海藻酸钠混凝处理微污染水的研究

Study on Micro Polluted Water Treatment by Sodium Alginate Coagulation

本文以厦门大学嘉庚学院中区外河流内微污染湖水为处理对象,采用海藻酸钠混凝工艺对微污染水进行处理,研究海藻酸钠投加量和混凝时间对微污染水处理效果的影响,以色度、浊度和磷酸盐三项指标来判断海藻酸钠混凝的处理效果。结果表明,海藻酸钠投加量为1.33 mg/L时,色度和浊度的去除率分别达到65%、64%,该工艺对微污染水的处理效果较好。

In this paper,the micro polluted lake water in the rivers outside the central area of Xiamen University Tan Kah Kee College was treated by sodium alginate coagulation process,and the influence of sodium alginate dosage and coagulation time on the treatment effect of micro polluted water was studied,and the treatment effect of sodium alginate coagulation was judged by three indexes of chroma,turbidity and phosphate.The results showed that when the dosage of sodium alginate was 1.33 mg/L,the removal rates of color and turbidity reached 65%and 64%,respectively,and this process has a better treatment effect on micro-polluted water.
