SOLID-LIQUID FLOTATION APPARATUS USING DIRECT INJECTION

摘要

The present invention relates to a floating-type solid-liquid separating apparatus using direct injection. The apparatus includes: a reaction tank which adds an inorganic coagulant to the entering fluid, stirring the mixture with a reaction stirrer to initiate a mixture reaction, and generates flocs; a floating pressure tank including a connection pipe which is installed on the lower part to be connected to the reaction tank and draws in the fluid including the flocs from the reaction tank, a floating guide plate which is formed in a tilted shape to induce the flocs attached with fine air bubbles to flow upward, a scum skinner conveying and removing the scum collected to the upper part, and a processed water discharge pipe which is installed to be connected to a processing tank to discharge the processed water undergone a solid-liquid separation process to the processing tank; the processing tank which draws in the processed water undergone a solid-liquid separation process by the floating pressure tank through the processed water discharge pipe; an air bubble supply means which directly supplies the pressurized water having compressed air dissolved therein to the floating pressure tank through the direct injection pipe connected to the lower part of the floating pressure tank to generate the fine air bubbles and floats the flocs to the upper part; and a control unit controlling the operation of the apparatus.
