Abstract

The invention discloses a waste water purification apparatus of an artificial wetland coupled with a microbial fuel cell. On the basis of the artificial wetland, electrodes are arranged, a cathode andan anode are connected with an external resistor through conducting wires, and a multimeter is connected with the external resistor to measure the output voltage. The apparatus can be reconstructed on the basis of an original artificial wetland to achieve dual effects of purifying water quality and improving production capacity. The energy is extracted from wastewater, the transformation of chemical energy to biological energy to electric energy is realized, and the waste comprehensive utilization is achieved. According to the apparatus, pollutants in water can be benignly circulated, and atthe same time the energy utilization of resources can be realized. The apparatus has relatively good economic cost, simple operation and maintenance, and simple and easy and feasible electrode form, and the inherent defect that expensive electrodes are needed to be used in the microbial fuel cell is directly avoided, so that the apparatus has the advantage of practical engineering popularization.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment and microbial synchronous power generation, and in particular relates to a wastewater purification device coupled with a microbial fuel cell in an artificial wetland. Background technique [0002] Energy shortage and water pollution are facing more and more challenges with the continuous advancement of industrialization. The large amount of wastewater produced in the brewing process has become one of the serious sources of water pollution. If it is not treated and discharged directly, it will cause serious damage to the environment. Negative impact. [0003] Brewery wastewater has the remarkable characteristics of high biodegradability and easy biodegradation. The traditional treatment method is a combination of anaerobic treatment and aerobic biological treatment. However, this method has unavoidable defects, that is, the COD of the effluent is still high. It will still affect the w...
