- Abstract:
- The Huoshenshan hospital and Leishenshan hospital are special infectious diseases hospitals that were designed to focus on the treatment of patients infected by new Coronavirus pneumonia (COVID-19). The design of sewage treatment system was “pre-disinfection contact tank+septic tank+lifting pump station (including crushed grille)+regulating tank+MBBR biochemical tank+coagulation sedimentation tank+contact disinfection tank”. MBBR process could achieve efficient removal of pollutants in sewage at low temperature. Two-stage disinfection process guaranteed 100% virus elimination. At the same time, HDPE membrane was laid under the sewage station according to the landfill standard to ensure the full collection, disinfection and discharge of rainwater and sewage. The sludge was collected and transported as hazardous waste after disinfection and dehydration. The waste gas was collected, deodorized and disinfected in a unified way, so as to realize the full collection and treatment of rainwater, sewage, sludge and waste gas. At present, the operations of the sewage stations of Huoshenshan and Leishenshan hospitals had kept stable, and the relevant effluent indexes met the design requirements. COD concentration was stable below 50 mg/L, ammonia nitrogen was stable below 2 mg/L, residual chlorine was stable near 13 mg/L. Therefore, the pollutant removal and disinfection effect were stable during the whole operation.
