Abstract

The invention discloses a method and a device for simultaneously carrying out wastewater treatment and power generation by using a photocatalysis associated microbial fuel cell technology. The device takes conductive glass coated with an n-type semiconductor photocatalyst film as an outside wall of a cathode chamber and takes conductive glass coated with an n-type semiconductor photocatalyst film as an outside wall of an anode chamber, a conductive filler respectively connected on the outside walls of the cathode chamber and the anode chamber is used as an electrode of a microbial fuel cell. The conductive filler is a carbon fiber rope for microbial growth. Denitrifying bacteria and nitrifying bacteria are respectively cultivated at the cathode and anode of the microbial fuel cell, and mainly used for the degradation of organic matters and the removal of ammonia nitrogen. Under the irradiation of ultraviolet light, electrons flow from the anode to the cathode, so that the anode has strong oxidability, and the cathode has strong reducibility. In the invention, the functions of microbial fuel cells and a photocatalysis technology are mutually associated, so that the wastewater treatment cost is low, and the generating capacity is large.

Description

technical field [0001] The invention relates to photocatalytic technology and microbial fuel cell technology, in particular to a method and device for treating sewage with photocatalytic and microbial fuel cell technology and simultaneously generating electricity. technical background [0002] Microbial Fuel Cell (MFC for short) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. In the anaerobic environment of the anode chamber, organic matter decomposes under the action of microorganisms and releases electrons and protons. Electrons rely on suitable electron transfer mediators to efficiently transfer between biological components and the anode, and transfer to the cathode through an external circuit to form an electric current, while protons transfer to the cathode through the proton exchange membrane. The oxidant gets electrons at the cathode and is reduced to combine with protons to form water. The study fo...
