baf 中文意思是什麼

Baf has many advantages, such as small volume, little covering earth and hydraulic retention time ( hrt ), high treatment efficiency and effluent water quality, low investment and running cost etc. baf has been used widely for many years in the world and been used to treat several wastewater in our country. in this paper, baf was studied on guanting reservoir water source treatment with pilot scale and homemade expanded clay as filtration media

曝氣生物濾池（ biologicalaeratedfilter ，簡稱baf ，或biologicalfiltrationoxidizationreactor ，簡稱biofor ）工藝具有體積小、容積負荷高、水力負荷大、水力停留時間短、所需基建投資少、處理出水水質好等特點，國外已廣泛應用，國內也在多個行業的水處理中成功應用。

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

試驗表明:對有機物的去除主要發生在進水端60cm內，對氨氮的去除主要發生在進水端120cm內;曝氣生物濾池運行的最佳氣水比為3 : 1 4 : 1 ;在進水有機物和氨氮濃度比較小時，水力負荷對其去除率影響不大;在氣水比為3 : 1 ，進水氨氮負荷小於0 . 87kgnh4 + - n / m3 （濾料） ? d時，出水氨氮小於5mg / l ，滿足回用水的要求;在不同有機負荷下，有機物去除率保持在35 % 45 % 。

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。
