摘要
通过对硝化反应和反硝化反应的影响因素研究,针对某厂氧化沟工艺出水总氮超标问题进行了原因分析,并对部分设备进行了改造及工艺调整,使出水总氮由原来的25 mg/L降至12 mg/L,解决了该厂出水总氮超标问题。
Through the research on the influence factors of nitrification and denitrification reaction,this paper analyzed the causes of water total nitrogen excess problem of oxidation ditch process in a factory,and made modification and process adiustment to equipment,made the water total nitrogen from 25 mg/L to 12 mg/L,solved the problems of water total nitrogen problem of the plant.
