Internal conductive bacteria and algae integrated microbial fuel cell ecological water body purification method

Abstract

The invention discloses an internal conductive bacteria and algae integrated microbial fuel cell ecological water body purification method. An ecological water body purification system is establishedand comprises a water inlet pipe, a double-layer pool body, a porous water collection pipe, aquatic plants, a rotatable elbow and a U-shaped drain pipe; the double-layer pool body comprises an electricity generation inner layer, a non-electricity-production outer layer and a free water layer; hydrobiontic algae grows in the free water layer; sewage enters the bottom of the electricity generation inner layer, and organic pollutants in the sewage are degraded by electricity production microorganisms. Water flow flows upwards and nitrification and denitrification nitrogen removal occurs. The water flow enters the non-electricity-production outer layer from a water through hole above the free water layer, and reoxygenation is accelerated; the non-electricity-production outer layer intercepts the hydrobiontic algae in the free water layer by filtering of a filler so as to further remove pollutants in water. According to the invention, a microbial fuel cell technology and a conventional ecological water body purification technology are integrated, purification functions of the electricity production microorganisms and the algae are coupled, and high-efficiency organic carbon metabolism and removal of nitrogen and phosphorus are compactly controlled in the same ecological water body purification system.

Description

technical field [0001] The invention belongs to a sewage treatment method, and in particular relates to an ecological water body purification method of an internal guidance type bacteria and algae integrated microbial fuel cell. Background technique [0002] With the rapid development of social economy, my country's water environment situation is becoming increasingly severe. Many problems caused by water pollution are worrisome, and various places have successively carried out the remediation work of polluted water bodies. Under such circumstances, urban point source pollution control has achieved certain results, but in the vast rural areas, the problem of water pollution has become more prominent. Rural sewage treatment has become the top priority of the current water environment. [0003] Rural pollution has the characteristics of large volume and wide area, dispersion, and spatial heterogeneity. In addition, the rural pollution control and operation and maintenance te...
