Granular sludge-containing microbial fuel cell device

Abstract

The invention discloses a granular sludge-containing microbial fuel cell device. The granular sludge-containing microbial fuel cell device comprises an anode chamber, a cathode chamber and a precipitation chamber, wherein holes are formed in the side wall of the anode chamber; the outer part of the side wall of the anode chamber is wrapped with an ion exchange membrane; the cathode chamber surrounds the anode chamber; a liquid outlet for discharging water into the precipitation chamber is formed in the top of the cathode chamber; a liquid distributor and anaerobic granular sludge are arrangedinside the anode chamber; and aerobic granular sludge is arranged inside the cathode chamber. The granular sludge-containing microbial fuel cell device not only can perform sewage treatment, but alsocan generate electricity through the action of microorganisms with wastewater as an energy source, so that comprehensive and reasonable resource utilization is achieved. The granular sludge-containingmicrobial fuel cell device adopts a simple and easily implemented operating method, is small in land occupation and low in investment, achieves continuous operation, can treat high-concentration organic wastewater, has very high pollutant removing efficiency, and has a broad engineering application prospect.

Description

technical field [0001] The invention relates to a microbial fuel cell device, in particular to a granular sludge microbial fuel cell device. Background technique [0002] Microbial Fuel Cell (MFC) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. and Proton. Electrons are effectively transferred between the biological components and the anode relying on electron transfer mediators, and are transferred to the cathode through an external circuit to form a current. The protons are transferred to the cathode through the proton exchange membrane. The oxidant is generally oxygen, and the electrons obtained at the cathode are reduced. Protons combine to form water. [0003] Anaerobic Granular Sludge was developed in the early 1980s. It is composed of methanogenic bacteria, acetogenic bacteria and hydrolytic fermentation bacteria under high hydraulic shear. Its settling property is better than that of active sludge. ...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the anode microorganisms of microbial fuel cells use ordinary anaerobic sludge, and most of the cathode microorganisms use conventional flocculent activated sludge. The above-mentioned microbial fuel cells have a certain power generation function, but limited by microorganisms, their organic load is low and cannot be greatly improved.

In addition, at present, microbial fuel cells mostly adopt the sequential batch operation mode, and the hydraulic load is limited.
