吸附剂用量对二级出水中氨氮去除效果的研究

以二级出水中氨氮的吸附处理为研究对象，对活性炭吸附法和沸石吸附法去除二级出水中氨氮进行试验研究。在一定范围内，吸附剂用量对氨氮的去除效果有较大的影响，相同条件下，吸附剂投加量越大，氨氮去除率越高，但增加到一定程度后，对氨氮的吸附作用减弱，在实际应用中控制吸附剂的投加量是必要的。当吸附剂用量为15 mg时，活性炭吸附效果要明显高于沸石的；当吸附剂用量大于30 mg时，沸石的吸附效果要远远好于活性炭的。

Removal Effect of Adsorbent Dosage on Secondary Effluent of Ammonia Nitrogen

Taking secondary effluent ammonia nitrogen adsorption as the research object , this study conducted an experiment about on ammonia nitrogen adoption by using activated carbon and zeolite .Within a certain range, adsorbent dosage has a great impact on the removal efficiency of ammonia nitrogen.Under the same conditions, the larger the adsorbent additive amount, the higher the removal rate of ammonia nitrogen.But when the dosage reached a certain degree, the adsorption effect on ammonia ni-trogen decreases.When the adsorbent dosage is 15 mg, the adsorption effect of activated carbon is significantly higher than that of zeolite; when the adsorbent dose is greater than 30 mg, zeolite adsorption effect is far better than that of activated carbon.
