摘要
针对黑臭河道特性,开展生态修复技术实验研究。根据污染物去除效率及工艺组合,将实验区分为预处理调节区、强化净化区、自然修复区,运行监测结果显示,各项污染指标去除效果良好。对轻度黑臭水体,COD、NH3-N、TN和TP去除效果分别达到36.40%、53.65%、46.83%和61.64%。对重度黑臭水体,COD、NH3-N、TN和TP去除效果分别达到67.11%、49.43%、47.36%和45.62%。并在自然修复区开展了5种水生植物培育试验,优选出的蜘蛛兰、风车草具备较好的耐盐、耐淹、耐污和水质净化能力,得以正常快速生长。
According to the characteristics of the black smelly river,experimental research on ecological restoration technology was carried out.Based on the pollutants removal efficiency and technology combination,the experimental area was divided into preprocessing adjusting area,strengthening the purification area,natural repair area according to the operation monitoring of the results.The removal effect of various pollution indicators was good for the light black smelly water,the removal efficiency of COD,NH 3-N,TN and TP were 36.40%,53.65%,53.65%and 36.40%,respectively,for the heavy black smelly water.The removal efficiency of COD,NH 3-N,TN and TP were 67.11%,49.43%,47.36%and 45.62%.Natural repair area has been carried out in five kinds of aquatic plant breeding experiment,optimizing the spider,windmill grass has good resistance to salt,submergence tolerance,dirt and water quality purification capacity,fast growth to normal.The research results will provide some technical support for the ecological restoration of black smelly rivers.
