Abstract

The invention discloses a microorganism reinforced gallery pushing flow type wastewater treatment bioelectrochemical device which relates to a sewage treatment device. The invention solves the problem that the cost of BESs (bioelectrochemical systems) is increased due to weakened anode activity and high membrane cost by adopting an ion exchange membrane in the existing sewage treatment BESs. The microorganism reinforced gallery pushing flow type wastewater treatment bioelectrochemical device comprises a water inlet tank, a water inlet pump, a sewage treatment pond and a water outlet, wherein the sewage treatment pond comprises a first electrode treatment unit and a settling pond; the first electrode treatment unit comprises a first electrode treatment unit cathode chamber, a first cathode electrode, a first clapboard, a first electrode treatment unit anode chamber and a first anode electrode; the first cathode electrode is positioned in the first electrode treatment unit cathode chamber, the first anode electrode is positioned in the first electrode treatment unit anode chamber, the first cathode electrode is connected with one end of an external resistor, the other end of the external resistor is connected with a cathode of the external power supply, and the first anode electrode is connected with an anode of the external power supply; the settling pond is a settling chamber. The microorganism reinforced gallery pushing flow type wastewater treatment bioelectrochemical device is applied to the field of sewage treatment.

Description

technical field [0001] The invention relates to a sewage treatment device. Background technique [0002] The rapid development of industry in today's society has led to a sharp increase in water consumption and wastewater discharge in the production process of industrial enterprises. Most industrial wastewater is typical toxic and refractory organic wastewater. These wastewater usually contain high concentrations of biochemical refractory Organic pollutants are difficult to deal with and cause serious harm to environmental water bodies. With the aggravation of the pollution of the ecological environment, the enhancement of human awareness of environmental protection, the emphasis on the water crisis and the understanding of the accumulation of toxic substances in organisms, the restrictions on the discharge of toxic substances into water bodies are becoming more and more stringent. The traditional biological and physical and chemical purification methods cannot meet the cur...
