摘要:
采取改进型人工快速渗滤系统对南方离子型稀土开采过程中产生的氨氮废水进行处理,工程稳定运行29个月。数据表明,经过两级人工快渗处理后,氨氮去除率达到97%以上,出水氨氮浓度稳定在5 mg/L以下;平均总氮去除率为39.34%;COD出水在30mg/L以下,处理效果优良。对工程中的填料进行高通量分析结果表明,人工快速渗滤系统对总氮的去除,是厌氧反硝化和好氧反硝化共存的脱氮机理。
Abstract:
An improved artificial rapid infiltration system was adopted to treat the ammonia nitrogen wastewater produced in the process of ionic rare earth mining in southern China. The project has operated stably for 29 months. The data show that after two-stage artificial rapid infiltration treatment, the ammonia nitrogen removal rate is more than 97%, and the ammonia nitrogen concentration in the effluent is stable below 5 mg/L the average total nitrogen removal rate is 39.34% COD effluent is less than 30mg/L, and the treatment effect is excellent. The high flux analysis of the fillers in the project shows that the removal of total nitrogen by the artificial rapid infiltration system is a nitrogen removal mechanism of the coexistence of anaerobic denitrification and aerobic denitrification.
