磁混凝处理城市污水处理厂尾水工艺优化研究

磁混凝作为一种新型的水处理工艺,以其高效分离净水的方法在水与废水处理领域的地位不断突出,并引起了广泛的关注。以COD、总磷、浊度的去除率为指标,比较常规混凝和磁混凝对污水处理厂尾水污染物的去除效果。实验结果显示,磁混凝对尾水水样中COD、总磷、浊度的去除率分别达到了92.6%,92.3%,89.7%。采用磁混凝方法处理污水处理厂尾水,提高了混凝效果,同时缩短了絮凝和沉降的时间。

As a new type of water treatment technology,magnetic coagulation has been widely concerned in the field of water and wastewater treatment with its high efficient separation of water purification method. With the removal rate of COD,total phosphorus and turbidity as index,compare the effects of conventional coagulation and magnetic coagulation on removal of pollutants. The experimental results showed that the removal rate of COD,total phosphorus and turbidity of the water samples reached 92.6%,92.3%,89.7% respectively. Disposal of sewage treatment plant effluent by using the magnetic coagulation method improves the coagulation effect and shortens the time of flocculation and settling.
