Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment, and in particular relates to a solid waste treatment system in mixed sewage. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. The wastewater treatment process usually includes the removal of suspended matter, silt, grease and other impurities to avoid affecting subsequent treatment links. Common pretreatment methods include natural sedimentation, coagulation sedimentation, filtration, etc. Sewage is precipitated in a sedimentation tank and transported to the spray area for discharge via a vertical pipe sewage pump.

[0003] Chinese utility model patent CN210736381U discloses a sewage treatment device based on the restoration of the urban water network ecosystem, which relates to the field of sewage treatment technology, including a box and a filter device, wherein the filter device is located inside the box, and a water inlet is fixedly installed on the top of the box. In this sewage treatment device based on the restoration of the urban water network ecosystem, when it is necessary to filter and discharge solid waste in the sewage, the drive located on the back of the drum drives the two drums to rotate, and at the same time the first motor drives the turntable to rotate, and the protrusion on one side of the turntable drives the baffle to fit with one side of the second slot through the connecting rope, and the baffle located on one side of the two drums blocks the solid objects in the sewage, and the liquid water in the sewage passes through the through hole in the baffle into the water pipe, and the drum drives the baffle to rotate and moves the solid waste and drops it into the inclined opening;

[0004] The above design can screen out the solid waste inside the wastewater separately through the cooperation of multiple groups of components, which speeds up the overall screening speed and prevents the blockage of the pipeline. However, when treating mixed sewage, the sewage is not treated separately, resulting in the sewage being concentrated in a single group of sedimentation tanks, which is prone to blockage of the side pipelines of the sedimentation tanks, causing excessive pressure in the delivery pipeline and shortening the service life of the components themselves.
