AERATION CIRCULATION SYSTEM AND OPERATION METHOD THEREOF
PROBLEM TO BE SOLVED: To effectively prevent the occurrence of a thermocline and a eutrophication phenomenon in a water reservoir while suppressing a running cost.SOLUTION: An aeration circulation system that prevents the occurrence of a eutrophication phenomenon by blowing pressure air into a bottom part of a water reservoir to perform aeration comprises: a control part that controls operation on aeration work; water temperature meters that are set at the vicinity of a surface layer of the water reservoir and at the water depth of 3-5 m, respectively; calculation means that calculates a surface water temperature gradient in the water reservoir based on the water temperature information from the water temperature meters; and warning means that warns about the occurrence of a eutrophication phenomenon when the calculation result and the water temperatures of the water reservoir measured by the water temperature meters satisfy predetermined conditions. The control part starts the operation on aeration work in accordance with actuation of the warning means.SELECTED DRAWING: Figure 2
【課題】ランニングコストを抑えつつ、貯水池内での水温躍層および富栄養化現象の発生を効果的に防止可能とする。【解決手段】貯水池の水底部に圧気を吹き込んで曝気することで富栄養化現象の発生を防止する曝気循環装置であって、曝気の作業に関する運転を制御する制御部と、貯水池の表層付近および水深３ｍ〜５ｍの位置に各々設置される水温計と、各水温計による水温情報に基づき、貯水池の表層水温勾配を算出する算出手段と、算出手段の算出結果と、各水温計による貯水池の水温と、が所定条件を満たした場合に、富栄養化現象の発生を警告する警告手段と、を備えている。そして、制御部は警告手段が作動することに起因して、曝気の作業に関する運転を開始する。【選択図】図２
