摘要/Abstract

摘要： 膜生物反应器与生物接触氧化法处理难降解废水的对比研究表明，在相同的运行条件下，膜生物反应器比生物接触氧化法具有更稳定的出水水质，其平均出水COD_cr去除率达到88.41%，比接触氧化法提高了近30%；其平均色度去除率达到85.27%，相比接触氧化法，提高了近30%。通过出水分子量组成分析发现，膜出水以分子量介于3 000和10 000之间的物质为主，占总数的88.36%，接触氧化以分子量大于10 000的物质为主，占总物质的72.04%，介于3 000和10 000之间的仅占9.76%。

Abstract: Under the similar operational conditions, a comparison between membrane bioreactor (MBR) and biocontact oxidation method was carried out. MBR demonstrated a more excellent effluent quality than that of biocontact oxidation. In the MBR effluent, the average removing rate of COD_cr was 88.41%, higher 30% than that of biocontact oxidation;the removing rate of colority was 85.27% on average, higher nearly 30% than that of biocontact oxidation. The effluent compositions of the biocontact oxidation and the MBR were quite different. In the MBR effluent, both macromolecules with MW<10 000 and small molecules with MW>3 000 were dominant, approaching 88.36%. In the biocontact oxidation effluent, however, macromolecules with MW>10 000 were the major components, occuping with 72.04%, and molecules with 3 000
