An ecological water body purification system with bacteria and algae integrated microbial fuel cell

Abstract

The invention discloses a peripheral guide type bacterium-alga integrated microbial fuel cell and ecological water body purification system. The peripheral guide type bacterium-alga integrated microbial fuel cell and ecological water body purification system comprises a water inlet pipe, a porous water distribution pipe, a double-layered tank body, a porous water collection pipe, a rotatable elbow, a U-shaped water discharging pipe and an aquatic plant, wherein the double-layered tank body comprises a non-power-generation inner layer, a power-generation outer layer and a free water layer; thebottom parts of the power-generation outer layer and the non-power-generation inner layer are separated and the top parts of the power-generation outer layer and the non-power-generation inner layer are communicated to form the free water layer; the power-generation outer layer is connected with input water and conductive particle filler is filled; the free water layer is arranged at the top partof the particle filler and algae grow in the free water layer; water is overflowed into the non-power-generation inner layer from the upper side of the free water layer and then flows out of the system through the a U-shaped water discharging pipe; non-conductive particle filler is filled into the non-power-generation inner layer. According to the peripheral guide type bacterium-alga integrated microbial fuel cell and ecological water body purification system, a microbial fuel cell technology and a traditional ecological water body purification technology are integrated, and purification functions of power-generation microorganisms and the algae are coupled; in a whole process, no energy consumption is caused and no external circuit is adopted, so that the system is especially suitable fortreating domestic sewage and industrial wastewater, which take carbon nitrogen phosphorus as pollutants.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an ecological water body purification system with bacteria and algae integrated microbial fuel cells. 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 technical force is we...
