鐵屑去除酸法地浸采鈾地下水中硝酸鹽的試驗研究( 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 ）生物濾池對亞硝酸鹽氮的去除效果比較好，試驗期間，水源水中亞硝酸鹽氮濃度范圍為0 . 01 2 . 23mg / l ，出水濃度一般低於0 . 10mg / l ，水溫、濾速、氣水比對亞硝酸鹽氮的去除無明顯影響。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。Removing impurity, nitrate, metal ion, soluble inorganic, organic compound, trihalogenmethane, pesticides, dioxin, color and odor
