碳素纤维生态草对兰州新区人工水体的水质改善试验研究

摘要

Carbon fiber (CF)was used as biofilm carrier to treat polluted lake in Lanzhou new area.The effect of CF on removal of pollutants was investigated.The results showed that CF has a good effect on the pollution of artificial lake in lanzhou new area. The removal rate increases as the area of CF is increased and the removal effect of 6 gCF is more stable.,COD,TP,NH3-N,TN and turbidity declined by 61.53%,60.86%,89.62%,29.71% and 92.57% after treating for 28 days.It indicated that the carbon fiber is a feasible technique for the polluted lake in Lanzhou new area.%以碳素纤维(CF)生态草为载体,处理兰州新区人工湖受污染湖水,考察CF生态草对湖水污染物的去除效果.结果表明,碳素纤维生态草对兰州新区人工湖污染物有较好的去除效果,且去除率随着投放CF的面积的增大而增大,投放6 g CF的去除效果更稳定,经过28 d处理后,ρ(COD), ρ(TP), ρ(NH3-N),ρ(TN)和浊度分别下降61.53%, 60.86%,89.62%,29.71%和92.57%.,这表明利用CF生态草对兰州新区人工湖受污染湖水的治理是可行的.
