新型高分子絮凝剂处理含油废水的研究

A New Macromolecular Flocculant in the Treatment of Oily Wastewater in Oilfields

利用新型高分子絮凝剂聚酰胺胺类 (polyam idoam ine PAMAM)树形分子对油田含油废水处理进行研究 .研究表明 :该絮凝剂在用量非常低的情况下 (15～ 2 0 m g· L- 1 ) ,除油效果明显 ,废水含油量从处理前 32 0 m g· L- 1降至处理后 1mg· L- 1 ;该絮凝剂与天然高分子助凝剂 (可溶性淀粉、羧甲基纤维素等 )配合使用效果更好 ,用量可降低到 5 mg· L- 1 .

Studies oily wastewater treatment in oilfields using polyamidoamine(PAMAM), a new type polymeric dendrimer flocculant. The results revealed that when used in minute amounts (15～20 mg·L -1 ) it could very effectively decrease the oil content, from 320 mg·L -1 to 1 mg·L -1 . Combining PAMAM with some natural polymer coagulator such as soluble starch or carboxyl methyl cellulose in the treatment of oily wastewater, the effect of removal could even be better than that of PAMAM alone, and the amount of PAMAM could be reduced to 5 mg·L -1 .
