The present invention relates to a sedimentation basin for removing the sediment of raw water introduced into the wastewater treatment plant for the first time, in particular, the waste water to be discharged to the outside while forcibly settling and then turning the sand or other minerals contained in the raw water The present invention relates to a sediment removal device for treatment plant sedimentation paper.

In general, as shown in Figure 1, the wastewater treatment plant 100 filters out impurities including various organic and inorganic substances contained in inflow water, and an inlet dong (110, hereinafter referred to as a settlement) that catches a relatively large material among impurities. And, the sedimentation basin 120,140 and the aeration tank 130 to filter the medium size of the material passing through the settlement 110, and the filter 150 for filtering the fine material passing through the final settler 140 is configured.

In addition, the sedimentation site 110, the crude wood screen 111 for filtering the floating water flowing through the raw water inlet pipe, and the acupuncture lifter 112 for removing inorganic matters such as sand or soil filtered by the crude wood screen 111 And, the fine screen (113) for filtering the fine suspended matter through the sedimentation lifting device 112 is configured.

Therefore, various kinds of desorption apparatuses for effectively removing the sediments and various inorganic substances such as sand flowing into the sedimentation basin 110 are used.

For example, as a sediment removal device, a device for discharging the sediment by installing a plurality of buckets at a predetermined interval on the chain moving by the caterpillar is used, but such a lifting device not only decreases the salvage efficiency of the sediment, It is easily worn and increases the cost of maintenance of the device.

In addition, as a sediment removal device, a device for discharging sand by putting a glove bucket into raw water is used, but such a lifting device does not remove the sediment continuously but intermittently removes the salvage efficiency. If this large amount is introduced, removal is difficult.

As a result, the untreated sediment damaged the equipment of the rear end and the entire treatment plant, resulting in a fatal lifespan, and the settling time also increases the number of working hours and working hours according to maintenance.

Therefore, the present invention was devised to solve the problems described above, by forcibly settling the sand or other inorganic matter contained in the raw water flowing into the wastewater treatment plant, and then turning by using a separate turning device It is an object of the present invention to provide a sediment removal device of a sedimentation basin for a wastewater treatment plant that can be treated by using a discharge device.
