UPPER LAYER AND LOWER LAYER WATER MIXING TYPE WATER CLARIFICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To assure a density flow by enabling arbitrary changing of mixing ratios of upper and lower layer waters in clarifying water quality by sucking the upper and lower layer waters of a water area and by discharging the waters after mixing the waters so as to attain a density (density flow) equal to the density of the waters in which spouts exists.

SOLUTION: An upper conduit having an upper intake in its upper part and a conduit having a lower intake in its lower part are connected to each other through casings with the spouts formed on the outer periphery in-between. The upper and lower conduits are hung in a perpendicular posture under a water surface by means of wires etc., from a floating body floated on the water surface. Forcibly driven impellers are housed into the casings and the upper layer water and the lower layer water are sucked from the respective intakes and are discharged from the spouts. The casings of such water clarification system are vertically divided and the two impellers driven by separate driving sources are housed into the respective casings.
