不同颗粒活性炭去除微污染水中有机物的性能研究

Removal of Organics by Different GACs in Micro-Polluted Raw Water

随着饮用水水质标准的不断提高,颗粒活性炭在水净化工艺中得到了广泛关注。选用不同类型的颗粒活性炭对去除微污染水中有机物的性能进行了研究。首先,通过静态吸附实验筛选出合适的活性炭炭种;然后,通过动态吸附实验考察了该活性炭在不同滤速下对于原水中COD_(Mn)、UV_(254)及浊度的去除特性。结果表明山西的煤质颗粒活性炭在滤速15.59 m/h时去除效果显著。

Using GAC （granular activated carbon） in the technology of water purification is concerned widely with the improvement of drinking water quality standard. A series of experiments, which using several different kinds of GAC to remove the organic matter in mi- cro-polluted water related. Firstly, the proper GAC was selected through static adsorption experiment. Then, the removal of turbidity, CODMn and UV254 at different filtration velocity were discussed. The result showed GAC produced by Shanxi had the highest absorption ca- pacity at the filtration velocity of 15.59 m/h.
