【摘要】 采用MBR(膜生物反应器)及MBR-PAC(PAC,粉末活性炭)组合工艺处理微污染湖水.试验考察了各工艺条件下的膜污染状况,发现投加PAC降低了膜阻力,利于减缓膜污染.为了进一步研究相应的机理,采用空间排阻液相色谱(SELC)法对粉末炭投加前后膜污染物的分子量分布(MWD)进行了直接和间接的测定.结果表明,在MBR应用于微污染湖水处理时,小分子物质是一类重要的膜污染物质.PAC对大量小分子污染物(MW<3 000)的有效吸附去除是投加PAC后膜污染状况改善的重要原因.
【英文摘要】 In this experiment membrane bioreactor(MBR) and its hybrid process(MBR-PAC) were used to treat micro-polluted lake water.The influence of PAC addition on membrane fouling was investigated.It was found that PAC addition helped to reduce the membrane resistance and relieve membrane fouling.In order to understand its mechanism,steric exclusion liquid chromatogram(SELC) was applied to measure the molecular weight distribution(MWD) of membrane pollutants.Comparing the MWD analysis results of different processes ...
