Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for automatically pumping sewage. Background Technique

[0002] After sewage is treated, the water quality is greatly reduced from the original polluted state through repeated filtration and elimination, enabling the water to be reused. By reasonably using water resources, the water cycle in the upstream area does not affect the water body function of the downstream water area, and the social cycle does not damage the objective law of the natural cycle, so as to maintain or restore the good water environment of the city and even the basin. This is the effective way for sustainable water resource utilization, improving the ecological environment, enhancing the urban grade and promoting economic development. Because if sewage is not treated, it will inevitably be discharged into the river, which will not only pollute the environment but also have an adverse impact on the quality of people's domestic water. The natural cycle of water is a non-equilibrium open system with self-organizational structure, and the social cycle of water is a balanced system with artificial organizational structure.
