Method for treating high-concentration nitrate waste water and municipal sewage through denitrification anaerobic ammonium oxidation SBR

The invention provides a method for treating high-concentration nitrate waste water and municipal sewage through denitrification anaerobic ammonium oxidation SBR, belonging to the field of sewage biotreatment. The method comprises the following steps: firstly, culturing and acclimating denitrifying bacteria population and anaerobic ammonium oxidation bacteria population which have inadequate denitrification characteristic, then inoculating anaerobic ammonium oxidation sludge and denitrifying sludge with high nitrite accumulation rate in the same reactor, leading nitrate waste water and municipal sewage to flow in denitrification anaerobic ammonium oxidation SBR reactor at a certain ratio, performing anaerobic ammonium oxidation to nitrite accumulated during reduction of nitrite and ammonium nitrogen in the municipal sewage to generate nitrogen gas and synchronously removing. According to the method, nitrate generated during anaerobic ammonium oxidation can be reduced through denitrifying bacteria without the condition of adding a carbon source, the nitrogen removal efficiency of a system can be improved, and the effective route for realizing sewage nitrogen removal with high efficiency and low energy consumption can be provided.
