  9. 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
