摘要
采用硝化与反硝化工艺进行焦化废水生物脱氮试验,结果表明:在控制一定的工艺参数条件下,可以将500mg·L-1左右的ρ(NH3-N)降至15mg·L-1以下,COD的去除率达85%。
This article introduced trial reseach of adopting nitration and anti- nitration technique treating coking polluted water to biologically remove nitrogen, results of reseach indicated that in contral of special technical parameter, the thickness of NH3-N was put down from 500 mg·L^-1 to 15 mg·L^-1, disposal efficiency of COD reaches 85%.
