为定量研究河道滚水坝对水体溶解氧和高锰酸盐指数的影响，选择一城市河道小型滚水坝，在坝前和坝下设监测点，定期监测水质变化。
In order to study the influence of urban river overflow dam on dissolved oxygen and COD_ ( Mn ), a small overflow dam in an urban river was selected and two sample points were fixed to monitor the changes of water quality timely .

水中部分污染物的降解使水体的CODMn负荷减轻，滚水坝对CODMn的平均去除率为3.81%。
The load of COD_ ( Mn ) is reduced and a part of contaminants in the water body is degraded after the overflow dam , the average removal rate of COD_ ( Mn ) is 3.81 % .
