低温环境下内置腐殖土填料SBR系统处理糠醛废水

Treatment of furfural wastewater using SBR system with built-in humus soil media at low temperatures

在水温为5～10℃左右的条件下,通过实验对比了传统SBR系统与内置腐殖土填料式SBR系统处理糠醛废水的效能,结果表明:由于内置腐殖土填料的作用,填料式SBR系统的去除效能要高于未装填料的SBR系统;传统SBR系统的COD、氨氮和总氮的去除率分别为89%、85%和59%,出水浊度为8.6 NTU;填料式SBR系统的COD、氨氮和总氮的去除率分别为95%、90%和71%,出水浊度为1.7 NTU。

Effects of traditional SBR system and SBR system with built-in humic soil treating furfural wastewater were researched at low temperatures（5~10 ℃）.The results show that the removal effects of COD,NH＋4-N,TN and turbidity of the SBR system with humus soil were better.The removal rates of COD,NH＋4-N and TN of traditional SBR system were 89%,85% and 59%,respectively,the turbidity was 8.6 NTU.On contract,the removal rates of COD,NH＋4-N and TN of the SBR system with humic soil built-in were 95%,90% and 71%,respectively,and the turbidity was 1.7 NTU.
