最近,日本开发出了“水库水流控制装置”技术,用于对付水库富营养化。整个系统由循环流动装置、人流和出流装置等组成。其中主要设备是循环流动装置,它是～个安装于库底的扩散式充气装置,通过吹入空气使上层库水与中下层库水进行掺混,形成一15～20m深的水温均匀的混合层,这样,既降低了表面水温,又使光线不能达到较深的中层,从而减少了藻类生长所需的光合作用,若再配以人流
Recently, Japan has developed a “reservoir flow control device” technology to deal with reservoir eutrophication. The entire system consists of circulating flow device, flow and outflow devices and other components. The main equipment is a circulating flow device, which is a diffusion inflator installed at the bottom of the reservoir. The air in the upper reservoir is mixed with the reservoir water in the middle and lower reservoirs to form a uniform water temperature of 15-20 m Layer, so that not only reduces the surface water temperature, but also make the light can not reach the deeper middle, thereby reducing the algae growth required for photosynthesis, if we add to the flow of people
