Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment supporting facility for efficient and intensive sewage treatment stations in villages and towns. Background Art

[0002] Integrated sewage treatment plants are primarily used to treat domestic sewage from villages and towns. They are typically located downstream of villages and towns in low-lying areas. Traditional sewage treatment plants often include decentralized sewage treatment structures such as coarse screens, sludge tanks, and regulating tanks, which occupy a large area and require high project investment. With the development of villages and towns, national requirements for the conservation and intensive use of construction land, and environmental protection, higher requirements are being placed on the construction and operation of sewage treatment plants. The construction, expansion, renovation, and operation of sewage treatment plants often face the problem of limited construction land. Furthermore, sewage from villages and towns generally has a low water temperature. In winter, the water temperature is too low to ensure effective biological treatment. These issues require urgent solutions. Utility Model Content

[0003] The purpose of the utility model is to provide an efficient and intensive sewage treatment supporting facility for village and town sewage treatment stations, so as to solve the problem that sewage treatment buildings in traditional sewage treatment stations are scattered and occupy a large area.

[0004] The technical solution of the utility model is: a sewage treatment supporting facility for efficient and intensive village sewage treatment stations, comprising a grille well, a grit chamber and a regulating tank, as well as a disinfection tank and a sludge tank connected in sequence, the grille well and the grit chamber are arranged side by side on one side of the regulating tank, and the disinfection tank and the sludge tank are arranged side by side on the other side of the regulating tank; the grille well is connected to a water inlet pipe, the regulating tank is connected to the biological tank through an anoxic tank inlet pipe, the disinfection tank is connected to the biological tank through an aerobic tank outlet pipe, the disinfection tank is connected to a drain pipe, the sludge tank is connected to the biological tank through an aerobic tank sludge discharge pipe, and the sludge tank is connected to a sludge tank sludge discharge pipe.

[0005] As a further improvement of the present invention, the grille well is connected to the sand settling tank through a water hole.

[0006] As a further improvement of the present invention, the grit chamber is connected to the regulating tank through a water pipe.

[0007] As a further improvement of the present invention, the sewage treatment supporting facilities are arranged underground, and an insulation layer is provided on the peripheral pool wall of the sewage treatment supporting facilities.

[0008] The beneficial effects of this utility model include: it integrates the dispersed grate tank, grit chamber, regulating tank, sludge tank, and disinfection tank within a traditional sewage treatment plant into a single design, resulting in a compact and rational structural layout and reduced piping, thereby saving space and reducing project investment. The utility model buries the entire sewage treatment facility underground and provides an insulation layer on the outer tank walls to prevent low water temperatures in winter from affecting the treatment efficiency of the biological pool. This utility model is suitable for the construction, expansion, and renovation of sewage treatment facilities in rural and town sewage treatment plants, and can be widely promoted and applied, demonstrating its high practicality.

DETAILED DESCRIPTION

[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, a sewage treatment supporting facility for efficient and intensive village sewage treatment stations includes a screen well 1, a grit chamber 2 and a regulating tank 3, as well as a disinfection tank 4 and a sludge tank 5 connected in sequence. The screen well 1 and the grit chamber 2 are arranged side by side on one side of the regulating tank 3, and the disinfection tank 4 and the sludge tank 5 are arranged side by side on the other side of the regulating tank 3; the screen well 1 is connected to a water inlet pipe 9, the regulating tank 3 is connected to the biological tank through an anoxic tank inlet pipe 6, the disinfection tank 4 is connected to the biological tank through an aerobic tank outlet pipe 7, the disinfection tank 4 is connected to a drain pipe 10, the sludge tank 5 is connected to the biological tank through an aerobic tank sludge discharge pipe 8, and the sludge tank 5 is connected to a sludge tank sludge discharge pipe 11.

[0017] The grid well 1 is connected to the grit chamber 2 through a water hole 12. The grit chamber 2 is connected to the regulating tank 3 through a water pipe 13.

[0018] The sewage treatment supporting facilities are set up underground, and the outer pool wall of the sewage treatment supporting facilities is provided with an insulation layer.

[0019] The grille in the grille well 1 is a flat grille.

[0020] Sewage enters the screen well 1 from the water inlet pipe 9. The screen intercepts and removes larger suspended solids and paper scraps in the sewage, protecting the water pump and subsequent piping system from blockage. The sewage then enters the grit chamber 2 through the water hole 12, where the inorganic sand particles are precipitated. The sewage continues to enter the regulating tank 3 through the water pipe 13, which can fully balance the water quality and water quantity, allowing the sewage to enter the subsequent treatment units more evenly, improving the impact resistance of the entire system, reducing the design scale of the treatment units, and helping to reduce operating costs and the impact of water quality fluctuations. The water in the regulating tank 3 enters the biological tank through the anoxic tank inlet pipe 6. After undergoing a series of anoxic and aerobic treatments, it enters the disinfection tank 4 through the aerobic tank outlet pipe 7 for disinfection treatment, and is then discharged or reused through the drain pipe 10. At the same time, the sludge generated by the biological treatment of sewage in the biological tank is discharged into the sludge tank 5 through the aerobic tank sludge discharge pipe 8, and then discharged to the concentration tank through the sludge tank sludge discharge pipe 11 for treatment.

[0021] This new system solves various practical problems caused by limited construction land and low winter water temperatures during the construction (including new construction, expansion, and renovation) of rural sewage treatment stations. While conserving and intensively utilizing land, it also reduces project investment and prevents excessively low winter sewage temperatures, ensuring sewage treatment quality and facilitating subsequent operation, maintenance, and inspection.
