Sewage treatment drum

Abstract

The invention discloses a sewage treatment drum. The sewage treatment drum comprises a sewage treater, a magnetic field generator and a membrane component. The lateral side of the sewage treater is provided with a water inlet, a filter membrane is arranged on the outer periphery of an immobilized microorganism barrel which is arranged in the sewage treater, water permeable bricks are arranged on the inner side of the immobilized microorganism barrel and support the immobilized microorganism barrel, and the membrane component is arranged on the inner periphery of the water permeable bricks and internally provided with a water outlet. The magnetic field generator comprises a spiral coil, a transformer, a power source, an iron cover and a magnetic field tester. The spiral coil is wound on the outer periphery of the sewage treater and connected with the transformer which is connected with the power source, the iron cover covers the outer periphery and the bottom of the spiral coil, the magnetic field tester is arranged in the sewage treater, and an aeration device is arranged between the inner side of the sewage treater and the filter membrane. By combination of immobilized microorganisms, aerobic and anaerobic features of microorganisms and magnetic fields, organic matter degradability of the microorganisms is improved.

Description

technical field [0001] The invention relates to the field of industrial wastewater purification, in particular to a sewage treatment cylinder. 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. 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. [0003] The traditional activated sludge meth...

Problems solved by technology

[0003] 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
