摘　　要：以某新建大型平战结合医院为例,针对污水成分复杂、含致病菌、功能需求特殊的特点,给出了污水处理站的设计方案,提出了具有可执行性的平疫转换方法;二级处理采用Waterbro生物膜工艺,运行结果表明,COD、 BOD5、 NH3-N出水质量浓度分别在37.1、 13.3、 12.0 mg/L以下,粪大肠菌群数为100 MPN/L,总余氯质量浓度平时3.6 mg/L、疫时7.0 mg/L均满足要求,疫时未检出传染病菌,出水水质均远优于设计标准值,转换模式合理可靠。Taking a new-built large-scale hospital for both normal and emergency use as an example,considering the complex composition,pathogenic bacteria-containing,and special functional requirements of the sewage,a design scheme for the sewage treatment station was proposed,with an executable method for normal-emergency conversion pointed out at the same time.Adopting Waterbro biofilm process for the secondary treatment,the operation results showed that,the mass concentrations of COD,BOD5,and NH3-N in the effluent water were below 37.1,13.3 and 12.0 respectively,the number of fecal coliforms was 100 MPN/L,the total residual chlorine mass concentrations were 3.6 and 7.0 mg/L in normal and epidemic situation respectively,both of which met the requirements.No infectious bacteria were detected during the epidemic.The effluent water quality was far superior to the design standard,and the conversion mode was reasonable and reliable.
