真空脱氮法治理高浓度氨氮废水技术初探

Preliminary Study on Denitrogenation of High Concentration Ammonia Nitrogen Wastewater by Vacuum Treatment

随着工业的发展,高浓度氨氮废水对环境的影响越来越严重,而目前针对高浓度氨氮废水的治理方法中均存在一些缺陷,难以圆满解决高浓度氨氮废水的治理难题。受供暖及制冷水脱气技术的启发,结合现有脱氮技术的研究,可采用真空脱氮法对高浓度氨氮废水进行治理,现已取得实验室测试的成功,表明采用真空脱氮法可以有效治理高浓度氨氮废水,并可以减少运行费用、二次污染,实现废物综合利用。

With the industrial development,high concentration of ammonia nitrogen wastewater has made increasingly serious impact on the environment,and at present,some flaws in the treatment process are to be solved urgently.Inspired by the heating and cold water-degassing technology,combined with the existing nitrogen removal techniques,the vacuum method can be used to treat high concentration ammonia nitrogen wastewater.Laboratory testing has already been made successfully,which indicated that denitrification method by vacuum treatment can effectively control high concentration of ammonia water,and can reduce operating costs,secondary pollution and achieve comprehensive utilization of wastes.
