いう問題が生じる。(Prior Art) Generally, lower water such as in a reservoir is an anoxic layer in which the amount of dissolved oxygen is close to zero due to the accumulation of organic substances and the generation of methane gas. In addition, in summer, because the lower layer water is lower temperature than the surface water, natural convection with the surface water occurs,
Therefore, if such dead water is discharged downstream, the bottom layer becomes dead water and no living organisms can live there, and a problem arises in that a foul odor is emitted and complaints are lodged by river basin residents.
