摘要
氧化塘中加入了植物,由于植物的光合作用,水中的溶解氧增加,对污水的处理效率有明显提高.本文考查了溶解氧随日照、季节及进水浓度的变化而变化的情况,并比较了有、无植物塘对污水的处理效果,发现有植物氧化塘对污水中的COD去除效率高20%～30%.
For the photosynthesis of plant in pond, its DO concentration and removal efficiency are increased. The influences of sunlight, season and influent concentration are investigated. And the removal efficiency between aquatic-plant pond and unplanted-pond are compared. The results show that its removal efficiency of wastewater in planted 20% pond is percent higher than that in unplanted-pond.
