| 摘 要： | 文章以GAC强化砂滤池中试试验为基础,研究GAC强化砂滤池如何完善普通砂滤池对有机物和"三氮"的去除效果。实验结果表明:GAC强化砂滤池对浊度的平均去除率为92.78%;对高锰酸盐指数的平均去除率为15.67%;GAC强化砂滤池滤后水与待滤水相比,氨氮含量减少69.15%,亚硝酸盐氮增加93.08倍,硝酸盐氮增加16.54%。由此可见,GAC强化砂滤池的生物作用要明显优于普通砂滤池。

| Abstract: | This paper describes a pilot experiment conducted in a waterworks with a purpose to purify organic micro-contaminated raw water,focusing on the sand-filter enhanced by granular activated carbon(GAC) in place of the conventional one,which is supposed to be able to improve the removals of organic compounds and the relevant pollutants such as NH4+-N,NO2--N and NO3--N. |
