Abstract

The invention discloses an anaerobic membrane reactor-partial nitrification-anaerobic ammonium oxidation combination device and method. The device is used for treating sewage by utilizing an anaerobicmembrane bioreactor and a partial nitrification-anaerobic ammonium oxidation combination process, and organic matters in the sewage are removed in the anaerobic membrane bioreactor, so that efficientcarbon-nitrogen separation is realized; part of ammonia nitrogen is converted into nitrite nitrogen under the action of nitrozation in a partial nitrosation reactor; ammonia nitrogen and sub-nitrogengenerate nitrogen to be discharged under the action of anaerobic ammonium oxidation in an anaerobic ammonium oxidation reactor; and nitrate nitrogen can be generated at an anaerobic ammonium oxidation stage, so that an effluent partially flows back to the front end of a nitrosation reactor, nitrate nitrogen is reduced to form nitrite nitrogen, and furthermore, the deep removal of the organic matters and nitrogen is realized. Efficient energy recovery, operation energy consumption reduction, operation stability and high carbon-nitrogen pollutant removal efficiency are realized on the basis that sewage treatment is guaranteed to reach the standard.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a process and device for anaerobic treatment of wastewater and autotrophic denitrification treatment, in particular to an anaerobic membrane bioreactor-partial nitrosation-anammox combined device and its treatment method. Background technique [0002] The traditional biological treatment activated sludge process is mature and widely used in urban sewage treatment and high-concentration organic wastewater treatment projects. However, there are still many problems in this process, such as high energy consumption, high operating costs, and large floor space. Therefore, it is of great significance to develop new sewage biological treatment processes that combine energy recovery and high-efficiency pollutant removal, with low operating costs and a small footprint. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provi...
