The invention relates to the technical field of wastewater treatment, and discloses a three-dimensional electrode bio-membrane reactor which comprises a reactor, supporting legs are fixedly mounted on the two sides of the bottom of the reactor, a water outlet pipe is fixedly mounted on the outer wall of the reactor, a water distribution hopper is arranged at the bottom of the reactor, and a water inlet pipe is fixedly connected to the bottom of the water distribution hopper. A water inlet barrel is arranged at the tail end of the water inlet pipe, a water inlet pump is arranged in the water inlet pipe, two cathode plates are oppositely arranged in the reactor, an anode plate is arranged between the two cathode plates, and the anode plate is a graphite plate, so that the corrosion speed is low, carbon dioxide can be released when the carbon dioxide is dissolved, and the effect of buffering the PH value can be achieved after the carbon dioxide is dissolved in water; carbon dioxide can be used as an inorganic carbon source for autotrophic denitrification to provide an energy substance for denitrifying microorganisms instead of causing secondary pollution, and a graphite plate is used as a negative plate, so that the negative plate has good conductivity, is relatively rough in surface, and is beneficial to attachment growth of the microorganisms.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a three-dimensional electrode biofilm reactor. Background technique [0002] With the development of my country's industrial and agricultural production and the improvement of the level of urbanization, the discharge of urban sewage has increased rapidly. A large number of untreated or treated urban sewage whose effluent nitrogen and phosphorus are still difficult to meet the standards are discharged into urban lakes and rivers, causing nitrogen and phosphorus in the water to Pollution is becoming more and more serious, and its direct consequence is the eutrophication of water bodies. [0003] Nitrogen in water mainly exists in the form of organic nitrogen and inorganic nitrogen. Organic nitrogen includes protein, polypeptide, amino acid and urea, etc. Organic nitrogen is converted into inorganic nitrogen through microbial decomposition, mainly ammonia nitrogen, nitr...
