| 摘 要： | 通过对三种组成差别较大的粉煤灰(FA)的吸附性能实验,筛选出适宜作微生物吸附载体的FA.根据污水处理系统的MLSS量选定FA投加量为2 g/L.加入粉煤灰的活性污泥处理系统,污泥絮体大,沉降速率明显提高;污水处理系统运行稳定;对CODcr的去除率为87%,对氨氮的去除率为82%,相对于未加粉煤灰的活性污泥系统有所提高.

| Abstract: | The optimum fly ash(FA) to carry microbe was screened out through the adsorbability experiment of three kinds of fly ashes,in which the compositions vary largely.According to the MLSS quantity of sewage treatment system,the dosage of FA was 2 g/L.After the FA was added to activated sludge processing system,the cubage of sludge flocculent augmented,sedimentation rate increased evidently and the sewage treatment system worked stably.The removal rate of CODcr was 87% and the removal rate of NH3-N was 82%,which was increased compared to those of activated sludge processing system without FA. |
