand of aerobic bacteria. At present, most biological purification equipment need to add an additional gas explosion device to meet the requirements of microbial growth and metabolism. The gas explosion device will inevitably increase the cost of wastewater treatment. Therefore, it is imperative to find a technology and device that can meet the oxygen demand of microorganisms without increasing the cost of wastewater treatment.
