摘要:

在焦化厂废水处理站增加反硝化生物脱氮装置,能进一步降低焦化废水处理系统出水的总氮含量,反硝化系统的总氮去除效率可达88.04%,焦化废水处理系统出水总氮含量达到了15.78 mg/L,低于《炼焦化学工业污染物排放标准》中总氮20 mg/L的限值。

关键词: 焦化废水; 生物脱氮; 反硝化 ,

Abstract:

This paper introduces an additional biological denitrification unit to the coking wastewater treatment station, which can further reduce the total nitrogen content in the effluent of the coking wastewater treatment system.The total nitrogen removal efficiency can reach 88.04%.The total nitrogen content in the effluent of the coking wastewater treatment system can reach 15.78 mg/L,which is less than the limit of 20 mg/L in the Emission Standards of Pollutants for Coking Chemical Industry.

Key words: Coking wastewater, Biological denitrification, Denitrification
