Abstract

The invention relates to a municipal sewage partial nitrification and anaerobic ammonia oxidation denitrification method capable of enhancing energy recuperation, and belongs to the field of sewage treatment. According to the invention, municipal sewage enters a biosorption reactor at first, organic matter in the sewage is absorbed into activated sludge through the absorption effect of the activated sludge, then the municipal sewage enters an SBR (Sequencing Batch Reactor Activated Sludge Process) reactor, and through the alternate operation of low oxygen aeration and anaerobic agitation, the autotrophic nitrogen removal of the partial nitrification and the anaerobic ammonia oxidation is realized, so that the energy recuperation efficiency of the sewage treatment is improved, and the operation energy consumption of the sewage treatment is lowered.
