摘要
对壳聚糖和碱铝复配应用于炼油活性污泥的处理效果进行了研究 ,并与GD - 1 1 2 (主要成分为聚丙烯酰胺 )、碱铝的复配进行了比较。结果表明 ,壳聚糖和碱铝复配后作为活性污泥絮凝剂 ,投加量为壳聚糖 1 .6 7mg/l、碱铝 1 0mg/l时 ,即有很好的效果 ,pH值适用范围为 6～ 7。在活性污泥pH值为7(自然值 )时 ,壳聚糖、碱铝复配与GD - 1 1 2。
The chitosan was applied to treat petrochemical sludges in combination with poly aluminum chloride(PAC).The flocculation efficiency of chitosan in combination with PAC had been studied. The results showed that the optimum flocculation condition of the compound flocculant is that pH value in activated sludge 6～7, the concentration of compound flocculant chitosan and PAC 1.67mg/L and 10mg/L, respectively, and the flocculation effect was equivalence to that of PAM in combination with PAC.
