Here, the floating sedimentation induction means, one end is fixed to one side of the dissolved water porous baffle 105 of the floating sedimentation composite tank 110, the other end is induced to float the flocs attached to the micro-bubbles so that it is possible to overflow Located on the lower side of the upper surface of the floating sedimentation composite tank 110, the primary floating guide plate 101 is provided at an angle of 15 ° to 25 ° in the rear direction, and is located at the rear end of the primary floating guide plate 101. One end is spaced apart from the bottom surface of the floating sedimentation composite tank 110, and the other end is positioned higher than the other end of the primary floating guide plate 101 to be inclined at the same angle as the primary floating guide plate 101. It is installed by separating the fluid flow, the sedimentation induction plate 102 is provided to induce sedimentation of the floc that is difficult to float and flotation is difficult, and the first and second by being located at the rear end of the sedimentation induction plate 102 On the bottom surface between the car sedimentation hoppers 104 and 106 It is fixed, and the other end is formed at the same height as the other end of the primary floating induction plate 101, and thus is not injured as the fluid flow is rapidly changed by the sedimentation induction plate 102, and can be injured. It is composed of a secondary floating induction plate 103 provided to be inclined at the same angle as the primary floating induction plate 101 so that it is possible to re-induce the re-injury.

In addition, in the upper end of the other end of the sedimentation induction plate 102, the injured sludge by securing the floating sludge transfer section 107 by adjusting the water level adjusting device 117 by an operator confirming a change in water level is an injured sludge. The removal device 109 and the sedimentation induction plate 102 are broken into suspended solids, and a direction changing angle 114 is further provided 30 to 60 mm lower than the water surface so as to be prevented from being converted into the original raw water form. The inlet pipe of 120 is further equipped with an inflow flow meter 100 to measure the inflow flow rate, and the coagulation tank 130 is further equipped with a pH indicator controller 130-2 for adjusting the hydrogen ion concentration. On the bottom surface of the treated water storage space 112 formed on one side of the treated water storage space 112, an outflow flowmeter 170 is further installed to measure the outflow flow rate.

The rectangular high-efficiency pressurized solid-liquid separation water treatment device utilizing the vortex-type micro-bubble generating device according to the present invention made as described above is introduced into the rapid reaction tank 120 as shown in FIGS. A certain amount of inorganic coagulant is injected into the rapid reaction tank 120 from the tank 121, and a high-speed stirring device is used to stir it to promote sufficient contact reaction between the inorganic coagulant and the suspended solids in raw water to aggregate the suspended solids. (130).

The raw water transferred to the flocculation tank 130 in order to make it into an appropriate form for floating by contact with the micro-bubbles increases the size of the floc aggregated by the polymer coagulant supplied from the polymer coagulant chemical tank 131, and at this time, slow stirring It is supplied to the floating sedimentation composite tank 110 by stirring at a low speed with the device so that the flocculated flocs are not broken.

Separately, in the vortex-type micro-bubble generation unit (KDR) 140 having a two-stage complex structure, a part of the treated water is introduced into the vortex-type micro-bubble generation unit 140 and vortex using an air compressor 141. By supplying air to the micro-bubble generation unit 140, the treated water and air are mixed in the vortex-type micro-bubble generation unit 140 inside the vortex formation section to form a vortex, and the pressure is increased from the centrifugal force caused by the vortex. It dissolves in the treated water to make dissolved water, and then lowers the pressure in the vortex removal unit to form microbubbles, and the higher the pressure according to Henry's law, the higher the solubility of air, so that the treated water is vortex-type microbubble generator 140 In addition to controlling the speed of inflow, the intensity of the vortex is also controlled, so the pressure generated accordingly can be adjusted, so that the solubility of air in the treated water can be controlled. The amount of micro-bubbles in the seawater can be adjusted, and the opening / closing ratio of the supply valve for supplying from the vortex-type microbubble generating unit 140 to the floating sedimentation composite tank 110 is controlled to internal the vortex-type microbubble generating unit 140 It is a device that can control the size of micro bubbles by controlling the pressure of.

The raw water of the flocculation tank and the dissolved water of the vortex-type microbubble generating unit 140 flow into the floating sedimentation complex tank 110. At this time, by installing the molten water porous baffle (105) at the rear end of the dissolved water supply pipe at the bottom of the flow of raw water, it prevents the flocculation from breaking and prevents the flocculation from breaking. 110) The number of effective contacts with flocculated flocs is made more frequently and smoothly by distributing evenly.

The microbubble-attached floc installs the primary floating induction plate 101 to induce injury.

In order to separate the floes floating in the water due to the high flocculation and the high specific gravity, the sedimentation induction plate 102 and the direction changing angle 114 fixed to the sedimentation induction plate 102 are installed 45 mm lower than the surface of the fluid. By separating the flow in the forward and reverse directions, the injured flocks are floated in the flotation sludge transfer section and collected in the flotation sludge, and the non-floating material induces sedimentation easily due to complete loss of buoyancy due to the sudden change of fluid flow.

The sedimented floc is deposited on the primary sedimentation hopper and is automatically discharged by a motorized valve at regular intervals and the fluid flows back to the original flow. The material induces re-injury.

The treated water from which the solid liquid is separated is sent to the treated water storage space 112 through the treated water discharge pipe, and additional sedimented substances are deposited in a secondary sedimentation hopper and discharged at regular intervals.

In the storage water storage space 112, a certain amount is sent to the vortex-type micro-bubble generating device to become dissolved water and the rest is discharged.

The floating sludge exists in the floating sludge transfer section 107 of 30 ~ 60mm between the upper part of the floating sedimentation composite tank and the sedimentation guide plate, and is discharged separately by the floating sludge removal device 109. In order to prevent the sludge injured by the bumps from being broken back into floating materials and returning to the original raw form, the effective water level at the top of the turning angle is increased by 30 ~ 60mm depending on the flow rate, flow rate, and the amount of sludge generated when operating the floating sludge transfer section. It is variable and controlled by the water level control device to drive.

Therefore, the rectangular high-efficiency pressurized solid-liquid separation water treatment device (SDAF) utilizing the vortex-type micro-bubble generating device according to the present invention compensates for the disadvantages of the individual flotation device and sedimentation device by simultaneously floating and sedimentation in one device. By reducing the size and volume of the equipment and separating the fluid flow without additional power to induce sedimentation in the reverse direction, it is possible to save energy and at the same time be applied for multiple purposes regardless of the proportion of pollutants floating in the raw water.
