The present invention relates to a sedimentation tank having an inclined plate assembly that maximizes the high-speed sedimentation and sedimentation efficiency of the sludge to purify the wastewater in the sedimentation tank for industrial and tap water. In particular, it is easy to install and replace the inclined plate, The present invention relates to a high-efficiency multi-sedimentation tank to facilitate separation from purified water and to increase sedimentation efficiency by increasing the strength of the inclined plate and widening the contact area with the water.

In the treatment for preventing water pollution, precipitation is called purifying or condensation by submerging suspended solids, that is, sedimentary solids, by gravity by gravity. In general, precipitation efficiency increases the separation efficiency of the suspended solids. In order to increase the separation area by inserting the inclined plate into the sedimentation basin.

Sedimentation tanks with inclined plates should theoretically install inclined plates in the sedimentation tank to shorten the settling distance for sludge suspended particles to shorten the sedimentation time and increase the effective sedimentation area to increase sedimentation efficiency per unit area.

However, due to inadequate design and maintenance in practical applications, the purified water containing sediment particles accumulated on the inclined plate or unseparated sediment flotation is discharged through the outlet of the sedimentation tank, thereby deteriorating the water quality.

In particular, such deterioration efficiency and maintenance problems in wastewater treatment plants in which there is a shortage of skilled workers naturally avoid the use of inclined plates, and even remove the inclined plates that are already installed.

In general, the most important in the swash plate for sedimentation of industrial and water wastewater is the sedimentation rate and the rigidity of the swash plate, that is, the efficiency of the swash plate for a constant amount of treatment.

In view of the above, a number of inclined plates have been developed so far, but since they are all similar structures, they have not escaped the limitations in sedimentation speed and sedimentation efficiency.

Conventional inclined plates all have parallel horizontal grooves formed in the plate to settle the sludge of the suspension, but the sludge stacked in the grooves is not concentrated in one place and is loaded in each groove, and even the turbidity suspension is high. If the sludge is loaded, there is a problem of sludge falling into the water to be treated when the sludge rolls down from the grooves of the plate body. There was a problem in the post-treatment because it could not be made, so the sedimentation efficiency was not good.

In addition, a plurality of inclined plates are partitioned into a predetermined space inside the settling tank, and wastewater, that is, a suspension mixed with purified water and sludge comes in from the inlet of the settling tank, and the sludge sludges down the settling tank through the plurality of inclined plates, and the purified water is discharged from the settling tank. In the general sedimentation tank composed of the principle, the problem is that the fine sludge particles contained in the suspension separated in the inclined plate adjacent to the purification water outlet in the sedimentation tank can be discharged to the outlet.

Another problem of the conventional settling tank is that the purification water discharge port is provided in the rear of the settling tank in the sedimentation tank to reduce the settling efficiency due to the increase in the flow rate of the purified water discharged to the outlet, the sludge cleaning attached to the inclined plate is insufficient to reduce the settling efficiency and corruption Due to the water degradation due to water pollution may be intensified.

The present invention has been made to solve the problems of the prior art as described above, to increase the sedimentation efficiency by increasing the water treatment area by manufacturing and installing a slope plate suitable for the installation of the sedimentation tank in the sewage or wastewater treatment process having a square shape The purpose is to maximize the treatment efficiency of sewage and wastewater by allowing the sedimentation tank to discharge a large amount of sewage and to discharge the purified water through the outlet of the sedimentation tank.

Another object of the present invention is to reduce the size of the overall sedimentation basin by reducing the size of the overall sedimentation basin by making and installing a sloped plate having a size suitable for the sedimentation tank in the sewage or wastewater treatment process having a square shape. In addition, it is intended to reduce the maintenance period as well as the cost by enabling a quick replacement when the equipment maintenance needs, such as the aging of the slope plate.
