Abstract

The invention discloses an aerated grit chamber for sewage treatment, which mainly comprises a treatment tank, a feeding port is formed in the top of the treatment tank, a discharging pipe is arrangedon one side of the treatment tank, a smashing shaft is vertically and rotationally connected into the treatment tank, a plurality of smashing cutters are fixedly installed on the outer side of the smashing shaft, and a fixing block is fixedly installed on the inner wall of the top of the treatment tank. Support bars are fixedly mounted between the bottom of the fixing block and the inner wall ofthe bottom of the treatment tank, each support bar is of a U-shaped structure, a same filter screen is movably connected between each pair of support bars, and a rectangular box is fixedly connected to the top of the treatment tank. A plurality of crushing shafts are arranged to drive the plurality of smashing cutters to crush residues in sewage, the sewage is filtered through the filter screens,and the filtering degree of the sewage can be improved by crushing the residues in the sewage; the aerated grit chamber is convenient to operate, impurities in sewage in the treatment tank can be crushed and filtered, the aeration effect is improved, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aeration grit chamber for sewage treatment. Background technique [0002] The aerated grit chamber is a long channel with a sand collecting bucket at its lower part. The bottom of the tank has a slope to ensure that the sand particles slide in. Due to the aeration, the organic particles in the wastewater are often in a suspended state, and the sand particles rub against each other and bear The shear force of aeration can remove the organic matter attached to the sand particles, which is beneficial to obtain relatively pure sand particles. Under the action of the centrifugal force of the swirling flow, these denser sand particles are thrown to the sand collection chamber, while the less dense organic matter It flows forward with the water flow and is taken to the next processing unit. [0003] The existing grit chamber cannot crush and filter the impurities in the sew...
