混凝-陶瓷膜组合工艺处理富营养化水体研究

Treatment of Eutrophic Water by the Combination of Coagulation and Ceramic Membrane

针对水体富营养化问题,提出一种混凝-陶瓷膜组合方法处理水体。结果表明,组合工艺最佳运行条件为:混凝剂PS-FZn投加量25mg/L,陶瓷膜操作压力0.09MPa;在进水流量为5L/h,水温30℃,连续运行40h,混凝-陶瓷膜组合工艺对富营养化水体中浊度、Chl-a、CODMn、TP、TN的去除率分别达到99.98%、99.35%、84.02%、75.31%和58.22%,对Chl-a去除显著,工艺运行稳定。

This paper proposed a coagulation-ceramic membrane treatment method for the eutrophication water. Tests showed that the coagulation was PSFZn, its dosage was 25mg/L, and the operating pressure of 0.09MPa. Under the combined technology treating, with influent flow of 5L/h, water temperature of 30℃, continuous running time of 40h, the turbidity, Chl-a, CODMn, TP, TN removals were 99.98%, 99.35%, 84.02%, 75.31% and 58.22% respectively. It has a good removal effect on Chl-a and the process is stable.
