浅析医院污水治理工程工艺

Hospital Sewage Treatment Project Selection Process

医院污水成分复杂,含有重金属、消毒剂、有机溶剂等有毒有害物质,同时还含有病原微生物,具有传染性。医院用水量较大,污水中的污染物浓度和一般生活污水的污染物浓度相似,甚至更低。针对医院污水的特点,在医院污水处理设计规范的基础上,经过大量文献查阅和各种工艺的优化比选,确定该医院污水治理工程采用水解酸化-生物接触氧化-二氧化氯消毒工艺。

Hospital sewage＇s composition is complex , containing heavy metals, disinfectants, organic solvents and other toxic substances, but also contains pathogenic microorganisms, which is contagious. Hospital water using is greater, concentration of pollutants in wastewater and general concentration of pollutants like sewage, or even lower. For the characteristics of hospital wastewater, sewage treatment in the hospital on the basis of design, after a lot of literature review and comparison of various optimization techniques to determine the sewage treatment works at the hospital by hydrolytic acidification-biological contact oxidation-chlorine dioxide disinfection process.
