一体化装配式深水曝气平台系统及其在湖泊水库生态修复工程中的应用

Integrated assembled deep water aerator(TIBEAN)and its applications in lake and reservoir management and remediation

针对具有热力学分层特征的受污染湖库的深水曝气技术在欧洲已有超过25年的研发、设计和建造运营经验,其技术的实现载体为一体化装配式深水曝气平台系统,该系统适用于大型分层水体,在富营养化水质提升、底泥内源污染物释放抑制和湖库生态修复方面具有技术优势和成功经验,在欧洲和世界各地已有众多的工程应用案例。对相关代表案例进行了介绍,在Steinbrunn湖体工程中,深水曝气的任务是降低盐度,并建立含氧量充足的深水层。Rundstedt湖体底部有大量固废填埋带来的污染物,深水曝气平台在运行后有效的抑制了铵在底层的释放。应用了深水曝气平台并经过20年监测的K-Teich湖工程,有力地证实了深水曝气平台在提升水质和生态修复方面的显著效果。最后对该技术在受污染的湖泊水库修复类工程的应用进行了总结和展望。

Integrated assembled deep water aeration systems(TIBEAN)for polluted lakes and reservoirs with thermally stratificated feature have been designed and operated for more than 25 years in Europe and provided a very effective solution for water quality management,sludge treatment and ecological restoration.A lot of projects have been implemented in Europe and around the world.Related cases are introduced.The tasks of the deep water aeration for Lake Steinbrunn were the reduction of the salinity and the establishment of a completely aerobic Hypolimnion.Lake Rundstedt had been filled with industrial disposals.After refilling water aerators were taken in operation to provide enough oxygen to avoid Ammonium release to the Hypolimnion.The K-Teich lake has been monitored during the last 20 years.The result shows that deep water aerator is effective for water quality improvement and ecological restroation.The application potentials are discussed and visions are made for polluted lake and reservoir restorations in the end.
