Technical Field

[0001] The utility model relates to the technical field of sewage lifting pumps, in particular to an integrated sewage lifting pump station. Background Art

[0002] An integrated sewage pumping station refers to a sewage treatment facility that integrates various functional components such as sewage pumps, pipes, valves, and control equipment into one device or one structural system. It usually includes pumps, sewage collection wells, valves, pipes, electrical control equipment, and possible additional equipment such as sewage treatment units or monitoring systems. This design makes the installation and maintenance of sewage pumping stations easier, while saving space and construction costs. Sewage pumping stations are mainly used to flow sewage from low places to high places for treatment or discharge. They are usually used in urban sewage treatment systems to help sewage flow and treatment smoothly, and maintain environmental hygiene and public health.
