摘要:- 火神山、雷神山醫(yī)院是為集中收治新型冠狀病毒肺炎(COVID-19)患者而設(shè)立的傳染病�？漆t(yī)院，其污水處理系統(tǒng)設(shè)計均采用“預(yù)消毒接觸池+化糞池+提升泵站（含粉碎格柵）+調(diào)節(jié)池+MBBR生化池+混凝沉淀池+接觸消毒池”處理工藝。MBBR工藝實現(xiàn)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(biāo)準(zhǔn)鋪設(shè)HDPE膜，保障雨水污水全收集并進(jìn)行消毒后排放，污泥經(jīng)消毒脫水后按危險廢物集中清運(yùn)處理，廢氣統(tǒng)一收集經(jīng)除臭消毒后排放，實現(xiàn)雨污水、污泥、廢氣的全收集和全處理。當(dāng)前，火神山、雷神山醫(yī)院污水處理系統(tǒng)運(yùn)行穩(wěn)定，相關(guān)出水指標(biāo)均已達(dá)到設(shè)計要求，其中COD穩(wěn)定低于50 mg/L，氨氮穩(wěn)定在2 mg/L以下，余氯穩(wěn)定在13 mg/L附近，污染物去除與消毒效果均十分穩(wěn)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.
