| 摘 要： | 针对常规处理工艺难以解决东江原水发臭的问题，考察了高锰酸钾-粉末活性炭联用技术对水中嗅味的去除效果。结果表明，高锰酸钾一粉末活性炭联用对水中嗅味具有较好的去除效果，当氧化吸附时间为30min，高锰酸钾投加量为1．5mg/L，粉末活性炭投加量为40mg／L时，经混凝沉淀后水中的嗅味可由5级降至0级。此外，高锰酸钾和粉末活性炭联用对水中的有机物、浊度及锰也有明显的去除效果。

| Abstract: | In order to solve the serious issues of taste and odor which was difficult to treat with conventional process in Dongjiang River, the removal efficiencies with the method of potassium permanganate combined with powdered activated carbon （PAC） were investigated. The results showed that the treatment process of potassium permanganate combined with PAC was effective in removing taste and odor. The odor level was reduced from level 5 to 0 after coagulation and sedimentation when the oxidation adsorption time was 30 rain, the dosages of potassium permanganate and PAC were 1.5 mg/L and 40 mg/L respectively. In addition, the removal efficiencies of organics, turbidity and manganese were obvious with the process of potassium permanganate combined with PAC. |
