厌氧酸化+生物接触氧化+次氯酸钠消毒医院废水工程实例

Treatment of Hospital Wastewater Using Combined Anaerobic Acidification,Biological Contact Oxidation and Sodium Hypochlorite Disinfection Process

医院废水作为一类特殊废水类型,已成为越来越多的关注热点。本项目针对怀化市某医院废水的特性,采用"厌氧酸化+生物接触氧化+次氯酸钠消毒"工艺进行处理。实际运行表明,出水水质能稳定达到《医疗机构水污染物排放标准》(GB18466-2005)排放要求。项目总投资92.52万元,每吨污水综合处理运行费用0.54元,可为其他同类型医院废水处理工程提供示范。

As a special type of wastewater,hospital wastewater has become more and more attention.The process of anaerobic ccidification,combined biological contact oxidation and sodium hypochlorite disinfection was used for treating the wastewater from a hospital in Huaihua City,according to the characteristics of its own.The operation results showed that the effluent quality could meet the discharge requirements of the discharge standard of water pollutants for medical organizations(GB 18466-2005).The total investment of the project was 925200 yuan,and the operation cost of comprehensive wastewater treatment was0.54 yuan per ton wastewater,which can provide demonstration for other similar hospital wastewater treatment projects.
