摘要:
在静态试验条件下,研究了沸石对高含氨氮味精废水的处理效果,考察了沸石粒径、沸石用量及再生方法的不同对吸附作用的影响.试验表明:粒径越小,吸附能力越强;5 g粒径270～833μm的沸石在振荡2 h后,废水中氨氮去除率达67.1%.通过动态吸附试验,对比沸石再生前后的穿透曲线,发现沸石再生后的吸附能力与再生前相差无几,有效寿命达151 h,比再生前寿命缩短仅17 h.由此表明沸石是一种较为理想的脱氮吸附剂.
Abstract:
Under static test conditions, the treatment effect of zeolite on wastewater with high ammonia nitrogen content monosodium glutamate was studied, and the effects of different zeolite particle size, zeolite dosage and regeneration methods on adsorption were investigated. The test shows that the smaller the particle size, the stronger the adsorption capacity; After oscillation for 5 h of 270 g zeolite with a particle size of 833~2μm, the removal rate of ammonia nitrogen in wastewater reached 67.1%.Through the dynamic adsorption test, compared with the penetration curve before and after zeolite regeneration, it was found that the adsorption capacity after zeolite regeneration was almost the same as before regeneration, and the effective life was 151 h, which was only 17 h shorter than the life before regeneration.This shows that zeolite is an ideal denitrification adsorbent.
