摘要
采用传统两相厌氧工艺与膜分离技术相结合的系统（ＭＢＳ）处理有机废水的研究结果表明：系统ＣＯＤ去除率达到９５％，ＳＳ去除率在９２％以上，酸化率为６０％—８０％，气化率在８０％—９０％左右，产酸反应器出水酸化水平高，低分子有机酸含量高，使两相工艺分相较为完全．探讨了ＭＢＳ系统的运行特点和引入膜的作用，分析表明：ＭＢＳ系统从总体上优于两相厌氧生物系统（ＢＳ）．
The study utilizes the process combined conventional two phase anaerobic biosystem with membrane separation(MBS)to treat organic wastewater.In the system,COD removal is above 95%,SS removal is above 92%,acidification rate is 70%—80%,and gasidification efficiency is 80%—90%.The article inquire into the operation features of MBS and the effect of membrane introduced,and discusses the quality of biological phase in methane production phase of MBS.It also compares the operation of MBS with conventional two phase anaerobic biosystem(BS),and makes a conclusion that MBS is superior to BS in the whole.
