摘要
探讨了含磷废水在添加不同药剂、不同试验条件下的的处理效率;研究表明:石灰法除磷在〔Ca2+/TP〕(摩尔比)为2:1时,pH值控制在10.0左右,TP的去除率达到96%以上;三氯化铁除磷时控制〔Fe3+/TP〕为2:1,pH值为7.0,TP的去除率能达到96%;硫酸亚铁与活性污泥协同除磷效果优于三氯化铁。
The processing efficiencies of phosphorus - containing effluent on different pharmacy and different test conditions were dicussed. Using chemical method to remove phosphorus proves that when [ Ca2+/TP) is 2 : 1, pH is about 10.0, the removal rate of TP is exceed 96%. When [ Fe3+/TP] is 2:1, pH is about 7.0, the removal rate of TP is also exceed 96%. The efficiency of FeSO4 cooridinating with activated sludge is better than that of FeCl3.
