工业废水中氨氮处理方法比较分析

Comparative analysis on the treatment of ammonia nitrogen in industrial wastewater

氨氮已作为我国"十二五"水污染控制约束性指标。针对含氨氮废水进行处理,并实现达标排放是当前研究的热点。基于已有的实际工业废水处理应用案例,对比分析了吹脱法、吸附法、化学沉淀法、折点氯化法、生物脱氮法等处理工业氨氮废水的适用条件(进水氨氮浓度、处理时间、温度、pH等)和处理效果,并总结了不同处理方法的工艺特点及其优缺点,可以为氨氮废水处理工艺和参数选择提供参考。

Ammonia nitrogen has been a water pollution control binding target in the 12th Five-Year Plan. Treating the wastewater containing ammonia nitrogen and reaching the goal of discharge standards have been the hot spot of current study. Based on the industrial wastewater treatment application cases of actual industrial wastewater treatment technologies, blow-off method, adsorption method and biological nitrogen removal method, as method, chemical precipitation method, breakpoint chlorination well as appropriate conditions of ammonia nitrogen wastewater treatment, such as influent ammonia nitrogen concentration, treatment time, temperature, pH, etc., are compared and analyzed. At the same time ,the technological characteristics of different treatment methods and their advantages and disadvantages are summarized, providing reference for the ammonia nitrogen wastewater treatment technologies and parameter selection.
