摘要
通过动态试验，对自制载体的流化式生物膜法处理含酚废水的效能进行了重点考察．结果表明，当ＣＯＤ容积负荷达４．０ｋｇ／（ｍ３·ｄ）时，ＣＯＤ的去除率平均在８０％以上，酚去除率在９０％－１００％之间，出水ＣＯＤ和酚可达到排放标准。自制的载体挂膜快，膜厚适宜，易于流化。本处理系统抗冲击负荷能力强，具有较高的脱氢酶活性。
A dynamic experiment was conducted to examine the efficiency of the fluidized biofilm method with home-made carrier for treating phenolic wastewater.The experimental results have shown that COD and phenol were removed on an average over 80% and 90%-100%,respectively.while COD volumetric loading is 4.0 kg/(m3.d),and the final concentrations of COD and phenol in the effluent can meet Chinese Standard of Wastewater dischange permission.The biofilm can adhere quickly to the home-made carrier and the thickness of bio film is suitable to fluidize easily in the reactor.The treatment system can resist the loading fluctuation and possess high dehydrogenase activity.
