Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a pipeline structure for sewage treatment. Background Art

[0002] Sewage treatment aims to remove harmful substances in sewage, including industrial sewage treatment and rain sewage treatment. The above two types of sewage treatment are for the wastewater from industrial production processes and the rain sewage generated when rainwater may mix with various pollutants when flowing over the ground during rainfall. Sewage treatment is to remove the pollutants in it to meet the standards for safe discharge into the environment. According to different treatment methods, sewage treatment can be divided into physical treatment methods, chemical treatment methods, biological treatment methods, and physicochemical treatment methods.

[0003] Among the above treatment methods, the physical treatment method is the most widely used method in existing sewage treatment. Usually, screening (such as using a grille to remove large particles), sedimentation (such as using a grit chamber to remove heavier particles), flotation (to remove light suspended solids), filtration (such as using a sand filter to remove fine particles), etc. are used. These methods are mainly used to remove impurities such as suspended substances, sediment, and floating oil in sewage.

[0004] The existing Chinese patent with the reference publication number CN215275954U discloses a rain sewage treatment pipeline, which is applied in the field of rain sewage treatment and solves the technical problem that when the treatment volume of rain sewage is large, it will cause a large discharge pressure on the rain sewage treatment pipe. The key points of its technical solution are a rain sewage treatment pipeline, including a buffer well. The side wall of the buffer well is connected to a drain pipe. A filter cylinder is arranged in the buffer well. There is a gap between the upper end of the filter cylinder and the manhole cover. The inner wall of the buffer well at the gap is connected to a sewage inlet pipe. The filter cylinder is provided with a number of filter holes. The upper end of the buffer well is provided with a manhole cover, and the manhole cover is provided with a number of water seepage holes. The technical effect is to slow down the discharge pressure of the drain pipe.

[0005] Although this patent has the effect of reducing the buffer pressure of rainwater, when it is in use, since rainwater is easy to carry garbage into the filter cylinder from the gap of the manhole cover, when the rainfall is large, the garbage will block the filter cylinder, and then it is extremely easy to occur that the filter cylinder is blocked during the use of this treatment pipeline, affecting the specific use. Therefore, the inventor has proposed a pipeline structure for sewage treatment to solve the above-mentioned technical problems. Summary of the Utility Model
