pre-ozonation 中文意思是什麼
-
( 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 ）通過對預臭氧化的生產試驗，水溫較高的情況下，溶解氧容易達到飽和，甚至是過飽和狀態，這樣容易在濾池產生氣阻現象，濾池的工作周期從三十六小時縮短到十幾小時，影響水廠的正常運轉。因此建議不單獨投加預臭氧。 -
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
得出如下結論： （ 1 ）最優化的深度處理飲用水的工藝應該是「常規處理+臭氧化+生物活性炭」 ，如果投加預臭氧，對微污染水源水中的氨氮沒有效果，反而引起預氧化出水的濁度升高，但是對滅菌除藻，控制微生物的生長有一定的作用。
