摘要
采用水解酸化/生物接触氧化/纤维球过滤/次氯酸钠消毒工艺处理医院污水,处理规模为500 m3/d,其中300 m3/d出水水质可以达到《污水综合排放标准》(GB 8978—1996)的二级标准,其余200 m3/d经深度处理后达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)标准,可用作冲厕、绿化用水。
The combined process of hydrolysis acidification, biological contact oxidation, fibrous filtration and NaCIO disinfection is used to treat domestic sewage from a hospital. The treatment capacity is 500 m3/d, in which 300 m3/d effluent quality can reach the second criteria specified in Integrated Wastewater Discharge Standard （GB 8978- 1996）, and other 200 m3/d effluent, after advanced treatment, can reach the requirement of Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption （GB/T 18920 -2002）, being used for toilet flushing and greening.
