摘要
某医院采用生物法(接触氧化或膜生物反应器)、2级过滤、ClO2消毒处理污水。运行时采用生物接触氧化+ClO2联合工艺,出水的主要污染指标满足《医疗机构水污染物排放标准》(GB18466-2005)的要求。系统同时提供了2套中水处理工艺:①生物接触氧化+膜生物反应器+ClO2消毒工艺;②生物接触氧化+砂滤+活性炭过滤+ClO2消毒工艺。经过2工艺处理后,出水均可满足《城市杂用水水质标准》(GB/T18920-2002)的要求。工程的长期运行效果表明,该系统的污染物去除效率较高,出水水质稳定,且操作方式灵活,运行费用较低。
The joint applying of biological contact oxidation and CIO2 disinfection, were applied on hospital sewage treatment. The water quality of the effluent could meet the discharge standard of water pollutants for medical organization （GB 18466-2005 ）. Two treat- ment processes used for producing reclaimed water were provided including （1） bio-contact oxidation, MBR and CIO2; （2） bio-contact oxidation, sand filtration, active carbon filtration and C102. The running tests indicated the effluent meet the water quality standard for urban water consumption （ GB/T 18920-2002 ）, the treatment systems have high removal efficiencies, stable water quality, nimble operation mode and lower running cost.
