2) water COD measurement
水质COD测量
3) COD substances
COD物质
4) influent COD
进水COD
1.
The result shows that when influent COD is about 150 mg/L and 200 mg/L, denitrification rate is increased with the increase of C/N ratio; while COD is about 100 mg/L, the denitrification rate is decreased with the increased time.
进水COD浓度及C/N值是影响系统反硝化效果的两个重要参数,为此研究了不同进水COD浓度在不同C/N值条件下的脱氮效果。
6) effluent COD
废水COD
1.
Peroxide bleaching of mechanical pulp requires alkaline conditions,which cause an increase of the effluent COD.
机械浆H2O2漂白要求在碱性条件下进行,会引起废水COD增高。
