利用两种生物膜技术处理高校生活污水进行了试验研究,结果表明,接触氧化法优于生物转盘法;在停留时间为4h,接触氧化法对CODCr和NH3-N的去除率分别为78.5%和75.6%,出水能达到《城市污水再生利用城市杂用水水质(》GB/T18920-2002)标准;随着气水比的增大,CODCr、NH3-N的去除率先增大后减小,其适宜的气水比为15∶1;出水CODCr浓度随CODCr容积负荷的增大而升高,合理的CODCr容积负荷为6~8kgCODCr/(m3.d).

The experimental study on two bio-film process for the treatment of domestic sewage on university campus was carried out.The results show that bio-contact oxidation process is preferable to rotate biological contactor process.The removal ratio of CODCr,NH3-N by bio-contact oxidation process are 78.5% and75.6% under HRT=4h,and the quality of the effluent water meets the requirement of Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T18920-2002).The efficiency of bio-contact oxidation process increases first and then reduces with the growth of the ratio of air to flow wastewater,and the suitable portion is 15∶ 1.The effluent CODCr concentration rises with the growth of CODCr volume loading,the suitable CODCr volume loading was 6~8kgCODCr/(m3·d).
