摘要
利用工业废弃物硫铁矿烧渣、结晶氯化铝、工业用水玻璃、工业盐酸为原材料配制聚硅氯化铝铁PSAFC ,并将其用于印染废水的处理 ,取得了良好的净水效果。结果表明 :处理印染废水的最佳pH值为 8～ 9;碱化度B为 1,印染废水的CODCr去除率达到 90
The industrial waste pyrite cinder,crystalline AlCl\-3,industrial water glass and industrial hydrochloric acid are used as raw materials to confect polysilicic acid aluminum ferric chloride (PSAFC).The PSAFC is then used as coagulant to treat printing and dyeing wastewater,with good purifying effects obtained.It is shown that the optimal conditions for treating printing and dyeing wastewater are under pH of 8～9 and basification degree( B ) of 1.The removal rate of COD Cr can reach over 90%.
