prechlorination meaning in English
预加氯处理
预氯化
Examples
- The effect of prechlorination on powdered activated carbon for removing odor
预氯化对粉末活性炭除嗅的影响 - However , although prechlorination efficiently removed algae , its effect was directly related to the quantity of algae and was more obvious in the period of algae bloom . with regard to yellow river water in winter with low temperature and low turbidity , it was discovered that preozonation did not result in a substantial removal of total organic carbon ( toc ) , but a remarkable uv254 . it was further revealed that preozonation changed the characteristics and structure of organic matters and then enhanced removal efficiencie s of them by subsequent processes
对于夏季高藻期水质，高锰酸钾预氧化对有机物有一定的去除能力，并能提高后续工艺出水水质；预氯化能显著去除藻类，但后续工艺出水水质受藻类数量影响明显，预氯化只有在高藻期才能提高后续常规处理工艺出水水质；对于冬季低温低浊水，预臭氧化虽不能降低水中有机物浓度，但能显著提高后续常规处理单元出水水质。 - The enzyme - linked immunosorbent assay ( elisa ) and high performance liquid chro - matography ( hplc ) analysis for detection of mc were optimized . the removal rates of mc by conventional water treatment processes were investigated through the laboratory study and the detection of mc in every process in meiyuan drinking water treatment plant . results showed that the prechlorination of eutrophic water led to the release of intracellular toxins to water phase
本文完善了mc的elisa和hplc分析方法，通过模拟试验及水厂实测调查了富营养化太湖水中mc在常规净水工艺中的去除特性，结果表明预氯化使藻细胞内的mc释放出来，混凝沉淀对细胞外mc无去除作用，砂滤可去除17 . 2 40 . 4的细胞外mc和19 . 0 36 . 6的总mc ，加氯消毒对细胞外mc和总mc的去除率分别为30 45 . 3和30 51 . 7 。
