摘　　要：采用生物接触氧化、膜生物反应器、两级过滤与ClO2消毒处理某医院污水。当采用生物接触氧化+ClO2联合工艺时,可使处理后的污水满足《污水综合排放标准》(GB8978—1996)一级排放标准的要求。该系统同时提供了两套中水处理工艺:(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。经过两种工艺处理后,回用水均可满足《城市杂用水水质标准》(GB/T18920—2002)的要求。经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。The methods of bio -contact oxidation, MBR, two -level filtration, and ClO2 disinfection were applied in the treatment of a hospital wastewater. When the combined process of bio - contact oxidation and ClO2 disinfection was applied, the wastewater after treated could meet the requirements of first level emissions standards of GB8978-1996. Two processes were used for producing reclaimed water： （ 1 ） bio - contact oxidation ＋ MBR ＋ ClO2 ; （2） bio - contact oxidation ＋ sand filtration ＋ active carbon filtration ＋ ClO2. Both the processes could make reclaimed water met the requirements of water quality standard for urban water consumption（ GB/T 18920-2002）. The results from a longterm operation showed that this treatment system had a high removal efficiency, stable water quality and nimble operation mode.
