摘要:
从全流程角度出发，以北方常规净水工艺为例，通过中试探究了炭-砂与砂-炭滤池对冬季低温低浊水的净化效能，考察不同组合顺序下最终出水消毒副产物的生成情况。结果表明，相比于常规砂滤-活性炭滤池（炭池后置）工艺，活性炭滤池-砂滤池（炭池前置）工艺出水浊度降低，大粒径颗粒物减少了13.07%；炭池前置工艺对UV254和TOC的去除率分别提高了3.5%和2.7%；同时，炭池前置工艺消毒副产物的生成量低于炭池后置工艺。炭池前置工艺可强化滤池对低温低浊水中污染物的去除效能，可以作为提升北方地区水厂水质的一种手段。
Abstract:
This paper investigated the performances of conventional water purification processes in northern China (carbon-sand filter and sand-carbon filter) for purification of low temperature and turbidity water in a pilot experiment in winter, and analyzed the formation of disinfection by-products in the final effluent under different combination sequences from the perspective of the whole process. Compared with the conventional sand-activated carbon filter (carbon filter postposition), the turbidity of the effluent from activated carbon-sand filter (carbon filter preposition) was lower, and the particulates with large particle size were reduced by 13.07%, and the removal rates of UV254 and TOC were increased by 3.5% and 2.7%, respectively. In addition, the disinfection by-products yield of activated carbon-sand filter was lower than that of sand-activated carbon filter. The activated carbon-sand filter enhanced the removal rate of pollutants in low temperature and turbidity water. The results are meant to provide technical support for water quality improvement of waterworks in northern China.
