| titleOfInvention | Device for realizing advanced treatment of secondary effluent of municipal sewage by partial reduction coupling ammonia oxidation of nitrate and real-time control method |
| abstract | Method for realizing municipal sewage II by partial reduction coupling ammonia oxidation of nitrateA device for advanced treatment of stage effluent and a real-time control method belong to the technical field of biological sewage treatment. The invention utilizes the organic carbon source in the municipal sewage to provide partial reduction coupling ammoxidation of nitrate of an electron donor to realize the advanced treatment of secondary effluent of the municipal sewage, an automatic control system is arranged in a Sequencing Batch Reactor (SBR), the automatic control system comprises chemical oxygen demand, ammonia nitrogen and nitrate nitrogen on-line monitoring sensors, and NH collected on-line is subjected to 4 + ‑N、NO 3 ‑ the-N, COD signal is input into the on-line parameter controller, and through setting the automatic control program, the regulation signal is output and acted on each execution unit controller to regulate COD/NO in the reactor in time 3 ‑ -N and NH 4 + ‑N/NO 3 ‑ -mass concentration ratio of N. The method improves the denitrification efficiency of the anaerobic ammonia oxidation process of the municipal sewage, fully utilizes the organic carbon source in the municipal sewage, improves the accumulation efficiency of nitrite, reduces the operation cost, is easy to operate, and can realize stable and efficient denitrification of the municipal sewage. |
