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NH4+-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NH4+-N作用影响很大.水温越高,生物修复工艺除NH4+-N效果越好.在较低水环境温度下,水温变化对生物修复工艺除NH4+-N作用效果影响最大;在日常水体温度下,水温变化对生物修复工艺除NH4+-N作用效果影响最小;在水体温度较高的条件下,水温变化对生物修复工艺除NH4+-N作用效果影响较小.Abstract: The effect of NH4+-N removal in a polluted raw water of water sources by the bioremediation process with the elastic fillings and micropore aerators was studied in this paper.The effect of waterbody temperature on the NH4+-N removal in the polluted water sources was also discussed. The results show that the waterbody temperature is an important factor effecting the bioremediation process. The temperature has the biggest effect on the removal of NH4+-N for the bioremediation process under low waterbody temperature. The temperature has a smaller effect on the removal of NH4+-N for the bioremediation process under higher waterbody temperature.
