【摘要】：采用人造沸石對模擬氨氮廢水進(jìn)行吸附,并對其進(jìn)行電化學(xué)再生,探討了吸附及再生的影響因素。結(jié)果表明,最佳吸附條件:吸附時(shí)間為90 min,pH為中性或弱酸性,人造沸石投加量為120 g/L,在此條件下,氨氮去除率可達(dá)84%;最佳再生條件:電解時(shí)間為40 min,Na Cl濃度為0.1 mol/L,溫度為50℃,pH為10,在此條件下,人造沸石再生率可達(dá)到97.48%。人造沸石重復(fù)使用6次后,再生率仍可達(dá)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，
