摘要
对目前几种实际可行的氨氮废水处理技术进行了综述和分析对比,着重讨论了各处理技术的应用条件、氨氮处理效果及处理成本。旨在通过对各技术的处理效果及成本分析,为氨氮废水处理的研究与应用提供快捷的参考,以使在实际应用中针对不同类型废水能迅速找出最为经济合理且高效的氨氮处理方法及组合。通过分析对比,得出生物法和氨吹脱处理氨氮废水费用最低,分别为2～20元/(kgNH4+-N)和1.8～10元/(kgNH4+-N);磷酸铵镁沉淀单位处理费用最高,为50～70元/(kgNH4+-N);折点氯化单位处理费用介于上述之间,在37.6元/(kgNH4+-N)左右。
Several feasible techniques for the treatment of ammonium nitrogen wastewater are reviewed and compared, their application conditions, ammonium nitrogen removal efficiency and treatment costs are discussed. Through analyzing the removal efficiencies and costs of various techniques, this review is aiming to provide a shortcut reference for the research and application of ammonium nitrogen wastewater treatment, which may give helps in rapidly finding a most economical, reasonable and cost-effective method or combination in practical application in different type of wastewater treatment. Through analysis and comparison, it was found that techniques of biological treatment and ammonia stripping for treating ammonium nitrogen wastewater have the lowest costs, which are 2--20 and 1.8-- 10 yuan/kg NH4^＋-N, respectively; the technique of MAP precipitation has the highest cost, which is around 50--70 yuan/kg NH4^＋-N; and the cost of breakpoint chloride method is about 37.6 yuan/kg NH4^＋-N, which is in between the above.
