滴滤塔填料对比试验研究

Study on Comparison Test of Trickuny Filter

[目的]提高滴滤塔污染物的去除效率。[方法]考察了沸石、陶环2种新型填料对COD、NH4-N、TN、TP的去除效果。[结果]沸石填料运行稳定,具有更好的污染物去除效果。[结论]采用天然沸石作为填料的滴滤塔具有处理成存低、运行稳定、氨氮去除效率高等特点,在村镇污水处理领域县有较高的推广价值。

[Objective] The aim was to improve removal efficiency of trickling filte pollutant.[Method] Removal efficiency of eolite and figuline ring in two new packing on COD,NH4-N,TN,TP were investigated.[Result]The study showed that zeolite packing operation was stable zeolite filler had better pollutant removal effect and operation stability.[Corclusion]Trickling filter with zeolite as filler had low cost,Stable operation,high removal efficiency of NH4-N,and had popularization value in wasterwater treatment field in villages.
