Wind-powered self-cleaning system for stagnant water lake
2014
The invention discloses a wind-powered self-cleaning system for a stagnant water lake. The wind-powered self-cleaning system comprises a wind-powered lifter arranged at the lowest position in a stagnant water lake and a wetland processing system, wherein the wind-powered lifter is connected with the wetland processing system through a water conveying pipe; the wetland processing system comprises a water distribution pipe; a lawn is laid on the water distribution pipe; a soil layer is laid below the water distribution pipe; a plurality of branched water collecting wells are distributed below the soil layer; a plurality of adjacent branch water collecting wells are converged to a master water collecting well; a water discharging pipe for leading out water is arranged on the sidewall of the master water collecting well; an impervious barrier is arranged at the bottom of the master water collecting well; the water discharging pipe is connected back to the stagnant water lake; the water conveying pipe is connected to the water distribution pipe; and the stagnant water lake is connected to a rainwater accumulating tank through a lifting pump and a water pipe. In the wind-powered self-cleaning system disclosed by the invention, the wind-powered lifter is used for sending water from the stagnant water lake to the wetland processing system and then water enters the water distribution pipe so as to meet the growth requirement of the lawn; the water permeates into the soil layer and is purified by the soil, then is collected in the master water collecting well, led out through the water discharging pipe and finally discharged to the stagnant water lake, thus the water quality is purified, the cost is low and the effect is good.
