決不允許為了吹除雜質從高壓氣源，例如氣瓶中放出氫氣。做類似事情時，只能用氮氣或空氣作為外在氣源。Putting the potassium permanganate into the filter can improve its effect, the removal of organics and ammonia is increased, the influent concentration can satisfy the water reuse standard. but the turbidity of influent is unsatisfactory. the c / n ratio is the key factor to influence the nitrogen - removal of the anoxic / aerobic two - stage baf when the reflux ratio 、 hydraulic loading and the ratio of gas to liquid in aerobic filter are fixed. the anoxic / aerobic two - stage baf has a good removal of organics at different c / n ratio when the reflux ratio is 2, hydraulic loading is 2. 55m ~ 3 / m ~ 2 ? h and the ratio of gas to liquid in aerobic filter is 3 : 1. the influent concentration of organics is blow 7mg / l. from the beginning to 30cm of the anoxic filter, the removal of the organics is significant ; as the c / n ratio increasing, the influent concentration of ammonia is decreasing. when the c / n ratio is 3. 60, the enfluent concentration of ammonia is 3. 05mg / l which satisfies the water reuse standard. when the c / n ration is less than 3. 60, because of the imperfection
迴流比為2 : 1 ，水力負荷為2 . 55m3 / m2 ? h ，好氧柱氣水比為3 : 1時試驗表明:不同的c / n （ 1 . 05 7 . 45 ）下，兩級曝氣生物濾池對有機物有很好的去除作用，出水有機物濃度小於7mg / l ，其中在缺氧柱進水端30cm內對有機物的去除最為明顯;隨著c / n的增加，系統出水氨氮濃度降低，當c / n為3 . 60時，出水氨氮濃度降到3 . 05mg / l ，已經滿足回用水的氨氮標準; c / n < 3 . 60時，因為缺氧柱的不完全反硝化，體系中硝酸鹽氮和亞硝酸鹽氮發生積累影響了好氧柱的硝化反應使氨氮降解效果較差;系統對總氮的去除隨著c / n的增加而增加，當c / n為3 . 60時，出水總氮已經降到11 . 18mg / l ，滿足回用水的要求。N sources ( including organic and inorganic n tested ) and c sources tested could restrain methane oxidation. cellulose inhibited methane oxidation most weakly while the high concentration of methanol and glucose did dramatically, but the proper concentration of methanol could stimulate soil methane oxidation sharply. in the middle process of methane oxidation, addition of glucose could restrain methane oxidation shortly but the inhibition could be relieved about 5 days later when supplied again with enough oxygen
土壤微生物是甲烷氧化的主要生物類群，含水量對土壤甲烷氧化活性有明顯影響，過高或過低對甲烷氧化均具有抑制作用；氮源（包括有機和無機氮源）對甲烷氧化均有抑制作用；不同碳源對甲烷氧化的影響各異，纖維素對甲烷氧化抑制作用最小，而高濃度的甲醇、葡萄糖則對甲烷氧化具有強烈抑制作用；而適當濃度的甲醇可極大促進土壤對甲烷的氧化：在甲烷氧化過程中加入葡萄糖能迅速抑制甲烷氧化；在加入葡萄糖的同時保持瓶中充足的氧氣，則這種抑制作用可以在重新培養一定時間后得到解除。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。The mechanism of biological denitrification and phosphorus removal is briefly analyzed in this paper, and several effective and practical processes are also introduced
