摘要
为了给南方某水厂筛选合适的活性炭,分别从碘吸附值、亚甲蓝吸附值、焦糖脱色率、吸附等温线、有机物及消毒副产物去除效果等方面对4种不同活性炭的吸附性能进行对比研究。结果表明,水厂现用的1^#炭虽然碘吸附值和亚甲蓝吸附值较大,微孔比例较高,但焦糖脱色率较低,而且对有机物和消毒副产物的去除效果不如芈炭好;4^#炭对TOC,UV254 ,CODm?和THMsFP的去除率分别为70.4%,80.9%,65. 0%和71.45%,优于其他3种炭。该水厂换炭时,建议选用4^#炭代替1^#炭,4^#炭对原水水质的适应性好,并且价格比1^#炭低,可为该水厂节省成本约1000万元。
The adsorption properties of four kinds of activated carbon were compared from the aspects of iodine adsorption value, methylene blue adsorption value, caramel decolorization rate, adsorption isotherm, and organics & disinfection by-products removal effect to select a suitable one for a water supply plant in south China. The results indicated that the No. 1 activated carbon had lower caramel decolorization rate and its removal effect of organic matter and disinfection by-products was not as good as that of No. 4 activated carbon, though the iodine adsorption value and methylene blue adsorption value of No. 1 activated carbon used in the water supply plant were larger with higher proportion of micropores. The removal rates of TOC, UV254 , CODMn, and THMsFP by No. 4 activated carbon were 70. 4%, 80. 9%, 65. 0% and 71. 45%, which were better than that of the other three types of activated carbon. Therefore, it is recommended to use No. 4 activated carbon to replace No. 1 activated carbon in the water supply plant. The No. 4 activated carbon has good adaptability to raw water quality, and the price is lower than No. 1 activated carbon, which can save about 10 million yuan for the water supply plant.
