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CODcr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%。
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 CODer 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〈MW〈10 000 were only 9.76%.
