离子型稀土矿氨氮污水微藻光合脱氮的研究进展

Research Progress on Treatment of Rare Earth Ammonia Nitrogen Wastewater by Microalgae

离子型稀土矿以硫酸铵为浸矿剂采用原地浸矿工艺进行开采,会产生大量氨氮污水。利用微藻去除高浓度的氨氮是近年稀土氨氮污水处理研究的热点,本文讨论了影响微藻脱氮能力的因素,并提出了实际应用于稀土氨氮污水的解决方法,以期更高效、更经济环保地处理稀土氨氮污水。

Ionic rare earth ore is mined by in-situ leaching process with ammonium sulfate as leaching agent,which will produce a large amount of ammonia nitrogen sewage.In recent years,the utilization of microalgae to remove high concentration of ammonia nitrogen in rare earth ammonia nitrogen wastewater treatment is a hot spot.This paper discusses the factors affecting the ability of microalgae to remove nitrogen and puts forward practical solutions for rare earth ammonia nitrogen wastewater treatment,in order to treat rare earth ammonia nitrogen wastewater more efficiently,economically and environmentally friendly.
