• 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 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。
• Under the permitted conditions , the all - scale plant was made to pre - ozonation . the results showed : ( l ) the optimal advanced purification drinking water process should be " regular treatment + ozonation + biological activated carbon " . though pre - ozonation had no effects on ammonia nitrogen in the water of micro - pollution water source , instead the turbidity of pre - oxidation finished water was raised , it had effects on killing bacteria and removing algae , and controlling the growth of micro - organism
  得出如下结论： ( 1 )最优化的深度处理饮用水的工艺应该是“常规处理+臭氧化+生物活性炭” ，如果投加预臭氧，对微污染水源水中的氨氮没有效果，反而引起预氧化出水的浊度升高，但是对灭菌除藻，控制微生物的生长有一定的作用。
• Water pollution was becoming intensified , while with the improvement of human ' s living standard , more attention was increasingly paid to the sanitation and safety of drinking water . so adopting advanced drinking water purification to obtain high quality water was necessary . by changing the different combination of drinking water ' s regular treatment process , ozonation , activated carbon and biological activated carbon , the paper chose the optimal treatment process , also the parameters of the process were analyzed through experiments , then the economic , reasonable process parameters were determined
  水污染不断在加剧，而随着人们生活水平的提高，饮用水的卫生和安全越来越被关注，因此有必要采用先进的饮用水深度处理技术来获得优质饮用水，本文通过改变饮用水常规处理工艺、臭氧化、活性炭与生物活性炭的不同组合的中试试验研究，选择出了最佳处理工艺，又对最佳处理工艺的各个参数进行试验分析，确定出经济合理的工艺参数，在现有的条件下，对预臭氧化进行了生产试验。
• ( 6 ) by the all - scale plant of the pre - ozonation experiment , when the water temperature is high , the dissolved oxygen could easily attain saturation , even over - saturation , then the phenomenon of air block could be caused in the tank , the working period of tank may shorten from 36 hours to less than 15 hours , it would influence the normal operation of water treatment plant , so it was suggested not use pre - ozonation only
  ( 6 )通过对预臭氧化的生产试验，水温较高的情况下，溶解氧容易达到饱和，甚至是过饱和状态，这样容易在滤池产生气阻现象，滤池的工作周期从三十六小时缩短到十几小时，影响水厂的正常运转。因此建议不单独投加预臭氧。
