- Sewage Treatment Project Design of Wuhan Huoshenshan and Leishenshan Hospitals
摘要:- 火神山、雷神山醫院是為集中收治新型冠狀病毒肺炎(COVID-19)患者而設立的傳染病專科醫院，其污水處理系統設計均采用“預消毒接觸池+化糞池+提升泵站（含粉碎格柵）+調節池+MBBR生化池+混凝沉淀池+接觸消毒池”處理工藝。MBBR工藝實現了低溫下污水中污染物的高效去除，兩級消毒工藝保障了病毒100%消滅，同時污水站地基下方按垃圾填埋場標準鋪設HDPE膜，保障雨水污水全收集并進行消毒后排放，污泥經消毒脫水后按危險廢物集中清運處理，廢氣統一收集經除臭消毒后排放，實現雨污水、污泥、廢氣的全收集和全處理。當前，火神山、雷神山醫院污水處理系統運行穩定，相關出水指標均已達到設計要求，其中COD穩定低于50 mg/L，氨氮穩定在2 mg/L以下，余氯穩定在13 mg/L附近，污染物去除與消毒效果均十分穩定。
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.
