Internal guide type bacterium-alga integrated microbial fuel cell ecological water purification system

Abstract

The invention discloses an internal guide type bacterium-alga integrated microbial fuel cell ecological water purification system. The system includes a water inlet pipe, a double-layer pool body, a porous water-collecting pipe, aquatic plants, a rotatable angle fitting and a U-shaped water-discharging pipe; the double-layer pool body includes an electricity-generating inner layer, a no-electricity generation outer layer and a free water layer; aquatic algae are grown in the free water layer; sewage enters the bottom of the electricity-generating inner layer, and organic pollutants in the sewage are degraded by electricity-generating microorganisms; a water flow flows upwards, and nitrification and denitrification occur; the water flow enters the no-electricity generation outer layer fromwater passing holes in the upper part of the free water layer, and reaeration is accelerated; and the no-electricity generation outer layer intercepts the aquatic algae in the free water layer throughthe filtration effect of a filler, and pollutants in the water are further removed. According to the system provided by the invention, a microbial fuel cell technology and a traditional ecological water purification technology are integrated, the electricity-generating microorganisms and the purification function of the algae are coupled, and high-efficiency organic carbon metabolism and removalof nitrogen and phosphorus are compactly controlled in the same ecological water purification system.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an ecological water body purification system of an internal guide 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 t...
