<p>PURPOSE:To increase water diffusion and flow speeds and to purify sludge water by aeration, by providing a drive apparatus for increasing the flow speed of water and an air discharge apparatus for discharging colloidal air to the vicinity of the drive apparatus. CONSTITUTION:The submerged fan of the drive apparatus 4 provided to the bottom of a canal wherein a water current is slow and an air treatment machine 10 is operated to supply air to an air supply nozzle 8. Hereupon, the driven submerged fan 7 forcibly sends out the water of a water channel from a water take-in port 5 to a discharge port 6 to promote the rapid flow-down water. The air supplied to the nozzle 6 becomes colloidal air to be dispersed into the water and receives the water current by the drive apparatus to be diffused. By this method, the flow speed of water can be increased without obstructing water-borne traffic and sludge water can be purified by aeration.</p> |
