天然水体环境温度对生物修复工艺除NH+4-N效果影响分析

Analyse Effect of Waterbody Temperature on Removal of NH+4-N in Polluted Water Sources by Bioremediation Process

    摘要
  • 摘要: 采用弹性填料微孔曝气生物修复方法净化受污染的某饮用水源,探讨了天然水体环境温度变化对生物除NH+4-N作用效果的影响.结果表明,水体环境温度对生物修复工艺除NH+4-N作用影响很大,水温越高,生物修复工艺除NH+4-N效果越好,在较低的水体环境温度下,水温变化对生物修复工艺除NH+4-N作用效果影响最大;在日常水体环境温度下,水温变化对生物修复工艺除NH+4-N作用效果影响最小;在水体环境温度较高条件下,水温变化对生物修复工艺除NH+4-N作用效果影响较小.

     

    Abstract: The effects of NH+4-N removal in a polluted drinking water source by the bioremediation process with the elastic fillings and micropore aerators has been studied.The effect of waterbody temperature on the NH+4-N removal has also been discussed.The results show that the waterbody temperature is an important factor affecting the bioremediation process.The higher the temperature is,the better the results of NH+4-N removal for the bioremediation process is obtained.The temperature has the biggest effect on the removal of NH+4-N for the bioremediation process under low waterbody temperature,while it has the smallest effect under ordinary waterbody temperature.The temperature has a smaller effect on the removal of NH+4-N for the bioremediation process under higher waterbody temperature.
