VERTICAL CURRENT-SWITCHING DEVICE FOR WATER-TREATMENT CHANNELS

摘要

The present invention relates to a vertical current-switching device for water-treatment channels such as artificial wetlands, reaction tanks which take the form of water-treatment channels, water channels which provide connections between water-treatment facilities, and ecological channels; the vertical current-switching device being devised so as to be able to exchange the treatment water flow in an upper part and the treatment water flow in a lower part of the water channel, not only without a separate bypass channel but also without any pressurizing or water pumping facility; wherein the upper part and the lower part of the water channel each comprise a pair of inclined transverse plates which are provided transverse to the water channel at a predetermined incline and are provided symmetrically to each other about their mutual central line, and a pair of triangular flat plates connecting the lower edge of the upper inclined transverse plate and the upper edge of the lower inclined transverse plate. The present invention allows straightforward and rapid construction of vertical current-switching water channels and hence makes it possible to obtain the advantageous effect that water-treatment efficiency is improved by employing the unpowered vertical current-switching water channel in water-treatment facilities of diverse types.
