Pilot-Scale Study on Advanced Treatment of Danjiangkou Reservoir Water by Biological Activated Carbon Process

  • 摘要: 活性炭过滤是饮用水深度处理的重要工艺,其中滤速、炭层高度、温度和炭龄是影响活性炭滤池运行效果的关键因素. 以丹江口水库水为处理对象,以混凝-沉淀-砂滤出水作为炭滤池进水,以高锰酸盐指数和UV254去除率为评价指标,考察2011年4月—2013年5月取自北京某水厂的新炭、1年炭、3年炭和5年炭(2011年5月时炭龄)对水中有机物的去除效果. 结果表明,随着滤速的增大,有机物去除率降低;活性炭炭柱滤速为8 m/h时,高锰酸盐指数和UV254去除率分别为41.9%和41.2%,能够获得较好的处理效果. UV254去除率随总炭层高度的增大而增大. 随着炭层高度的增加,单位高度活性炭滤料对UV254的去除率降低.夏季高温期,1年炭对高锰酸盐指数和UV254的去除率分别为44.2%~57.4%和38.5%~53.1%,高于其在冬季低温期的去除率(38.9%~51.1%和31.7%~45.5%). 活性炭在使用初期,主要依靠吸附作用去除有机物;随着使用年限的增长,活性炭的生物载体作用日益明显,生物作用占主导地位,炭龄对有机物去除效果的影响变小,不同炭龄活性炭的处理效果差异不大,可适当延长活性炭的使用年限,降低处理成本.
