| 摘 要： | 采用亚甲基兰法对已使用一段时间的活性炭滤料和新炭进行评价.试验结果表明:当用于处理微污染地表水时,长期运行后的煤质活性炭对亚甲基兰的吸附曲线的1/n值与新炭相比变化不大,果壳炭1/n值与煤质炭相差较大,活性炭微孔吸附竞争对有机物的吸附影响明显.煤质活性炭比果壳炭更适于处理北方地区微污染地表水,果壳炭则更适合作为生物滤料用于高负荷生物滤池.

| Abstract: | Methylene blue method was applied to evaluate the activated carbon media that had been used for some time and the new media.The results show that long-term continuous operation has little effect on the 1/n value of methylene adsorption curve by coal activated carbon for the treatment of micro-polluted surface water,difference of 1/n between pericarp carbon and coal activated carbon is obvious,and microporous adsorption competition of organic matter is significant.Coal activated carbon is fit for the treatme... |
