Patent ID: 11339069

Abstract:
Provided are an anaerobic ammoxidation synergistic nitrogen removal process device of municipal sewage main and side streams and an application method thereof, comprising a municipal sewage raw water tank (1), a biological reaction pool (2), a secondary sedimentation pool (3), a sludge digestion solution raw water tank (4) and a sludge digestion solution AOB strengthening pool (5); wherein, the municipal sewage raw water tank (1) is connected with a water inlet valve (2.2) of the biological reaction pool (2) through a water inlet pump (2.1) of the biological reaction pool (2); the biological reaction pool (2) is connected with the secondary sedimentation pool (3) through a secondary sedimentation pool connection pipe (3.3); the sludge digestion solution raw water tank (4) is connected with a water outlet valve (4.1) of the sludge digestion solution raw water tank (4) through a water inlet pump (4.2) of the sludge digestion solution raw water tank (4); the sludge digestion solution AOB strengthening pool (5) is connected with an anaerobic ammoxidation region compartment of the biological reaction pool through a sludge-water mixture reflux pipe (5.8) and a sludge-water mixture reflux pump (5.11). It has the advantages of reasonability in structure design, convenience in operation, low running and maintenance cost, relatively low energy consumption, no need of an additional carbon source and the like, it can realize that short distance nitrification of municipal sewage is more stable, and it is high in low-temperature, water quantity and water quality shock resistance and can further increase volumetric load at the same time.
