Impacts of Carbon Fiber on Eutrophic Water Quality Improvement and Its Algal Community Structure

  • 摘要: 以北京朝阳区清河水为原水,开展碳素纤维生物修复试验,考察生物膜从形成到成熟及处理过程中碳素纤维外观、生物相结构、氮磷浓度及藻类群落结构的变化. 结果表明,碳素纤维在3 d内挂膜成功且生物相丰富,说明其生物亲和性强,吸附性能好. 碳素纤维生物膜对氮、磷具有较好的去除效果,TN、TP、NH4+-N去除率分别达40%、60%、98%,其中对氮、磷的去除以吸附水体中颗粒态污染物为主. 碳素纤维生物膜对富营养化水体藻类的增殖有明显的抑制作用,尤其对蓝藻的抑制作用显著,藻类总密度和蓝藻密度达到最大值的时间与对照组相比延迟6 d,且藻类总密度及蓝藻密度都低于对照组. 碳素纤维生物膜还影响水体中的藻类群落结构,试验期间水体中以硅藻为主,蓝藻所占比例平均为22.4%,而对照组中以蓝绿藻占优,蓝藻平均所占比例高达47.2%.
