A microbial fuel cell device with aquatic plant electrodes in constructed wetlands

Abstract

A microbial fuel cell device for aquatic plant electrodes in constructed wetlands, which belongs to the field of environmental protection and new energy. It includes a cathode tank and an anode tank. The special feature is that the cathode tank and the anode tank are separated by a separator, and the separator has a The plate shape of the through hole; the catholyte and the cathode electrode are arranged in the cathode tank, the anolyte and the anode electrode are arranged in the anode tank, and the anode electrode, the external resistance and the cathode electrode are connected by wires in sequence; the cathode tank and the upper part of the anode tank are connected with the Higher aquatic plants are respectively planted at the air contact positions. In the present invention, the planting cost of higher aquatic plants is very low, and the whole device does not need to use expensive selective permeable membranes and traditional cathode electrode materials loaded with precious metals such as platinum and gold, which greatly reduces the manufacturing cost; the device is applied When used in pollutant purification work such as sewage treatment, it has a long operating cycle, simple maintenance, strong decontamination ability, good pollutant degradation effect, and fully utilizes solar energy to generate high power.
