摘　　要：对PCB废水总氮的处理,从源头削减、分质收集、分质预处理到末端处理提出了多种方法,着重分析了MAP+管式微滤膜处理氨氮废水、多级组合式RO处理硝态氮废水和A2O+MBR处理综合废水,提出PCB废水总氮达标的组合工艺,项目建成后达到预期效果。Minifying from source, collection and pre-treatments with different quantities, and terminal treatment are provided for the treatment for total-nitrogen in wastewater from PCB. Treatments for ammonianitrogen wastewater with MAP + tubular micro-filtration membrane, for nitrate-nitrogen wastewater with multistage RO, and for comprehensive wastewater with A2O+MBR are emphatically analyzed respectively. Combined process is provided for total-nitrogen removal, excepted effect is achieved in treatment project.
