曝气式微电解技术处理含氨氮废水

Treatment of Ammonia Wastewater by Aeration Fe-C Micro-electrolysis Process

通过对化工行业含氨氮废水的进行微电解试验研究,优化试验参数,采用曝气式微电解处理技术对于该类废水的进行实验性研究,并获得最佳试验参数:铁炭比1︰1,pH值4.0,反应时间40 min,气水比15︰1。氨氮的去除率达到55%左右,研究表明,在微电解强氧化的环境中,可以将氨氮进行氧化去除。

Through the micro-electrolysis experimental study on the chemical industry waste water containing ammonia nitrogen,test parameters were optimized.The aeration micro electrolysis process was used to treat this kind of wastewater,and the optimum parameters were obtained as follows： the ratio of iron to carbon 1︰1,pH 4.0,reaction time 30 min,ratio of gas and water 15︰1.Under above conditions,the ammonia removal rate can reach about 75%.The research result shows that,in the micro electrolysis oxidation environment,ammonia can be removed by oxidation.
