污染河道的生态修复机理研究

Study on Polluted Riverway Ecosystem Rehabilitation Mechanism

随着经济的发展 ,含有机物质的生活污水和工业废水排入河道导致河水含氧量下降 ,河道水生态系统变得十分脆弱 .应用生态工程学理论 ,探讨河道生态修复机理 。

With the development of the economy, the domestic wastewater and the industrial sewage which contain a lot of organic component were drained into riverway result in the oxygen content of the water declining. The riverway ecosystem was become terribly frangibility. It was discussed riverway polluted ecosystem rehabilitation mechanism based on ecological engineering science theories, and indicated satisfying riverway ecological required water was key to come back river ecosystem for short of water.
