Water purification device employing immobilized microorganisms

Abstract

The invention discloses a water purification device employing immobilized microorganisms. The water purification device comprises a sewage treater, an immobilized microorganism system and a film assembly, wherein the immobilized microorganism system is arranged in the sewage treater and is divided into three layers, which are a first immobilized microorganism layer, a second immobilized microorganism layer and a third immobilized microorganism layer in sequence from the outside to the inside; the first immobilized microorganism layer is formed by connecting a plurality of immobilized microorganism plates; an aeration device e is arranged between the inner side of the sewage treater and the first immobilized microorganism layer; the film assembly is arranged on the inner side of the third immobilized microorganism layer; an aeration device f is arranged between the film assembly and the third immobilized microorganism layer; and a water outlet is arranged in the film assembly. The immobilized microorganisms, the aerobic-anaerobic properties of the microorganisms and magnetic fields are combined, so that degradation of the microorganisms on organic matters is enhanced.

Description

technical field [0001] The invention relates to the field of industrial wastewater purification, in particular to a water purification device using immobilized microbial plates. Background technique [0002] Industrial wastewater is usually treated biologically. However, temperature has an important impact on the growth, reproduction, metabolism, species distribution and population size of microorganisms, which in turn affects the efficiency of sewage treatment. In addition, temperature has a great influence on the activated sludge performance and the flocculation viscosity of wastewater. [0003] With the increasingly stringent sewage treatment standards, traditional industrial wastewater treatment methods cannot meet the requirements. Especially under low temperature conditions, the metabolic capacity of microorganisms is reduced, and the rate of chemical reactions is also reduced. Therefore, the efficiency of biological treatment of wastewater will also be reduced. ...

AI Technical Summary

Problems solved by technology

[0004] The traditional activated sludge method is widely used in sewage treatment, mainly because activated sludge contains a large number of active microorganisms, which can quickly and effectively remove organic matter in sewage and have good nitrogen and phosphorus removal effects, but the traditional Activated sludge process sludge is mixed in a fluid state in sewage
