| 摘 要： | 针对耒阳电厂粉煤灰和中药厂排出废水的特点,考查了粉煤灰的投加量、颗粒度、改性剂、搅拌吸附时间和pH值等因素对处理效果的影响.用改性后的粉煤灰进行了L9(34)正交实验,根据实验结果,确定了适合的条件为:每升废水中投加粉煤灰90 g,在pH值=7.5时搅拌45min,沉淀35min.在此实验条件下,CODCr,色度,浊度的去除率分别为84.2%,83.2%,79.2%.

| Abstract: | Several effect factors, such as the dosing quantity, fly-ash granularity, modified reagent, stirring time and pH have been investigated on the treatment efficiency according to the feature of fly-ash from Leiyang power plant and the chinese traditional medicine plant effluent. We have got the optimal conditions of dosing quantity of 90 g/L modified fly-ash, stirring time of 45 minutes, at pH=7.5 and 35 minutes sedimentation by L9 (34)orthogonal experiments. The removed rate of CODCr, colourity degree and tu... |
