摘要
利用盐酸酸洗废液制备聚合硅酸氯化铝铁(PSAFC),并用PSAFC处理造纸脱墨废水,考察了各种因素对絮凝效果的影响。实验结果表明:在废水pH为6、PSAFC加入量为240mg/L、搅拌转速为150r/min、搅拌时间为2min,静置时间为25min的条件下,COD、浊度、色度的去除率分别为87.2%,99.2%,94.5%;PSAFC的絮凝效果明显好于市售的聚合氯化铝和聚合氯化铁。
Polysilicate aluminum ferric chloride （PSAFC） was prepared from waste pickling liquor containing hydrochloric acid. The wastewater from waste paper deinking was treated using PSAFC and the factors affecting the flocculating effect were investigated. Under the conditions of wastewater pH 6, PSAFC dosage 240 mg/L, stirring speed 150 r/min, stirring time 2 rain and standing time 25 min, the removal rates of COD, turbidity and chroma are 87.2%, 99.2% and 94. 5% respectively. The flocculating effect of PSAFC is much better than those of PAC and PFC on sale.
