摘要
对壳聚糖用于活性污泥絮凝沉降的ｐＨ值适用范围、投加浓度进行了研究，并与常规絮凝剂聚丙烯酰胺（ＰＡＭ）和聚合氯化铝（ＰＡＣ）进行了比较。结果表明，壳聚糖作为活性污泥絮凝剂，投加量为３ｍｇ／Ｌ时，即有很好效果，ｐＨ值适用范围为５～８，ｐＨ６为最佳值。在活性污泥ｐＨ７．６（自然值），壳聚糖与阳离子聚丙烯酰胺在实验浓度范围内效果基本相当，且优于２０ｍｇ／Ｌ聚合氯化铝。
The flocculation efficiency of chitosan has been studied.The results showed that the optimum flocculation condition of chitosan are: pH in actived sludge is 5-8; the concentration of chitosan is equivalence to that of PAM, better than the PAC in the flocculation of actived sludge.
