| 摘 要： | 通过小试试验,研究了以玉米芯为反硝化碳源和生物膜载体的生物反应器在启动阶段对污水中COD及硝酸盐的去除效果。结果表明,在模拟废水COD100 mg/L、NO3--N40 mg/L,pH值6.5～7.5条件下,13 d挂膜后间歇处理后的废水COD可降至30 mg/L,18 d挂膜后废水NO3--N降至2 mg/L以下。

| Abstract: | The removal effect of biological reactor with corncob as carbon source and bioflim carrier for denitrification on COD and nitrate in sewage in starting stage was studied through bench-scale test.The results indicated that under the condition of simulated sewage containing 100 mg/L COD and 40 mg/L NO-3-N and with pH value of 6.5-7.5,after 13 days′ bioflim formation,the COD content in sewage could be reduced to 30 mg/L and after 18 days′bioflim formation,the NO-3-N content in sewage could be reduced to lower than 2 mg/L. |
