氯化铝%含磷废水%化学沉淀法
氯化鋁%含燐廢水%化學沉澱法
록화려%함린폐수%화학침정법
AlCl3%phosphorus-containing wastewater%chemical precipitation
磷的生物法去除很难达到污水排放标准,通常要结合化学絮凝的方法。因此,试验采用氯化铝对含磷废水进行处理,考察了氯化铝投加量、凝聚转速、搅拌时间、溶液pH值等因素对除磷效果的影响。结果表明,在一定条件下,磷去除效果较好,去除率可达94%。
燐的生物法去除很難達到汙水排放標準,通常要結閤化學絮凝的方法。因此,試驗採用氯化鋁對含燐廢水進行處理,攷察瞭氯化鋁投加量、凝聚轉速、攪拌時間、溶液pH值等因素對除燐效果的影響。結果錶明,在一定條件下,燐去除效果較好,去除率可達94%。

Biological process of phosphorus removal from waste water can hardly satisfy the national regulation,so the water still needed chemical precipitation.The treatment of wastewater containing phosphorous by AlCl3 was studied.The effects of AlCl3 dose,coagulation strirring speed,stirring time and pH value were investigated.The results showed that the removal rate reacheded 94% under some conditions.
