Description

Technical Field

[0001] The utility model relates to the technical field of grit chambers, in particular to a grit chamber sand processing structure. Background Art

[0002] A grit chamber is a structure for removing heavier sediments such as gravel, coal dust, and fruit cores from sewage. It is located behind the grilles and screens of the sewage treatment plant and in front of the sedimentation tank. There is not much sediment in pure domestic sewage, but after mixing with water for washing the ground and rain and snow water, the sewage contains a high amount of sand, so a grit chamber should generally be set up. Sewage from a combined sewer system should be equipped with this equipment to ensure the normal progress of subsequent treatment. The gravel removed from the grit chamber is used for filling or burial after drying. If it is mixed with organic suspended matter, it must be treated harmlessly to avoid corruption and odor, which will attract flies. The water discharged during the drying process of the gravel should be diverted to the inlet of the sewage treatment plant for further treatment.

[0003] However, in the currently used grit chambers, a large amount of rainfall falls into the grit chambers during the summer and other seasons with heavy rainfall, causing the water in the grit chambers to overflow and be discharged outward. The overflowing water easily carries mud and sand around the grit chambers, which may cause pollution to the surrounding areas. In addition, it is very troublesome to clean up after the rain, wasting a lot of manpower.

[0004] Therefore, a sand treatment structure for a grit chamber is needed that can prevent the water from carrying silt over the grit chamber when the rainfall is heavy, facilitate subsequent cleaning, and save labor costs. Utility Model Content
