• ( 3 ) the treatment result of no2 - n is good . when the influent concentration of no2 - n is 0 . 01 ~ 2 . 23mg / l , the effluent is less than o . lomg / l and the influence of temperature , hydraulic loading the total ratio of gas and water is small
  ( 3 )生物滤池对亚硝酸盐氮的去除效果比较好，试验期间，水源水中亚硝酸盐氮浓度范围为0 . 01 2 . 23mg / l ，出水浓度一般低于0 . 10mg / l ，水温、滤速、气水比对亚硝酸盐氮的去除无明显影响。
• Since the contamination of the original water , the pollutant in the water such as organic substance , ammonia nitrogen , algae toxin , finally nitrate , pelagic microbe and so on , whose concentration and species are becoming higher and more , deteriorate the quality of drinking water seriously
  由于水源受到污染，水中的有机物、氨氮和硝酸盐氮、藻类及毒素、浮游动物等污染物的含量和种类不断增多，严重影响了饮用水水质。
• 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
  回流比为2 : 1 ,水力负荷为2 . 55m3 / m2 ? h ,好氧柱气水比为3 : 1时试验表明:不同的c / n ( 1 . 05 7 . 45 )下,两级曝气生物滤池对有机物有很好的去除作用,出水有机物浓度小于7mg / l ,其中在缺氧柱进水端30cm内对有机物的去除最为明显;随着c / n的增加,系统出水氨氮浓度降低,当c / n为3 . 60时,出水氨氮浓度降到3 . 05mg / l ,已经满足回用水的氨氮标准; c / n < 3 . 60时,因为缺氧柱的不完全反硝化,体系中硝酸盐氮和亚硝酸盐氮发生积累影响了好氧柱的硝化反应使氨氮降解效果较差;系统对总氮的去除随着c / n的增加而增加,当c / n为3 . 60时,出水总氮已经降到11 . 18mg / l ,满足回用水的要求。
