摘要
一定温度条件下,采用空气吹脱和物理吸附两步处理高浓度的氨氮废水,研究了影响其效率的主要因数,并对相关参数进行了优化。结果表明,在废水温度高于50℃,pH不低于11的情况下,直接空气吹脱可以除掉93%的氨氮,进一步用活性炭吸附后即可达标排放。
At a certain temperature,two steps of air stripping and physical adsorption were used to treat high concentration ammonia nitrogen wastewater.The main factors affecting the efficiency were studied,and the relevant parameters were optimized.The results showed that 93%of ammonia nitrogen can be removed by direct air stripping when the temperature of wastewater was higher than 50℃and pH was not lower than 11.After further adsorption with activated carbon,it can meet the discharge standard.
