Abstract

The invention belongs to the technical field of new energy and waste water resource utilization, and discloses a drop aeration type microbial fuel cell. Specifically, a drop aeration dissolved oxygen technology will be introduced to waste water treatment process and design based on a microbial fuel cell principle, a mechanical blast aeration mode is substituted, and dissolved oxygen is provided for a negative electrode chamber of the MFC (Microbial Fuel Cell). By a new drop aeration dissolved oxygen and coupling organism power generation principle process and equipment design, biological energy conversion and waste water high-efficient treatment are achieved; and waste water enters the negative electrode chamber of a drop aeration unit after passing through a positive electrode of the microbial fuel cell, anaerobic and aerobic secondary process treatment is achieved, fully dissolved oxygen is also provided for a negative electrode of the MFC and is taken as an electron acceptor of the negative electrode, and waste water treatment recycle and biological power generation are simultaneously achieved.

Description

technical field [0001] The invention belongs to the technical field of new energy and waste water resource utilization, and specifically relates to the introduction of falling water aeration and dissolved oxygen technology into the waste water treatment process and design based on the principle of microbial fuel cells (MFC), replacing the mechanical blast aeration method, and being MFC The cathode compartment provides dissolved oxygen. The design of the new process and equipment coupled with the principle of falling water dissolved oxygen and the principle of biological electricity generation has realized the conversion of biological energy and the efficient treatment of wastewater. After the wastewater flows through the anode of the microbial fuel cell, it enters the cathode chamber through the falling water aeration unit, which not only realizes the anaerobic + aerobic secondary process treatment of wastewater, but also provides sufficient dissolved oxygen for the MFC cathod...
