摘要:

针对某黄金矿山尾矿库淋溶液中氨氮的去除开展试验研究,考察离子交换法、化学沉淀法、折点氯化法及新型药剂法处理效果。结果表明:离子交换法和化学沉淀法对氨氮的处理效果不佳;折点氯化法及新型氨氮去除剂对尾矿库淋溶液中各污染物均具有较好的处理效果,且2种方法药剂处理成本相差无几,但考虑到使用过程安全性及二次污染,确定新型药剂法为最佳处理方法,其最佳处理条件为1号、2号新型氨氮去除剂投加量为3 g/L,反应时间为30 min。

Abstract:

Experimental research was carried out on the removal of ammonia nitrogen from the leaching solution of tailings reservoir in a gold mine and examined the treatment effect of ion exchange, chemical precipitation, breakpoint chlorination and new type reagent methods.The results show that the ion exchange and chemical precipitation methods don’t have good ammonia nitrogen treatment effect; the breakpoint chlorination and new type ammonia nitrogen removal reagent have good treatment performance on each pollutant in the leaching solution of tailings reservoir, and the two methods have nearly the same cost.However, considering the safety and secondary pollution, the new type reagent method is decided to be the optimal treatment method and the optimal conditions are: the dosage of No.1 and No.2 new type ammonia nitrogen removal reagent is 3 g/L and the reaction time is 30 min.
