为了研究沸石吸附氨氮的动态规律及再生性质，试验用沸石作为填料柱建立模拟装置，通过对装置通入模拟氨氮废水和工业废水试验，得出沸石柱吸附氨氮的穿透曲线和水力负荷曲线，并对吸附饱和后的沸石柱进行化学解吸再生试验，对整个装置运行过程进行动力学分析研究。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。采用沸石吸附氨氮具有效果好，反应快，可再生的优点，是处理氨氮废水的优良吸附材料。 [ Last edited by qingfeng877680 on 2009-12-7 at 20:31 ] |

| In order to study the dynamics of ammonia nitrogen adsorption of zeolite and regeneration properties, used as filler column establish simulation zeolite molecular devices, through the simulation of ammonia nitrogen wastewater and industrial wastewater test, zeolite column of ammonia nitrogen adsorption penetration curve and hydraulic load curve, and the absorption of zeolite column after saturated chemical experiment of the regeneration, desorption unit operation process of dynamic analysis research. 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. Using zeolite adsorption of ammonia nitrogen has good effect, fast response and renewable, treatment of ammonia nitrogen wastewater is excellent adsorption materials. |

| In order to study the zeolite adsorption ammonia nitrogen the dynamic rule and the regeneration nature, experiments takes the filled column establishment analog calculator with the zeolite, through passes over the simulation ammonia nitrogen waste water and the industrial waste experiment to the installment, obtains boils the stone column adsorption ammonia nitrogen the penetration curve and the water power load diagram, and after adsorbing saturated to boil the stone column to carry on chemistry desorption regeneration experiment, conducts dynamics analytical study to the entire installment movement process. The experimental result indicated that when enters the water speed is 2.72 BV, passes over the ammonia nitrogen density is 50 mg•L-1 simulation waste water and 98 mg•When the L-1 industrial waste, this time penetrates respectively is C/C0=0.3 and 0.15, obtains boils the stone column to be possible naturally to process the water volume respectively is 126 BV, 43 BV; After the modification, boils the stone column to be possible to process the water volume respectively is 157 BV, 46 BV, and increases along with the water power load, boils the stone column to be possible to process the water volume to reduce; The experiment also discovers after revealing the zeolite is good with the 8%NaCl solution desorption regeneration effect, the cost is low, after the regeneration zeolite loading capacity changes is small; The experiment boils the stone column adsorption ammonia nitrogen speed through dynamics analysis discovery to be quick. Uses the zeolite adsorption ammonia nitrogen to have the effect to be good, responds quickly, the renewable merit, is processes the ammonia nitrogen waste water the fine adsorption material. |
