摘　　要：河道污染日益加剧,急需探索出一种经济有效的河道水质改善方法。通过室内动态试验研究,考察底泥及不同水力条件下联合投加生物促生剂对河道水质净化效果的影响,初步探索出水质改善效果的变化规律。研究表明,在有底泥条件下联合投加生物促生剂,其水体的水质改善效果较好,经修复后的水体DO提高,浊度降低,并得出0m/s为N,P降低的最佳流速。At present, fiver pollution picks up increasingly and it＇s necessary to explore an economical and effective method to improve the water quality. The indoor test under simulated dynamics of water body studied the effect of sediments and different hydraulic conditions by injecting bio-energizer （BE） to improve the fiver water quality and found the change rule of water quality improvement effect .The study indicated that sediment and BE played a significant role in water purification, the water bodies improved DO and reduced turbidity after restoration, and 0 m/s was the best velocity of nitrogen and phosphorus removal.
