influent side meaning in English

进料的一侧

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 % 。
