南方某水厂更换活性炭后试运行阶段性能研究

Study on the performance of a waterworks after replacing activated carbon in south China

对某水厂一座运行中的炭滤池更换活性炭,在调试工作结束后持续监测出水指标。结果表明,与同期运行的旧炭滤池相比,更换为具有更高碘吸附值和亚甲基蓝值的新活性炭的滤池出水有机污染物浓度更低,pH略高,浊度则相当。在持续的监测周期内,经调试后的新炭滤池出水水质达标并能保持在较为稳定的水平。

The activated carbon of a running carbon filter in a waterworks was replaced,and theeffluent indicators were continuously monitored after the commissioning work was completed.The resultsshowed that the concentration of organic contaminants was lower in the effluent of the filter with newactivated carbon which had higher iodine adsorption value and methylene blue value,the pH was slightlyhigher,and the turbidity was the same.In the continuous monitoring period,the effluent quality of thenew carbon filter after debugging could reach the standard and maintain at a relatively stable level.
