【摘要】:采用人造沸石对模拟氨氮废水进行吸附,并对其进行电化学再生,探讨了吸附及再生的影响因素。结果表明,最佳吸附条件:吸附时间为90 min,pH为中性或弱酸性,人造沸石投加量为120 g/L,在此条件下,氨氮去除率可达84%;最佳再生条件:电解时间为40 min,Na Cl浓度为0.1 mol/L,温度为50℃,pH为10,在此条件下,人造沸石再生率可达到97.48%。人造沸石重复使用6次后,再生率仍可达到88%以上。
[Abstract]:The simulated ammonia nitrogen wastewater was adsorbed by artificial zeolite and electrochemical regeneration was carried out. The influencing factors of adsorption and regeneration were discussed. The results show that the optimum adsorption conditions are as follows: the adsorption time is 90 min, pH is neutral or weak acid, the dosage of artificial zeolite is 120 g / L, under this condition, The optimum regeneration conditions are as follows: the electrolysis time is 40 min, the concentration of NaCl is 0.1 mol / L, the temperature is 50 鈩,
