羧甲基壳聚糖的制备及絮凝性能探讨

Preparation and discussion of flocculating capability about carboxymethylated chitosan

制备了具有水溶性、无毒羧甲基壳聚糖 (以下简称 N OCC) ,将其作为絮凝剂与聚丙烯酰胺 ( PA M)一道处理生活污水 ,通过测定其沉降时间、沉降絮体高度、沉降速度、沉降后溶液透光率等参数 ,表征了其絮凝能力 ,提出了普遍认为聚丙烯酰胺处理一般污水具有良好絮凝能力的不同看法 。

The water\|soluble,non\|toxic carboxymethylated chitosan was made and the polypropylene acylamide, carboxymethylated chitosan were used to treat the living wastewater togeter.Their flocculating capability were described by sedimentary time , heigt of the sedimented volume and solution transmittancy.Meanwile the different opinion was suggested,which the polypropylene acylamide has better flocculating ability to treat genaral wastewater.Some beneficial investgation were provided for the usage and exploitation of chitosan.
