| 摘 要： | 粉末活性炭去除水中有机物的效果受水的pH影响较大。降低水的pH,可显著提高粉末活性炭去除有机物的效果。对于黄浦江水,当pH为5.5,粉末活性炭投加量为40mg/L时,DOC和UV_(254)的去除率分别达到43.8％和36.2％。

| Abstract: | The pH effect on the removal of organic substance from raw water by powdered activated carbon (PAC) is investigated. The decreased pH could remove organics more effectively. For the Huangpu River water, at PAC 40 mg/L and pH 5.5, the optimum removal rates of DOC and UV_(254) are 43.8% and 36.2% respectively. |

| Keywords: | Powdered activated carbon Optimal pH Removal rate of organic substance |
