摘要：合成了聚环氧琥珀酸-聚硅酸铁锌复配物(PESA-PSFZ),并对其稳定性和絮凝效果进行了研究。结果表明:PESA-PSFZ较聚环氧琥珀酸-聚硅酸复配物具有更高的Zeta电位及更好的去浊效果,沉降速率快,适用的pH范围广;当PESA-PSFZ加入量为6mg/L时,对模拟废水的浊度去除率达99.2%;当PESA-PSFZ加入量为20mg/L时,对印染废水的COD去除率达87.3%。
The composite flocculant, polyepoxysuccinic acid-polysilicate ferric zinc （PESA-PSFZ）, was synthesized and its stability and flocculating effect were examined. The results show that： Comparing with polyepoxysuccinic acid-polysilicic acid, PESA-PSFZ has a higher Zeta-potential, a better turbidity removal effect, a faster sedimentation velocity and a wider application pH range; When the dosage of PESA-PSFZ is 6 mg/L, the turbidity removal rate of simulated wastewater is 99.2% ; When the dosage of PESA-PSFZ is 20 mg/L, the COD removal rate of printing and dyeing wastewater is 87.3%.
