Physical sewage treatment system used for sewage treatment from source

Abstract

The invention discloses a physical sewage treatment system used for sewage treatment from the source, comprising a solid-liquid separation device and a settling device. The solid-liquid separation device is provided with a solid-liquid separator, and a separation water inlet, a separation water outlet and a separation sewage discharging port of the solid-liquid separator; the settling device comprises a settling shell the bottom of which is provided with a settling sewage discharging port, a water inlet hose and a water outlet hose are arranged in the settling shell, the water inlet end of the water inlet hose is connected with the separation water outlet of the solid-liquid separation device, the water outlet end of the water inlet hose is connected with a hollow floating disk, the outline of the floating disk adapts to that of the cross section of the settling shell, and a plurality of through holes are uniformly distributed in the annular area of the bottom surface, close to the edge; a floating disk water outlet is arranged on the bottom of the floating disk and is connected with the water inlet end of the water outlet hose, and the water outlet end of the water outlet hose extends out of the settling shell. The sewage treatment system can be used for treating sewage timely from the pollution sources, thus reducing or avoiding the phenomenon that sewage enters public water body.

Description

technical field [0001] The invention relates to a sewage and sewage treatment system, in particular to a physical sewage and sewage treatment system which can be used for source pollution control. Background technique [0002] At present, some production and domestic sewage are directly discharged, which not only wastes water resources, but also affects the natural environment; some are discharged after being treated by setting up sewage treatment plants. As for the treatment of industrial and civil sewage, a traditional physical treatment method is to complete the whole process of sewage treatment by passing the discharged sewage through sedimentation tanks, advection tanks, filtration devices, concentration tanks, and mud-water separation devices. The problems of such a treatment process are: the equipment used occupies a large area, the sewage interception pipeline is long, the construction cost is high, the equipment investment is huge, the operating cost is high, and th...

AI Technical Summary

Problems solved by technology

The problems of such a treatment process are: the equipment used occupies a large area, the sewage interception pipeline is long, the construction cost is high, the equipment investment is huge, the operating cost is high, and the land acquisition and demolition are difficult. It is difficult to adopt for a small and medium-sized enterprise and a residential area This method is used for sewage treatment, and the popularization and application of this high-input, high-operating-cost treatment process has certain limitations.

[0005] In addition, due to the fact that the available fresh water on the earth is relatively small compared to the increasing water demand of our human beings, coupled with the uneven distribution of fresh water resources and increasingly serious water pollution, the available fresh water is further reduced , resulting in a severe shortage of water resources available globally
