[0002] Industrial wastewater includes production wastewater and sewage, which are wastewater and waste liquids generated during industrial production. They contain industrial production materials, intermediate products, by-products lost with water, and pollutants generated during the production process.

The stainless steel pipe is horizontally fixed at the lower end of the rear surface of the sediment collection box, the servo motor is vertically fixed above the middle section of the stainless steel pipe, the control valve is mechanically connected to the upper part of the front end of the stainless steel pipe, the sealing plate is bonded to the upper surface of the sediment collection box, and the handshake glue is connected to the center of the upper surface of the handshake. The utility model is provided with a sediment processor, so when the sediment in the sedimentation tank exceeds a certain amount, the sediment can be processed, which does not affect the normal use of the sedimentation tank and is convenient for people to process the sediment.

[0004] In the above-mentioned document, only opening the control valve is not enough to allow all the sediment separated during the treatment of radioactive industrial wastewater in the sedimentation tank to enter the sediment collection box through the stainless steel pipe, resulting in the residual sediment in the sedimentation tank always remaining and unable to be effectively treated. At the same time, the method for collecting and treating the sediment in the above-mentioned document adopts the method of grabbing the handshake, lifting the sealing plate, exposing the top of the sediment collection box, and then treating it. However, in this method, the cleaning personnel can only slowly collect the sediment in the sediment collection box with the help of tools. The fixed sediment collection box cannot perform fast and efficient sediment treatment work, which affects the efficiency of collection and treatment, and the residual water source in the recovered sediment will also be treated together, causing waste problems.

The threaded connection between the lifting plate 23 and the threaded rod 22 can drive the two connecting rods 24 to move downward, so that the four sides of the conical lower pressure plate 25 in the inner cavity of the separation sedimentation box 1 are pressed against the inner wall of the separation sedimentation box 1 and move downward until they are stuck in the guide inclined plate 11. The water source during descent uses the several leakage grooves 26 opened on the conical lower pressure plate 25 to reduce the resistance to the conical lower pressure plate 25, so that the sediment is finally concentrated in the discharge funnel 12. At this time, the liquid above the conical lower pressure plate 25 can be discharged through the separation liquid output pipe 15 by starting the electric control valve 16.

[0029] The sediment transported to the inner cavity of the filter collection box 4 through the lifting pipe 33 will fall into the sediment collection box 44 through the guide plate 42. When it needs to be collected, it is only necessary to open the movable door 41 and use the pull groove on the side of the sediment collection box 44 to pull out the sediment collection box 44 as a whole, and use the supporting inclined plate 43 to quickly slide it to the ground for easy processing. At the same time, the water contained in the sediment falling into the sediment collection box 44 will be filtered by the stainless steel screen 441 and flow downward, and finally flow into the bottom of the inner cavity of the filter collection box 4 through the holes opened in the stainless steel screen 441 and the gap between the two adjacent supporting connecting rods 47.

The water source during the descent uses the several leakage grooves 26 opened on the conical lower pressure plate 25 to reduce the resistance to the conical lower pressure plate 25, and finally the sediment is concentrated and pressed into the discharge funnel 12. At this time, the liquid above the conical lower pressure plate 25 can be discharged through the separation liquid output pipe 15 by starting the electric control valve 16. After the discharge, the butterfly valve 32 provided on the outer wall of the discharge pipe 31 can be opened to allow the sediment containing a small amount of wastewater to quickly pass through the discharge pipe 31 enters the lifting pipe 33, and then the motor 34 drives the screw rod 35 in the lifting pipe 33, so that all the sediments falling into the inner cavity of the lifting pipe 33 can be quickly transported upward, and the edge of the screw rod 35 is close to the inner wall of the lifting pipe 33 during transportation to avoid omission, thereby quickly transporting the sediment to the inner cavity of the filter collection box 4, and passing through the guide plate 42 and falling into the sediment collection box 44. When it needs to be collected, it is only necessary to open the movable door 41 and use the pull groove on the side of the sediment collection box 44 to pull the sediment collection box 44 out as a whole. , and uses the supporting inclined plate 43 to quickly slide to the ground for easy processing. At the same time, the water contained in the sediment falling into the sediment collection box 44 will be filtered by the stainless steel screen 441 and flow downward, passing through the holes opened in the stainless steel screen 441 and the gap between the two adjacent supporting connecting rods 47 and finally flow into the bottom of the inner cavity of the filter collection box 4.
