| 1. | 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 | | 2. | 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。 | | 3. | Gas chromatography - mass spectrometry ( gc - ms ) analyses showed that both potassium permanganate and chlorine could oxidate the organic matters with unsaturated functional groups into those with carboxyl , hydroxyl and aldehyde . and it was further revealed that after preoxidation by potassium permanganate , the sorts of organic matters were reduced remarkably , however , chlorination leaded to increase of the sorts of orgnic matters and brought some chloro - organics such as chlorobenzene , chlorophenol , and trichloro - ethane
通过色谱-质谱联用( gc - ms )评价分析了高锰酸钾和氯对有机物结构的改变，高锰酸钾和氯均将原水中的一些不饱和性有机物氧化分解为一些含氧基团的有机物，如羧酸类、醇类和醛等有机物，但预氯化会在水中出现一些卤代物，卤代产物不仅出现在苯环上，而且出现在链烃上。 | | 4. | The result of experiment shows : the combined process of composite potassium permanganate and powder activated carbon has excellent efficiency of enhanced coagulation and is more advanced than pre - chlorination , which can completely replace pre - chlorination and is not only feasible in technology but also remarkable in economic benefit
试验研究结果表明：高锰酸钾复合药剂与粉末活性炭联用具有优异的强化混凝效能，能够完全取代预氯化并获得比其更佳的混凝效果；该项强化混凝工艺不仅技术上可行，而且具有明显的经济效益。 | | 5. | 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 。 | | 6. | The effects of potassium permanganate , chorine and ozone were compared and the results showed that although all of them could enhance coagulation and then reduce the turbidity of the water after subsequent treatment units , potassium permanganate and ozone were more effective to ensure the quality of the water after air - flotation and sand - filtration
对高锰酸钾、氯和臭氧三种氧化剂进行分析比较，结果表明三种氧化剂均能提高混凝效果，但高锰酸钾预氧化和预臭氧化在提高气浮和过滤出水水质保障率方面均优于预氯化。 | | 7. | In light of various pollution situations and various water treatment processes of two water factories , better solved the problems about throwing doses , throwing localities , throwing forms of composite potassium permanganate and powder activated carbon , as well as compared the enhanced coagulation efficacy of combined process of composite potassium permanganate and powder activated carbon , composite potassium permanganate pre - oxidation and pre - chlorination
针对两水厂不同的源水污染状况和现有的水处理工艺，通过室内和生产性试验，很好地解决了高锰酸钾复合药剂、粉末活性炭最佳投加点、投加量和投加方式的确定问题，并对两者联用的强化混凝效果与预氯化、单独高锰酸钾复合药剂预氧化进行了对比。 |
