Abstract

The invention relates to a nitrogen and phosphorus removal process based on multi-effect medical sewage treatment. The system comprises a mechanical grid 1, an adjusting tank 2, a first blower 3, a first pump 4, an anoxic tank 5, a contact oxidation tank 6, a second pump 7, a second blower 8, a vertical flow sedimentation tank 9, a third pump 10, a coagulation reaction tank 11, a PFS tank 12, a PAM tank 13, an inclined tube sedimentation tank 14, a fourth pump 15, a contact disinfection tank 16, a sodium hypochlorite tank 17, a sludge tank 18 and a central processor. The central processing unit is additionally arranged in the system, the water level in the designated water pool is detected, the corresponding air blower operation parameters and the corresponding dosing amount of the dosingtank are selected according to the detection result, and sludge control of the system can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical sewage treatment, in particular to a nitrogen and phosphorus removal process based on multi-effect medical sewage treatment. Background technique [0002] In recent years, the state has become more and more stringent on the environmental protection of sewage discharge. With the strengthening of environmental protection law enforcement, the final discharge of medical sewage is required to meet the "Discharge Standards for Water Pollutants in Medical Institutions" (GB18466-2005) and " Water Quality Standards for Sewage Discharged into Urban Sewers (CJ343-2010), the latter increases the requirements for total nitrogen and total phosphorus in the effluent. The total phosphorus of medical sewage is about 4-15mg / L, and the effluent requirement is below 8mg / L. After deducting the demand for phosphorus synthesized by microorganisms in the biochemical treatment section, the final effluent total phosphorus ...
