| 摘 要： | 针对郑州市S水厂原水二甲基异莰醇(2-MIB)季节性升高问题,采用在原水中投加粉末活性炭(PAC)或二氧化氯(ClO2)的应急处理技术。结果表明,在原水泵站投加PAC可以有效控制水体的臭味;与单层石英砂滤层相比,石英砂加活性炭滤层对2-MIB的去除率可增加56%;为防止活性炭吸附效率降低,应避免PAC与ClO2同时使用。

| Abstract: | Aimed at the issues of seasonal higher of 2-MIB in raw water of Zhengzhou S Waterworks, emergent treatment technology of dosing powdered activated carbon （ PAC ） or ClO2 in raw water was adopted. The results showed that the odour of water could be controlled by dosing PAC in raw water pump station, and the removal rate of 2-MIB with quartz sand and PAC filter media could be increased 56% compared with single-layer quartz sand filter media. Usage of PAC and ClO2 at the same time should be avoided in order to prevent the decrease of adsorption efficiency of PAC. |
