The present invention relates to a water treatment apparatus, and more particularly, to an unmanned synthetic water treatment apparatus in which all water treatment processes are performed in one process.

In general, the pretreatment facilities for treatment devices such as water, sewage, village sewage, and wastewater have been recognized as having extensive facility area, huge facility cost, many equipment and manpower, and need to be constructed for many years. Because of the huge cost, the water treatment plant has been installed in a small capital factory or plant, but it was difficult to install due to excessive initial investment.

Contaminants present in water are treated by physical chemical or biological methods. When explaining the rough treatment method, the removal of large particles of suspended solids contained in the inflow pipe of sewage wastewater, etc. is primarily removed from the screen tank, and after passing through the immersion tank, the pollutant concentration and flow rate are adjusted in the flow adjustment tank. In the first settling tank, the precipitate is induced, and the activated sludge tank, the denitrification tank, and the second settling tank are allowed to pass through, and then the aeration of the microorganisms in contact with the microorganism contact material is caused by aeration of air in the activated sludge tank. .

In addition, the microbial mass is decomposed by self-extinguishing while proliferating organic contaminants contained in the influent as a nutrient component, in the denitrification tank to remove the nitrogen components contained in the influent through the activated sludge tank nitric oxide removal do.

Thereafter, the microbial masses grown in the secondary settling tank are precipitated, and the treated water corresponding to the supernatant is sent to the treated water tank, and a part of the secondary sludge precipitated is returned to the activated sludge tank. The treated water sent from the secondary settling tank consists of a process that is temporarily stored in the treated tank, finally disinfected in the disinfection tank, and then discharged.

In this process, since each process from the screen tank to the disinfection tank is installed separately, the area occupied by the structures corresponding to each process is so large that a lot of sites are used. There was a problem that cost increase and maintenance is difficult.

The unmanned comprehensive water treatment apparatus of the present invention includes a main body structure 10, a surface aeration unit 20, a driving unit 30, the screen unit 40, sediment collecting unit 50, the conveying means 60, raw water supply unit 70 ), And the contaminant collecting unit 80, the body structure 10 is a scraper guide U-shaped tube 52 is formed on both sides of the lower side, the sediment hopper isolation wall 51 in the middle portion of the scraper guide U-shaped tube 52 It is formed to protrude upwards. The inclined screen 41 is fixed to one side of the inner wall of the main body structure 10 so as to be inclined, and the oscillation spring 43 is installed between both ends of the inclined screen 41 and the inner wall of the main body structure 10 so as to swing. The part 40 is comprised.

When the inclined screen 41 is installed on the main body structure 10, a portion of the upper end of the inclined screen 41 is installed to be exposed to the surface of the water to collect floating impurities in the exposed portion.

The collection tank 81 is installed at the upper end of the inclined screen 41 to collect the impurities. The collection tank 81 separates the contaminants 5 by installing a floating contaminant collecting weir 83, and the supernatant is separated by the supernatant collecting weir 84 installed at the upper boundary of the structure. Floating contaminants collection weir (83) to install the contaminant separation screen collection weir (82) to collect the contaminants into the collection tank (81).

Floating contaminants collected from the upper layer is accumulated in the collection tank 81 by separating only the contaminants from the water through the floating contaminant collecting weir 83 installed slightly above the water surface. One end of the collection tank 81 is inclined to facilitate the collection, the end is connected to the chain link-type scraper 64 by installing the opening and closing port. Therefore, the collected contaminants are integrated in the storage container 63 through the drive frame along the chain link scraper 64 and through the screw type dehydrator 90 like the sediment transported from the bottom.

The screen trust 42 is provided to be spaced apart from the inclined screen 41 by a predetermined distance. The screen trust 42 hits the bottom when the inclined screen 41 swings, and the contaminants caught in the inclined screen 41 are separated from the inclined screen 41 by the impact. The screen trust 42 is installed within the swing distance of the inclined screen so that the inclined screen collides.

One end of the turnbuckle 23 is fixed to the center of the inclined screen 41, the turnbuckle 23 is formed so that the spring 22 and the connecting ring is installed to vibrate up and down. The other end of the turnbuckle 23 is fixed to the end of the cylinder rod 32 of the cylinder 31, the cylinder 31 is interrupted by the solenoid valve 33 to be repeated up and down movement. The cylinder 31 is connected to the control unit 34 to control the driving, and repeatedly drives the set operation.

Brush off dirt and dirt. This moves the contaminants in the upward direction of the inclined inclined screen 41 while shaking off the contaminants while vibrating by the springs 22 and 43, as shown in FIG. Suspended sediments accumulate inside the slope screen and accumulate in the upper layer above the water surface.

Although the cylinder and the solenoid valve are used as the vertical movement means of the inclined screen 41 in the embodiment of the present invention, the present invention is not limited thereto.

The sediment collecting unit 50 is formed at the lower portion of the main structure 10 to collect sludge and sediment that sinks from sewage or sewage, and the sediment collecting unit 50 has a sediment hopper isolation wall 51 inclined at the center thereof. The scraper guide U-shaped tube 52 is formed on both sides as a center. The scraper guide U-pipe 52 is installed so that the chain link-type scraper 64 used for the conveying means 60 discharges the sludge settled.

Sewage sewage and the like is supplied to the raw water supply unit 70 through the inlet pipe 71 connected to the inlet pipe (1). The raw water supply unit 70 is installed above the sediment collecting unit 50, the raw water supply unit 70 forms a raw water distribution unit 72 formed at the end of the inlet water pipe 71, raw water distribution unit 72 Fed down through. In addition, since the raw water distribution unit 72 is formed to be separated on both sides of the sediment hopper isolation wall 51, the inflow water flows to both lower portions.

As shown in FIG. 5, the inflow water flowing into the inflow water pipe 71 may be guided in a desired direction through the raw water distribution unit 72, which is a transfer table in the form of a V-shaped groove 73. The raw water distribution unit 72 is fixedly attached to the lower end of the center of the point where the influent pipe 71 and the V-shaped feeder are in contact with each other, and the gap is maintained at 3/5 to 3/4 of the minimum inlet pipe diameter to smoothly flow the water. do. The specification of the raw water separator of the raw water distribution unit 72 is 1.5D of the inflow pipe diameter, so that the inflow of the inflow pipe induced by the flow rate may cause continuous blockage by pressurization and contaminants, etc. Neat surface treatment is required.

The influent flows down and the light contaminants and Ascending up, heavy sedimentation light and sludge go down and gather into scraper guide U tube (52). The collected sludge is transported by the chain link scraper 64 and collected in the storage container 63. The chain link type scraper 64 is driven by the scraper driver 61, and the screw dehydrator 90 and the discharge end 91 are formed at the end of the scraper driver 61.
