【摘要】 通过烧杯实验,研究了用壳聚糖-聚丙烯酰胺(PAM)絮凝法处理成分复杂、脱色困难的钻井废水的方法和条件。该方法的絮凝脱色效果明显优于常规的无机-有机复配混凝法和PAM-活性炭吸附法,并且试剂用量少,沉降时间短,操作简便。更多还原

【Abstract】 The conditions of treating drilling wastewater with complex composition and hard decoloration were studied using chitosan-polyacrylamide(PAM) coagulation method by beaker experiment.It was more effective that the drilling wastewater was treated using chitosan-PAM coagulation method compared with ordinary inorganic-organic mixture coagulation or PAM-active carbon absorption method.Chitosan-PAM coagulation method had also good point as follows:low consumption,short coagulation time,and easy operation.更多还原
