River bank ecological slope protection belt coupled with microbial fuel cells

Abstract

The invention relates to a river bank ecological slope protection belt coupled with microbial fuel cells. The belt comprises a riverway revetment and a fuel cell net arranged inside the riverway revetment, wherein the fuel cell net comprises a plurality of fuel cells arranged in a length direction of the riverway revetment, two poles of each fuel cell is separately connected with a positive plateand a negative plate, the positive plates are buried in the riverway revetment, the negative plates are laid on the surface of the riverway revetment, the negative plates and the positive plates are connected through wires, and the wires are externally connected to storage batteries, and herbaceous plant is planted on the surface of the riverway revetment. The belt has the advantages that 1, electrode microorganisms can carry out denitrification on non-point source pollution, that is to say, carry out purification on the non-point source pollution, and meanwhile, electric energy can be generated, so that dual purposes are achieved; 2, the fuel cell net can be arranged on the whole riverway revetment, so that the purification efficiency of the non-point source pollution is greatly improved;and 3, a river bank ecological system cannot be damaged, and a positive effect is further provided for protection of the river bank ecological system.

Description

technical field [0001] The invention relates to the technical field of river ecological management, in particular to a river bank ecological slope protection belt coupled with a microbial fuel cell. Background technique [0002] my country is a traditional large agricultural production country. In order to meet the more "convenient" irrigation needs in agricultural production, most rural river channel reconstruction followed the example of urban river bank slope treatment at the beginning of this century. The rainwater runoff of pollutants enters the river, and few green plants can adapt to this harsh habitat condition, resulting in the disappearance of the ecological corridor of the river, further causing some amphibians to lose their living places, and then causing the entire biological chain of the river system to degrade and develop. disappear and destroy river ecosystems. [0003] In the prior art, the treatment of rivers and banks mainly involves reconstruction of river...

Problems solved by technology

The above-mentioned schemes all need to change the internal structure and soil environment of the original soil layer of the riparian buffer zone, thereby destroying the microbial community structure in the soil. For the riparian buffer zone, microorganisms are one of the main groups that decompose or degrade pollutants First, the damage to the structure of the riparian zone will break the balance of the microbial community, which will affect the decontamination effect

Therefore, the existing riparian buffer zone construction measures are not only not conducive to the removal of pollutants, but will also cause damage to the riparian ecosystem in severe cases.
