摘要
采用间歇循环膜生物反应器处理传染病医院污水,出水水质良好,出水ρ(COD)<30 mg/L,ρ(氨氮)<2 mg/L,ρ(TN)<15 mg/L,达到GB 18918—2002《城镇污水处理厂污染物排放标准》中的一级A标准,出水TP平均质量浓度为0.82 mg/L,对出水进一步化学除磷后,可使TP达到一级A标准。出水浊度<3 NTU,出水中粪大肠菌群、肠道致病菌(沙门氏菌、志贺氏菌)、结核杆菌均满足GB 18466—2005《医疗机构水污染物排放标准》中传染病。
Using the intermittent cycle membrane bioreactor treatment infectious disease hospital wastewater, effluent quality is good, the COD 〈30 mg/L, ammonia nitrogen 〈2 mg/L, TN 〈15 mg/L, reach Standard A of the first class in ＂Discharge standard of pollutants for municipal wastewater treatment plant＂（GB 18918—2002）. In water total phosphorus average concentration of 0.82 mg/L, with further chemical phosphorus removal, it can also make the TP achieve Standard A of the first class. Effluent turbidity 〈3 NTU, the fecal coliform bacteria in water, the intestinal pathogenic bacteria（salmonella, hayes bacteria）, mycobacterium tuberculosis all meet ＂water pollution discharge standard of medical institution＂ in infectious diseases, tuberculosis water pollutant emission limit requirements of medical institutions.
