In the existing water treatment system, the float removal tank and the sediment removal tank are separately installed to separate and remove the floating and sediment introduced with the wastewater and wastewater. Therefore, the installation cost of installing the floating and sediment removal tanks separately is high. It has been pointed out that it takes a lot of money for maintenance because the installation cost is large and the installation area is large. Recently, as a means to solve this problem, a water treatment device capable of simultaneously removing floating and sediment from the integrated tank is practical. Although it was proposed as a Model No. 170219, it is not possible to remove the float attached to the float separation screen for collecting the float during the treatment of the wastewater, resulting in clogging of the screen, thereby reducing the treatment efficiency. There is also a separate section of the screen That of the contaminated water from the suspension, so that thereby the discharge does not process the water flows out is discharged dehydration standing unsanitary that will contaminate the work environment has been pointed out as a problem.

First, the suspended matter filtration device 5 will be described.

The suspended filtration device 5 is rotatable while being installed in the longitudinal direction of the raw water inlet 52 and the raw water inlet 52 and the water treatment tank 1 installed above the raw water inlet side of the water treatment tank 1. The raw water inlet 53 and the raw water inlet 53 are protruded on one side wall of the raw water inlet 52 and connected to an introduction pipe (not shown) for introducing raw water from the outside. 53 is a "U" shaped so that the raw water inlet chute (54) for guiding the raw water flowing into the drum screen 51, and the raw water guided to the raw water inlet chute (54) can be introduced into the drum screen (51) At least one horizontally installed support wall 55 having an inflow passage, a screen-rotating motor 56 fixedly attached to the other wall surface of the raw water inflow portion 5, and an upper portion of the drum screen 51; Consisting of a water spray pipe 57 for injecting water toward the drum screen 51 It can control.

Next, the above-mentioned floatation apparatus 6 will be described.

The float collecting device 6 penetrates the central portion of the drum screen 51 in the axial direction, and is fixedly supported by a support 61 fixedly installed in a cross state above the raw water inlet chute 54, and the other end of the raw water inlet part. The circumference of the drum screen is assembled with the screw casing 62 installed in the state protruding from the other wall surface of the 52 and the opening formed in the tip portion of the screw casing 62 located inside the drum screen 51. A plurality of hoppers 63 are formed in a state in which they are opened in both directions in the direction and are formed in a middle portion of the screw casing 62 which is located outside of the other wall surface of the raw water inlet 52. A water discharge container 64 having a discharge hole 621 and a discharge port 641 for collecting and discharging the water discharged to the discharge hole while covering an intermediate portion in which the discharge hole 621 is formed, and the screw casing ( 62) Float discharge port for discharging the floating material conveyed from the floating material compression screw 66 and the floating material compression screw 66, one end of which is supported by a bearing or the like and the other end is connected to the floating material compression motor 65 while being rotatably installed therein. 67).

The screw formed in the floating compression screw 66 in the above is formed in a narrow pitch, the pitch of the screw located inside the drum screw 51 is wide, while the water discharge container 64 The screw from to the view artifact discharge port 67 has a narrow pitch so that the view artifact conveyed to the screw of the wide pitch in the drum screen 51 is compressed in the process of being conveyed to the screw having a narrow pitch to the float. The water contained in the water is squeezed, and the water squeezed by the compression action is collected in the water discharge tank 64 through the discharge hole 621 and discharged to the water treatment tank 1 through the discharge port 641 and the water is discharged. The suspended matter is discharged to the suspended matter outlet 67.

On the other hand, both sides of the drum screen 51 is rotatably supported by a bearing or the like at the free end side and the middle of the screw casing 62, and on one side (right side in the drawing) of the drum screen 51 An interlocking chain gear 58b to which the chain 58 extended to the drive chain gear 58a of the screen rotating motor 56 is connected is provided.

And the screw rotation motor 56 is configured to drive by a water level sensor not shown in the figure. That is, the screw rotation motor 56 is not normally driven, but the floating water introduced together with the window water introduced into the raw water inlet 53 is filtered at the bottom of the drum screen 51, and thus the raw water introduced. When the water level is not stored smoothly to the drum screen is stored when the stored water level reaches the appropriate level, the water level sensor is configured to drive the screen rotation motor 56 to detect the water level.

Another feature of the present invention is to allow the drum screen 51 to be divided and assembled into a plurality of split screen 51a divided into pieces.

To this end, each of the split screens 51a may be assembled in a circular shape or separated from each other by screwing the fastening bolts 71 in a state where each end is interposed between the inner and outer assembly members 7a and 7b. The inner assembly member 7a is protruded toward the center of the drum screen 51 so as to transfer the float upwards and fall to the hopper 63 so as to be replaced. (See Figs. 5 and 6).

Each of the split screws 51a has a structure in which wavy metal wires are coupled at tight intervals.

Another feature of the present invention, the discharge of the treated water discharged through the discharge passage 17 formed in the treated water collecting unit 16 formed at the front end of the treated water outlet 11 of the water treatment tank 1 The treatment water discharge gate 7 to be adjusted is installed in such a way as to be capable of raising and lowering up and down.

The female thread member 74 is screwed to the spiral lead 73 formed on the rotating shaft 72 of the lifting handle 71 which is rotatably installed left and right in the water treatment tank 1. Is attached (see Fig. 7).

Therefore, by rotating the lifting handle 71 to the left or right, the treated water discharge gate 7 is raised or lowered to adjust the discharge water level of the discharge passage 17 to adjust the discharge of the treated water.

