| 摘 要： | 通过絮凝实验考察了自制疏水改性缔合聚合物(Hydrophob ically Mod ified Polym er,简称HPAM)的除油效果,对其絮凝机理进行了探讨,测试了pH值及NaC l浓度对其絮凝效果的影响,由此确定了最佳絮凝条件。研究结果表明,HPAM对于模拟含油废水在pH值为9时,加药量为0.2 mg/L的条件下絮凝效果最佳;HPAM随着盐浓度的升高,黏度增大且絮凝效果提高,表明HPAM以疏水缔合作用为主,具有较好的抗盐性。

| Abstract: | Effect of oil removal of hydrophobically modified polymer(HPAM)under the conditions of different NaCl concentration and pH has been investigated,then,got the optimum condition in the experiment.And the mechanism of flocculation was discussed.For simulated oil-in-water wastewater,it was found that the optimal effect was obtained under the condition(pH:9,dosage:0.2 mg/L);Effect of flocculation was improved with raising concentration of NaCl.Flocculation occurred mainly through the effect of hydrophobic association. |
