Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a solid-liquid pre-separation device for sewage treatment in environmental protection projects. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the required water quality for discharge into a water body or reuse. Wastewater treatment is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life.

[0003] The prior art patent with announcement number CN221309787U discloses a solid-liquid pre-separation device for sewage treatment in environmental protection projects, comprising a base body (1) in a frame structure, a power assembly (2) and a transmission assembly (3) mounted on the base body (1), and the collected solid suspended matter is transported to a garbage net (4) at the rear via the power assembly (2) and the transmission assembly (3). The utility model is used in sewage treatment in environmental protection projects, and can pre-treat the solid-liquid mixture floating on the sewage surface, collect the solid suspended matter on the sewage surface via a solid suspended matter collecting fan (206) onto the transmission assembly (3), and the sewage leaks into the sewage pool through a water leakage hole (302). The utility model has the transmission assembly (3), and can achieve continuous solid-liquid separation, reducing manual labor.

[0004] When this patent treats floating solids on the surface of sewage, the accumulation of solid floating matter on the transmission component can easily clog the leakage holes, thereby affecting the outflow of water. In addition, this patent can only pre-treat the solid-liquid mixture floating on the surface of sewage. The smaller solid particles in the sewage will flow to the next process through the pores of the garbage net, which will increase the workload of the next process and reduce the sewage treatment efficiency. Therefore, a solid-liquid pre-separation device for sewage treatment in environmental protection projects is needed. Utility Model Content
