摘要
河北省某全地下污水处理厂二期工程设计规模10×10^(4)m^(3)/d,出水水质执行《大清河流域水污染排放标准》(DB13/2795-2018)(地表水准Ⅳ类)。该工程污水处理采用五段Bardenpho工艺+气浮+臭氧氧化+紫外及次氯酸钠联合消毒;再生水部分采用超滤工艺。出水可达到准Ⅳ类标准及再生回用要求。
The design scale of the second phase project of an underground sewage treatment plant in Hebei Province is 10×10^(4)m^(3)/D,and the effluent quality is in a ccordance with the discharge standard of water pollution for Daqinghe River Basin(DB13/2795-2018)(surface level Ⅳ).Five stage bardenpho process+air floatation+ozone oxidation+ultraviolet and sodium hypochlorite combined disinfection is adopted for sewage treatment of the project;ultrafiltration process is adopted for reclaimed water.The effluent can meet the standard of class IV and the requirement of regeneration and reuse.
