| 摘 要： | 直接向城市污水初沉池出水中投加沸石 ,利用沸石对氨氮的选择性交换去除其中的氨氮 ,并辅以实验室配制液作为对比。研究结果表明 :( 1)沸石对初沉池出水中的氨氮具有很强的选择性 ;( 2 )与实验室配制液相比 ,在城市污水初沉池出水中沸石的交换容量受其他离子和有机物的影响而有所下降 ,但下降并不明显 ;( 3 )沸石对初沉池出水中的COD也有一定的去除效果

| Abstract: | Zeolite was directly put into the effluent of the primary sedimentation tank of municipal wastewater plant, using the function of selective ion exchange of the zeolite to remove partly the ammonia-nitrogen. The removal efficiency of the artificial solution is also studied. The results are as follows: (1) Zeolite has a great selective exchange ability to removal ammonia-nitrogen in the effluent of the primary sedimentation tank. (2) Comparing with the artificial solution, the zeolite's capacity of ion exchange to the sewage is slightly lower because of the influence of other ions and the organic substances, but it's not very obvious. (3) The zeolite has some help for the COD removal. |
