Experimental results show that the water velocity is that when the BV ammonia concentration of 50 mg, L - 1 simulation wastewater and 98 mg, L - 1 point of industrial wastewater, penetrate respectively C/C0 = 0.3 and 0.15, water column of natural zeolite could handle respectively; 126 BV, 43 BV Modified zeolite column can handle respectively 157 BV, water, and with 46 BV hydraulic load increases, zeolite column can reduce water treatment, The experiment was found to leak after 8 NaCl solution with zeolite desorption regeneration effect is good, low cost, regeneration of zeolite adsorption capacity decrescent, Test through dynamics analysis found that zeolite column of ammonia nitrogen adsorption fast.

实验结果表明，进水速度为2.72 BV时，通入氨氮浓度为50 mg·L-1的模拟废水和98 mg·L-1的工业废水，此时穿透点分别为C/C0=0.3和0.15时，得到天然沸石柱可处理水量分别为126 BV、43 BV；改性后沸石柱可处理水量分别为157 BV、46 BV，且随水力负荷增大，沸石柱可处理水量减小；试验还发现对泄露后沸石用8%NaCl溶液解吸再生效果好，成本低，再生后的沸石吸附容量变小；试验通过动力学分析发现沸石柱吸附氨氮速度较快。

It contains much turmeric ramification, which is dyeable and difficult dedradable surfactant, and its biodegradability is not good.
