Abstract

The invention discloses a sewage treatment device of a membrane bioreactor / microbial fuel cell, and relates to the field of a sewage treatment device. The device disclosed by the invention is aimed at solving the technical problems that the removal rate of total nitrogen of the existing membrane bioreactor is low and the technological process of combining the existing denitrification technology with a membrane bioreactor is complicated and the effect of removing total nitrogen is bad and the cost is high. The sewage treatment device of a membrane bioreactor / microbial fuel cell is a sewage treatment device of a bioreactor / microbial fuel cell formed by connecting a water inlet tank, a water inlet pump, a sewage treatment pool, a self-sucking pump, a water outlet and an aeration device, wherein the sewage treatment pool comprises a first microbial fuel cell, a membrane bioreactor and a second microbial fuel cell; and the aeration device consists of a first macroporous aeration head, a microporous aeration head, a second macroporous aeration head, a first control valve, a second control valve and an air compressor. The device disclosed by the invention is applied to the field of sewage treatment.

Description

technical field [0001] The invention relates to a sewage treatment device. Background technique [0002] With the pollution of environmental water bodies and the rapid increase of population, people's demand for water resources is also increasing day by day. However, my country is a country short of water, and the available water resources are gradually decreasing due to the influence of various factors. In this context, the emergence of sewage reuse technology will alleviate the shortage of water resources in my country to a certain extent. The technologies for sewage reuse mainly include flocculation, sedimentation, filtration, activated carbon adsorption, ion exchange, etc. These processes are generally The tertiary treatment is carried out after the traditional secondary treatment. The process is relatively complicated and the cost is high. The emergence of membrane bioreactor has created another way for sewage reuse. Membrane bioreactor is a new type of water treatment ...
