The Ramera sedimentation tank is also known as the inclined plate sedimentation tank. Good at efficient combined sedimentation tanks; A plurality of dense inclined pipe fillers are provided in the sedimentation tank area to precipitate the impurities suspended in the water, the water flow rises along the inclined pipe, and the separated sludge is discharged by gravity along the inclined pipe down to the bottom of the pool, and is concentrated and discharged. The pond can improve the sediment efficiency by 60 to 70%, and the processing capacity can be increased by 3 to 5 times in the same area. According to the original wastewater test report, the inclined plate sedimentation tank device with different flow rates can be designed, and a certain amount of flocculant usually needs to be added.
