摘要: 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。Abstract: 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.
