Microbial fuel cell constructed wetland device and sewage purification method

Abstract

The invention relates to a microbial fuel cell constructed wetland device. The device consists of a hydrolysis acidification pool, a microbial fuel cell constructed wetland main body and an external circuit that are connected in order. The microbial fuel cell constructed wetland main body comprises a gravel water distribution layer, an anode area, an oxygen producer layer, a cathode area and an aquatic plant from bottom to top in order. The lower part on one side of the microbial fuel cell constructed wetland main body is provided with a water inlet, the other side top is equipped with a wateroutlet, the water inlet is communicated with a water outlet at the lower part on one side of the hydrolysis acidification pool through a pump and a pipeline, and a water inlet at the lower part on the other side of the hydrolysis acidification pool is communicated with a sewage inlet pipe. The external circuit consists of an anode, a cathode and a copper core lead connected to the anode and cathode, and a circuit switch is in tandem connection to the copper core lead. The wetland device provided by the invention has the characteristics of simple structure and convenient operation, and by regulating the electrode dissolved oxygen environment, can show excellent power production efficiency while strengthening the constructed wetland sewage treatment effect.

Description

technical field [0001] The invention relates to a microbial fuel cell artificial wetland device and a sewage purification method, belonging to the technical field of sewage treatment. Background technique [0002] Energy issues and environmental issues are important issues facing the sustainable development of human society in the future. With the continuous development of the world economy, energy consumption continues to increase. Today, almost all industrialized countries are facing the problem of energy shortage and sustainable development of the environment, and the development and utilization of energy are closely related to environmental pollution. Facing the situation of energy shortage and increasingly serious environmental pollution, it is necessary to find sustainable alternative energy sources while trying to reduce energy consumption. Energy cleanliness, efficiency, diversification, and globalization are the future development trends. [0003] Sewage contains ...
