4种景观水体太阳能推流方式复氧效果研究

Study on Reoxygenation Effect of Four Solar Energy Push Flow Modes in Landscape Water

以非晶硅太阳能电池板为太阳能动力,以南方某社区典型景观水体为对象,开展水池静态试验,研究了4种不同太阳能推流方式:水下30 cm水平推流、水下5 cm(水面)水平推流、水下5 cm(水面)向上推流和在推流器叶轮后方安装进气管推流对景观水体的复氧效果。研究结果表明:在推流器叶片后端安装进气管的推流方式的复氧效果优于其他3种方式,水面向上推流优于水面水平推流,水下推流对溶解氧的提高作用最小,但却能最大范围内扰动水体,改善水体流场环境。

Taking amorphous silicon solar cells as solar power and a typical southern landscape water as study object,reoxygenation effect of four different solar energy push flow modes were researched.The four modes including horizontal push flow 30 cm under the water surface,horizontal push flow 5 cm under the water surface,upward push flow 5 cm under the water surface,installing a intake pipe behind the vane of the mixer.The results indicated that installing a intake pipe behind the vane of the mixer is the most effective mode,and then the surface upward push flow is better than the horizontal push flow.Horizontal push flow 30 cm under the water surface is the most useless mode for dissolved oxygen improving,but very effective in improving the hydrodynamic environment of landscape water.
