Abstract

The invention discloses a microbe fuel cell device for enhanced nitrogen removal in the AAO (anoxic-anaerobic-aerobic) sewage treatment technology, for enhancing sewage biological denitrogenation and generating electricity. The device structurally comprises an anode stacking, a cathode stacking, an external circuit conducting wire and an external load, wherein the anode stacking is arranged in an anaerobic reaction tank in AAO sewage treatment technology; the cathode stacking is arranged in an anoxic tank to form a biological cathode microbe fuel cell structure; and the denitrogenation is enhanced without affecting the original function of the AAO sewage treatment technology, and electricity can be generated when pollutants are removed. The device is easy to install and can be combined with the present AAO technology conveniently for use.

Description

technical field [0001] The invention relates to a device capable of strengthening biological nitrogen removal and simultaneously generating electricity in the AAO sewage treatment process. This kind of device can strengthen microorganisms to remove nitrogenous pollutants in sewage, and generate a certain amount of electric energy, while not interfering with traditional AAO sewage treatment process, and improve the efficiency of biological nitrogen removal. Background technique [0002] The AAO process is a combination of traditional activated sludge process, biological nitrification and denitrification process and biological phosphorus removal process. Since the process alternately operates three different environmental conditions of anaerobic, anoxic and aerobic, there will be a variety of facultative anaerobic fermentation bacteria, denitrifying bacteria, aerobic phosphorus-accumulating bacteria, etc. Microorganisms in the environment. Different types of microbial flora ...
