Background
At present, sewage ponds are arranged at chemical devices, storage and transportation tank areas or loading and unloading platform platforms of factories and are mainly used for collecting waste water mixtures such as waste water, oily sewage and the like generated in the production process, and when water and oil are mixed together, the waste oil can float on the upper layer of the waste water due to the light weight of the oil.
The existing sewage treatment technology is to extend an inlet pipeline of a sewage lifting pump to the bottom of a sewage pool directly to extract sewage, and to convey the sewage to a sewage treatment system by using a sewage pump. However, since the inlet pipeline of the sewage lift pump directly extends to the bottom of the sewage tank, as the sewage is gradually pumped out, the waste oil cannot be discharged to the sewage treatment system through the sewage lift pump when only the waste oil is left at the bottom of the sewage tank.
Therefore, the sewage treatment technology has the following disadvantages: firstly, the lift pump is likely to be evacuated due to light oil mass, so that the lift pump idles, and the service life of the lift pump is influenced; secondly, the residual floating oil in the sewage tank is enriched to generate a heavy peculiar smell, so that the environment is polluted, and even more, when the floating oil is enriched too much, an explosive mixture can be formed, so that certain potential danger exists for the personal safety of operating personnel; and thirdly, a matched filtering device is not arranged at the inlet of the sewage lifting pump or at the bottom of the inlet pipeline, when some large-particle massive wastes in the waste liquid pass through the inlet pipeline of the lifting pump, the inlet pipeline or the inlet of the lifting pump is blocked, so that the waste liquid cannot be effectively conveyed to a sewage treatment system by the lifting pump.
