【摘要】 本文介绍应用吉林大学新近研制的玉米淀粉接枝磺甲基化聚丙烯酰胺共聚物,(以下简称为接枝物)作为絮凝剂,对工业企业排放的含汞污水絮凝沉降的处理效果。实验数据表明,采用该接枝共聚物作为混凝剂,处理含汞污水,其处理效率可达到99％以上,处理后的水基本上达到了国家规定的排放标准。同时,对最佳投药量,量佳沉淀时间及最佳pH值等进行了研究。更多还原

【Abstract】 Studies on the flocculation and precipitation effect of maize starch soin S-M-G-PAAM for mercury wastewater were reported . More than 99% of Hg were removed from wastewater by this reagent .Optimum reagent quantity, optimum precipitation time and optimum pH range for the flooculation, were studied.更多还原
