“曝气生物活化滤池-人工快滤”组合工艺处理锰工业聚集区受污水体试验研究

An experimental study of the combined process of “biological aerated filter-artificial rapid infiltration system” applied in the treatment of polluted water body in manganese industrial cluster

通过利用"曝气生物活化滤池-人工快滤"组合工艺,对广西"锰三角"地带锰工业聚集区受锰和氨氮污染水体的处理效果进行研究,发现该组合工艺可同时去除受污水体中的锰和氨氮,去除率均可达到60%以上,而且该工艺成功解决了沸石填料更换困难、人工快滤占地面积大的瓶颈问题,反应装置简单易于管理、运行成本较低。

By applying the combined process of＂biological aerated filter-artificial rapid infiltration＂,the authors conducted research on its treatment effect on the water body polluted by manganese and ammonia nitrogen in manganese industrial cluster of Guangxi＂manganese triangle＂area.The results indicated that this combined process was able to remove both the manganese and ammonia nitrogen in the polluted water body while the removal rate could be 60%and above.This process successfully solved the bottleneck problems like replacement difficulties of zeolite filler and oversized artificial rapid infiltration system,and the reaction unit could be easily managed with relatively low running cost.
