▎ 摘　　要

NOVELTY - Device comprises temperature-controlled water circulation layer (1), a reaction chamber (14) and an external circuit (13). The temperature-control water circulation layer is wrapped outside the reaction chamber. The temperature-control water circulation layer is provided with a water inlet hole (3) and a water outlet hole (4), and water is fed from the water inlet hole and discharged from the water outlet hole through a water pump (2) to perform temperature-control water circulation. The reaction chamber is an anode chamber (5), a graphite felt anode sheet (6) is contained in the anode chamber. The graphite felt cathode sheet (7) is arranged outside the anode chamber. The top of the anode chamber is provided with a sample inlet (8). The side wall is provided with a sampling port (9), and the bottom is provided with a sample outlet (10). USE - Device for treating aquaculture sewage by using air cathode single-chamber microbial fuel cell. ADVANTAGE - The device has simple and convenient self temperature control operation and simple and easy device manufacture. The cathode graphite felt is modified by the graphene to effectively reduces the resistance of the cathode of the battery, the coating of the platinum-carbon powder effectively improves the catalytic action of oxygen in the air, the culture wastewater contains high-concentration organic matters to supply energy to microorganisms, and the domestication speed is faster. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for method for treating aquaculture wastewater by using an air cathode single-chamber microbial fuel cell, which involves: (1) attaching microorganisms to the graphite felt anode sheet decompose organic matters in the aquaculture sewage to generate protons and electrons, the protons are directly transferred in the anode reaction liquid to reach the graphite felt cathode sheet, the electrons reach the graphite felt cathode sheet through a titanium wire of an external circuit, and finally oxygen is reduced on the graphite felt cathode sheet and combining with the protons to generate water. (2) The breeding wastewater in the anode reaction solution contains high-concentration organic matters and various microorganisms, so that the electrogenesis microorganisms are rapidly attached to and accumulated on the graphite felt anode sheet, and the domestication speed and the electrogenesis reaction process are accelerated. DESCRIPTION OF DRAWING(S) - The drawing shows schematic diagram of a device for treating aquaculture sewage.
