  Usually   sewage treatment plants  use a two-step process of sludge concentration and sludge dehydration to reduce sludge volume and volume. For sludge with a moisture content greater than 98%, concentration should generally be considered to reduce the moisture content to about 96% to reduce the sludge volume and facilitate subsequent treatment. Sludge concentration mainly increases the solid content of the sludge through the gravity concentration tank. However, through the concentration tank, the volume is proportional to the concentration time, and the sludge is left to stand and concentrate for a long time, and the organic matter in it is easy to decay under the action of microorganisms. It smells bad and affects the sanitary environment of the sewage treatment plant. Therefore, generally after the moisture content is reduced to 94-96% through gravity concentration, a mechanical dehydration process with higher dehydration efficiency is needed to further process the s...

  The   central drive sludge scraper   adopts central drive and suspension type. After the sewage flows into the diversion tube from the inlet pipe under the working bridge and diffuses, it flows out evenly and radially to the periphery. The suspended sludge is deposited on the bottom of the pool after sedimentation. The drive The device drives the central vertical shaft to rotate, and drives the scraper arm and scraper plate to rotate. After scraping the sludge from the periphery of the pool to the central sludge collection tank, it is discharged out of the pool through the sludge discharge pipe based on the hydrostatic pressure in the pool. The skimming device skims toward the edge of the pool, and then scrapes the slag rake into the slag discharge hopper and discharges it out of the pool; while the supernatant liquid overflows into the outlet water tank through the triangular outlet weir plate and is discharged.   Main features of the equipment :   The drivin...
