活性污泥法是将空气连续鼓入大量溶解有机污染物的废水中,经过一段时间的流动净化,在水中形成的絮凝体的污水法处理法。本文从活性污泥的概念,处理原理,好氧微生物种群等的角度出发,阐明了要使生活污水得到有效净化,关键在于具有足够能量和性能良好的活性污泥的培养和运用。 Activated sludge method is the continuous air into the air into a large number of dissolved organic pollutants in the waste water, after a period of flow purification, the formation of floc in the water treatment method. This article from the concept of activated sludge, treatment principle, aerobic microbial population point of view, to clarify the effective purification of domestic sewage, the key is to have sufficient energy and good performance of activated sludge culture and use.
