Abstract

The invention discloses a short-cut nitrification and anaerobic ammonia oxidation integrated-endogenous short-cut denitrification and anaerobic ammonia oxidation integrated domestic sewage treatment process and belongs to the field of biological sewage treatment. Involved devices mainly comprise a water inlet tank, a first SBBR, a second SBBR, two middle water tanks and a water outlet tank. Domestic sewage firstly enters the first No.1 SBBR for anaerobic stirring to store an internal carbon source; an effluent enters a the second SBBR for synchronous short-cut nitrification anaerobic ammonia oxidation reaction, most ammonia nitrogen is removed, and nitrate nitrogen and nitrogen are generated; and then the effluent enters the first SBBR again for synchronous endogenous short-cut denitrification anaerobic ammonia oxidation reaction to generate a small amount of nitrate nitrogen and nitrogen. Advantages of organic matters in the domestic sewage and the anaerobic ammonia oxidation reactionare fully utilized, high efficiency and energy saving are realized, and deep denitrification of the domestic sewage can be realized.

Description

Technical field[0001]The present invention relates to a process for the integrated short-cut nitrification anaerobic ammonia oxidation-endogenous short-cut denitrification anaerobic ammonia oxidation integrated treatment of domestic sewage, which belongs to the technical field of sewage biological treatment and is suitable for urban domestic sewage with a low C / N ratio Processing.Background technique[0002]Water is the source of life. The earth itself has limited freshwater resources. The acceleration of modernization has exacerbated water pollution, and the situation of water shortages is becoming more and more severe. Traditional nitrification and denitrification processes have problems such as high aeration energy consumption and large remaining sludge output. Humans urgently need new energy-saving and efficient sewage treatment processes. The anammox process has received widespread attention due to its high nitrogen removal rate, no aeration, no organic carbon source, and low res...
