Description

A sludge scraper for a sedimentation tank

technical field

The utility model relates to water quality purification technology, in particular to a mud scraper for a sedimentation tank.

Background technique

The main body of the sewage treatment system adopts the Carrousel 2000 oxidation ditch process. The main treatment facilities include grilles, influent lift pumps, selection tanks, oxidation ditch, final sedimentation tanks, etc. The main pollutants discharged are COD and ammonia nitrogen. The discharged water complies with the Discharge Standard of Water Pollutants for Urban Sewage Treatment Plants (BD11/890-2012), and is finally discharged into the Xiaozhong River. The sludge is dehydrated by a belt filter press and then treated in a harmless manner.

There are currently 2 sets of final sedimentation tanks in the East Purification Station, with sludge scrapers and sludge collection buckets. The mixed liquid discharged from the oxidation ditch enters the standpipe in the center of the tank through the water inlet pipe under the deflector, and enters the water inlet distribution cylinder through the water outlet at the upper end of the standpipe, and the distribution cylinder makes the water flow evenly into the secondary sedimentation tank. The supernatant after precipitation overflows to the outlet weir through the overflow weir with V-shaped grooves located around the pool. The sludge that sinks on the bottom of the pool with a certain slope is scraped off by the scraper and collected in the sludge hopper. The sludge flows from the sludge hopper into the sump of the return pump and is returned to the selection sump.

Due to the N and P indicators in the effluent water quality, there will be moss and green algae on the wall of the pool in the effluent weir, which will affect the appearance of the pool on the one hand; In order to ensure the stability of the effluent, manual cleaning is adopted for on-site treatment, which is labor-intensive and unstable.
