[摘要] 針對河湖水環境治理工程中的原位曝氣問題,以岳陽王家河底泥為研究對象,在不同曝氣方式?位置下完 成靜置釋放?連續曝氣?間歇曝氣及泥水界面曝氣底部曝氣,對底泥中污染物的釋放規律和影響作用進行系統研 究。 研究表明曝氣措施在河湖水環境治理工程中,能有效提升河湖環境,同時底部間歇式曝氣比連續曝氣?界面曝 氣在運行能耗等方面更具優勢,為王家河水環境治理設計方案的選擇提供依據。

Abstract:Aiming at the in-situ aeration problem in river and lake water environment treatment project, taking the sediment of Wangjiahe river in Yueyang as the research object, the simulation is used in laboratory, static release, continuous aeration, intermittent aeration, mud-water interfacial aeration and bottom aeration is completed under different aeration modes and positions, the regularity and influence of pollutant release in sediment are studied systematically. The research shows that aeration can effectively improve the river and lake environment. At the same time, intermittent bottom aeration is more advantageous than continuous aeration and interfacial aeration, in terms of energy consumption, a basis for the selection of water environment control design scheme of Wangjiahe river is provided.
