复合型絮凝剂处理油墨废水的研究
|
摘要
以3-氯2-羟丙基三甲基氯化铵(CHPTMAC)、玉米淀粉、AlCl_3、Al_2(SO_4)_3、PAC、FeSO_4、FeCl_3等无机絮凝剂为原料制备出一种有机无机复合型絮凝剂(PMSF),并用于福建某油墨生产企业,系统考察了其对油墨废水进行处理时的最优条件。试验发现,PMSF对油墨废水有很强的絮凝和脱色效果,废水的COD去除率可达到86.8%,色度去除率可达到94.6%。对比试验结果表明,PMSF处理油墨废水的絮凝综合性能明显优于季铵化淀粉絮凝剂(MSF)。
An organic and inorganic compound flocculant, denoted as PMSF, was prepared by adopting CHPTMAC, corn starch, AlCl_3, Al_2(SO_4)_3, PAC, FeSO_4 and FeCl_3. PMSF was used to pretreat ink wastewater from a ink production enterprises in Fuzhou. The flocculation conditions were optimized, and results indicated that PMSF showed excellent performance on treatment of ink wastewater, with CODCr removal efficiency up to 86.8%, decoloring rate up to 94.8%. Comparison experiments indicated that flocculation performance of PMSF prevailed over MSF evidently.
