Abstract

The invention belongs to the technical field of biological sewage treatment, particularly relates to an anaerobic ammonia oxidation autotrophic nitrogen-removal for municipal sewage and a method thereof, and more particularly relates to a system for realizing anaerobic ammonia oxidation autotrophic nitrogen removal of municipal sewage based on molecular state nitrite side inhibition and the methodthereof. The system is reasonable in structural design, convenient to operate and use, low in operation and maintenance cost and relatively low in energy consumption, does not need to additionally add a carbon source, and can realize more stable shortcut nitrification of municipal sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, and specifically relates to a system and method for anaerobic ammonium oxidation autotrophic denitrification of urban sewage, and more specifically to a system and method for realizing urban sewage anaerobic ammonium oxidation autotrophic denitrification based on molecular state nitrite side suppression. Nitrogen removal system and method. Background technique [0002] At present, most inland rivers and lakes in my country are polluted by different levels of nitrogen and phosphorus pollutants, and eutrophication of water bodies is frequent. The traditional sewage denitrification technology has the disadvantages of high energy consumption and low efficiency, and it is necessary to develop a new economical and efficient sewage denitrification technology. [0003] The anaerobic ammonia oxidation denitrification pathway was discovered by Dutch scientists in the 1980s. This bioche...