On the other hand, in the present invention, the transfer motor 31 for rotating the sediment feed screw (3), the motor 42 for carrying out to rotate the sediment discharge screw (4), the drum screen 51 of the suspended matter filtering device (5) The motor for screen rotation for rotating the motor 56, the motor for floating float compression screw 65 for rotating the float compacting screw 66 of the float collecting device 6, and the like are used in which a speed reducer is integrally formed.

Referring to the operation of the present invention configured as described above are as follows.

The raw water introduced through the raw water inlet 53 is introduced into the drum screen 51 of the suspended solids filtration device 5 through the raw water inlet chute 54. In this case, particles such as soil or sand introduced together with the introduced raw water are introduced. The small sediment passes through the wavy metal wires of the split screen 51a, which forms the drum screen 51 like raw water, falls into the water treatment tank 1, and the particles are larger than the above-mentioned sediments. The foreign matter and suspended matters do not escape the drum screen 51 and remain filtered on the drum screen.

As described above, the particles having a high specific gravity among the sediments such as soil and sand introduced into the raw water through the drum screen 51 immediately sink to the bottom of the water treatment tank 1, but the particles having a light specific gravity are the water treatment tank (1). The raw water introduced into the sink slowly sinks while moving toward the treated water outlet 11, and thus the sediment sinked to the bottom of the water treatment tank 1 is the tank protrusion 12 by the sediment transfer screw 3. After being transported toward the cylindrical part 13 by the sediment discharge screw (4) is discharged to the outside through the discharge port (15).

On the other hand, the suspended solids are introduced into the raw water inlet 53 together with the raw water and continuously filtered in the drum screen 51 of the suspended solids filtration device 5 so as to accumulate on the bottom side of the drum screen. When the water level sensor (not shown) detects the water level when the water is stored at the water level, the floating water compression motor 65 of the screen rotating motor 56 and the floating water collecting device 6 is driven for a predetermined time. .

When the screen rotation motor 56 of the float filtering device 5 is driven to rotate the drum screen 51, the protruding pieces 72 of the inner member 7a which couple the respective split screens 51a to each other are coupled. This float is moved upwards, and when the protrusion piece 72 is rotated above the hopper 63, the float falls by its own weight and falls into the hopper 63, and also the water spray pipe 57 Float is washed away by the water sprayed from the) to the drum screen 51 to pass through the hopper 63 is rotated to be completely suspended state.

And the floats dropped to the hopper 63 as described above is moved to the float discharge port 67 by the float squeezing screw 66 which is rotated by the drive for the float squeezing motor 65, the floating squeezing screw ( 66 is a screw that is located on the drum screen 51 has a wide pitch while the screw is located between the float discharge port 67 from a position outside the drum screen 51, that is, from the tip of the water discharge container 64. Since the pitch of the narrow state of the floating material flowing into the hopper 63 is compressed as the screw pitch narrows in the process of being transferred to the water discharge container 64, the water contained in the floating material as the floating material is compressed in this way While being squeezed and collected in the water discharge tank 64 through the discharge hole (621) is discharged to the water treatment tank (1) through the discharge port 641, the floating water is removed, the float discharge port (67) Through it will be discharged to the outside.

When the suspended solids filtered on the drum screen 51 of the suspended solids filtration device 5 as described above are dropped to the hopper 63 of the suspended solids collecting device 6, the screen rotation motor 56 is completed. Is stopped, and when the floating material introduced into the hopper 63 is completely discharged, the floating compression motor 65 is also stopped to wait for the next operation signal.

And the raw water introduced into the water treatment tank (1) is discharged to the treated water outlet 11 in the sediment is settled, the amount of raw water flowing into the water treatment tank (1) to increase the discharge of the treated water In order to reduce the storage water level by lowering the treated water discharge gate 7 by rotating the lifting handle 71, the treated water is discharged in large quantities through the discharge passage 17 in which the stored water level is lowered. When the amount of raw water flowing into the water treatment tank 1 is small to reduce the amount of treated water, the lifting handle 71 is rotated to raise the treated water discharge gate 7 so as to store the water treatment tank 1. The higher water level will reduce the amount of treated water.

On the other hand, as described above, the suspended solids are intermittently rotated one by one every time the suspended solids are filtered to some extent in the drum screen 51 of the suspended solids filtration device 5 while squeezing water through the suspended solids collecting device 6 and discharged. In the process of making a deformation (opening phenomenon) occurs in the wavy metal wire formed on any one or more of the divided screws 51 of the divided screens 51 constituting the drum screen 51 to reduce the filtration function of the suspended matter. The screw is then removed by unscrewing the fastening bolts 71 of the inner and outer assembly members 7a and 7b (see the imaginary line section of FIG. 6), and then deforming the deformed metal wire. Compared to removing the entire drum screen 51 and correcting the deformed metal wire or replacing the entire drum, the drum screen 51 can be corrected or replaced with a new one. To reduce the costs required for correcting and replacing the deformed portion of the screen may also exhibit the characteristics of being able to shorten the time and labor.

According to the present invention as described above can be installed in the longitudinal direction of the water treatment tank is installed in the suspended solids filtration device for separating and removing the sediments and solid suspended solids, such as soil, sand contained in industrial water and waste water. The overall volume of the debris separation and removal device can be reduced to effectively utilize the location where the water treatment device is installed. Also, the drum screen of the suspended filtration device has a circular shape of the divided screw manufactured according to a standard. In case of abnormality (phenomena occurring in the state of dense metal wires) in a part of the drum screen, it is possible to separate and correct or replace only the corresponding screw that has been abnormally corrected and replaced. To reduce the cost of replacement and replacement, Since the discharge of the treated water can be controlled in proportion to the inflow of raw water, it is possible to improve the treatment efficiency of the raw water.
