废水中硝态氮来源、转化及去除方法

The source,transformation and removal method of nitrate nitrogen in wastewater

总结了工业废水中硝态氮的天然来源和人为来源,探讨了硝态氮在自然过程中和水处理过程中的转化途径,最后对近些年来工业废水中硝态氮的处理技术,包括化学脱氮、物理脱氮和生物脱氮法进行了综述.

The natural and anthropogenic sources of nitrogen in the form of nitrate （NO3- --N） in industrial wastewater were summarized. The transformation pathways of NO3- --N were also discussed in the process of environmental cleanup and wastewater treatment. At last, the processing technology for the removal of NO3 -- N in recent years including physical treatment, chemical treatment and biological treatment were introduced.
