摘要
利用正交试验方法对印染废水的混凝处理最佳试验条件进行了研究。通过聚合氯化铝铁(PAFC)和磷酸氢二钠(NaH2PO4·2H2O)对模拟印染废水处理效果的研究表明,在溶液pH为7、PAFC与NaH2PO4·2H2O投加量比为3∶2、温度为55℃、搅拌时间为15min时,对模拟印染废水处理得到较为满意的效果,COD的去除率为80.45%,经处理后水的吸光度为0.4269。
The conditions of dyeing wastewater coagulation were optimized by orthogonal test method. The study of simulated dyeing wastewater treatment by polymeric aluminum ferric chloride (PAFC) and disodium hydrogen phosphate ( NaH2PO4 -2H2O) showed that under the conditions of pH 7, dosing ratio of PAFC and NaH2PO4·2H2O 3 : 2, 55℃ and stirring 15rain, COD removal rate of 80.45% and treated water absorbance of 0. 4269 were achieved.
