厌氧酸化+生物接触氧化+紫外线消毒处理医院污水

Treatment of Hospital Sewage Using Combined Anaerobic Acidification,Biological Contact Oxidation and Ultraviolet Disinfection Process

针对广东省某医院综合污水的水质特点,采用“厌氧酸化+生物接触氧化+紫外线消毒”工艺进行处理。实际运行表明,出水水质能稳定达到“广东省水污染物排放限值(DB4426-2001)”第二时段一级排放标准以及“医疗机构水污染物排放标准(GB18466-2005)”中的最严值。项目工程总投资约50万元,实际运行成本为2.12元/m^3,本案例可以为中小型医院废水处理设计提供借鉴。

According to the water quality characteristics of a comprehensive sewage in a hospital in Guangdong province,the process of“anaerobic acidification+biological contact oxidation+ultraviolet disinfection”was adopted.The actual operation showed that the effluent water quality reached the more stringent values of the first-level discharge standard for the second period of“Guangdong Province Water Pollutant Emission Limit(DB4426-2001)”and“Water Pollutant Discharge Standard for Medical Institutions(GB18466-2005)”.The total investment of the project was about 500000 yuan,and the actual operating cost was 2.12 yuan/m^3,which can provide reference for wastewater treatment in small and medium-sized hospitals.
