| 摘 要： | 定期监测两种不同形态的溢流堰坝体上下点的溶解氧及水质变化,研究溢流堰形态对水体营养盐及有机污染的影响。结果表明:两种不同形态的溢流堰均可较好地提高水体的DO含量,且阶梯式溢流堰较斜面式溢流作用明显;高锰酸盐指数IMn、NH3-N、TP含量均减少,平均去除率阶梯式溢流堰均优于斜面式溢流堰。

| Abstract: | The influence of overflow dam shape on nutrient and organic contaminants is studied by monitoring the DO and the change of water quality timely.It indicates that the dissolved oxygen of the water body all increases by the two dams with different shapes dams,the function of the stepped overflow dam is more obvious than the bevel surface overflow dam,and the content of I_(Mn),NH_3-N and TP is decreased,the average removal rate in the influent of the stepped overflow dam is better than the bevel surface overflow dam. |

| Keywords: | overflow dam DO I_(Mn) NH_3-N TP and self-purification |
