- Example Sentences:
| 1. | ( 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。 | | 2. | The height of media 、 the ratio of gas to liquid 、 hydraulic loading 、 the organic and ammonia loading of influent are the key factors influence the performance of one - stage aerobic baf . the conclusions of the experiment are as following : the best height to remove the organic matter and ammonia is at 60cm 、 120cm from the influent side respectively . the best ratio of gas to liquid is 3 : 1 4 : 1 ; the organic and ammonia loading of influent have litlle influence on the performance of one - stage aerobic baf when the concentration are low ; whe the ratio of gas to liquid is 3 : 1 , the ammonia loading is blow 0 . 87kgnh _ 4 ~ + - n / m ~ 3 . d , the enfluent concentration of ammonia is blow 5mg / l which satisfies the water reuse standard ; at different organic loadings , the removal of organic matter keeps 35 % 45 % . hypothermia is unfavourable to nitrification for one - stage aerobic baf to removel ammonia , the influent concentration of ammonia can ’ t satisfy the water reuse standard 试验表明:对有机物的去除主要发生在进水端60cm内,对氨氮的去除主要发生在进水端120cm内;曝气生物滤池运行的最佳气水比为3 : 1 4 : 1 ;在进水有机物和氨氮浓度比较小时,水力负荷对其去除率影响不大;在气水比为3 : 1 ,进水氨氮负荷小于0 . 87kgnh4 + - n / m3 (滤料) ? d时,出水氨氮小于5mg / l ,满足回用水的要求;在不同有机负荷下,有机物去除率保持在35 % 45 % 。 | | 3. | Based on advanced technology , this thesis bring forward the optimal scheme and set down general system - drawings and flow charts . using step7 - micro software , we achieve the auto - control aim in drinking water treatment . in practice , the complexity and non - linaerity exit in the system of water treatment , so we apply fuzzy control in water treatment and design a kind of controller which structure can be altered according to the using - rate of ozone and the variety of water quality 实际饮用水处理系统由于存在复杂性、非线性、时变性,本文根据臭氧生物活性炭水处理工艺存在复杂性、非线性、时变性等特点,将模糊控制应用在水处理这一不确定的非线性时变系统,针对不同水温下臭氧利用率及水质的变化,设计一种基于系统过程状态的变结构的模糊控制器,以单片机作为主要控制硬件,按查表方式设计软件,对进水阀门开度进行在线控制,调节臭氧气体与进水的比例(臭氧流量及浓度不变) ,达到气水比最优化。 | | 4. | 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。 |
