陶瓷膜生物反应器在传染病医院污水处理中的应用

Application of Ceramic Membrane Bioreactor in Wastewater Treatment of Infectious Disease Hospital

该文采用陶瓷膜生物反应器处理传染病医院污水,出水水质良好,COD〈40 mg/L,氨氮〈2 mg/L,浊度〈3 NTU,出水的粪大肠菌群为20-40 CFU/L,出水肠道致病菌（沙门氏菌、志贺氏菌）未检出,结核杆菌未检出,可满足《医疗机构水污染物排放标准》（GB 18466—2005）中传染病、结核病医疗机构水污染物排放限值的要求。选择高强度、高通量、抗污染的陶瓷膜,同时做好膜系统的运行维护工作,可以保证稳定达标的出水水质。

Infectious disease hospital wastewater was treated by ceramic membrane bioreactor. Results show that the effluent quality is good：COD is less than 40 mg/ L,ammonia nitrogen is less than 2 mg/ L,turbidity is less than 3 NTU,the effluent fecal coliform is 20 -40 CFU/ L,intestinal pathogenic bacteria （salmonella,hayes bacteria）in the MBR effluent is not detected,mycobacterium tuberculosis is also not detected,which can satisfy Water Pollution Discharge Standard of Medical Institution（GB 18466—2005）of infectious disease hospitals and tuberculosis medical institutions. Ceramic membrane with high strength,high flux and pollution resistance can ensure stable water quality,at the same time,a good job of membrane system running and maintenance is needed.
