- Title:
- Sewage Treatment Project Design of Wuhan Huoshenshan and Leishenshan Hospitals
- 摘要:
- 火神山、雷神山医院是为集中收治新型冠状病毒肺炎(COVID-19)患者而设立的传染病专科医院,其污水处理系统设计均采用“预消毒接触池+化粪池+提升泵站(含粉碎格栅)+调节池+MBBR生化池+混凝沉淀池+接触消毒池”处理工艺。MBBR工艺实现了低温下污水中污染物的高效去除,两级消毒工艺保障了病毒100%消灭,同时污水站地基下方按垃圾填埋场标准铺设HDPE膜,保障雨水污水全收集并进行消毒后排放,污泥经消毒脱水后按危险废物集中清运处理,废气统一收集经除臭消毒后排放,实现雨污水、污泥、废气的全收集和全处理。当前,火神山、雷神山医院污水处理系统运行稳定,相关出水指标均已达到设计要求,其中COD稳定低于50 mg/L,氨氮稳定在2 mg/L以下,余氯稳定在13 mg/L附近,污染物去除与消毒效果均十分稳定。
- 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.
