Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, and particularly relates to an underground integrated sewage treatment equipment. Background Technique

[0002] The underground integrated sewage treatment equipment is an efficient sewage treatment equipment, and its working principle mainly includes the following steps:

[0003] Pretreatment: Sewage first enters the grille, and larger suspended solids and impurities are removed through the filtering effect of the grille; then, the sewage enters the regulating tank, and the function of the regulating tank is to regulate the water volume and water quality of the sewage to meet the requirements of the subsequent treatment unit;

[0004] Biological treatment: The sewage in the regulating tank enters the biological treatment unit, and the biological treatment unit usually adopts the activated sludge method or the biofilm method; in the activated sludge method, the sewage is mixed with the activated sludge, and oxygen is supplied to the sewage through the aeration equipment, so that the microorganisms in the activated sludge can decompose the organic matter in the sewage; in the biofilm method, the sewage passes through the surface of the filler, and the microorganisms attach to the surface of the filler to form a biofilm, and the organic matter in the sewage is decomposed by the microorganisms in the biofilm;

[0005] Sedimentation: The sewage after biological treatment enters the sedimentation tank, and the function of the sedimentation tank is to precipitate the suspended solids and biofilm in the sewage, so as to realize the separation of mud and water; a part of the sedimented sludge is refluxed to the biological treatment unit, and the other part is discharged from the system for treatment;

[0006] Disinfection: The sewage after sedimentation enters the disinfection tank, and the function of the disinfection tank is to kill the bacteria and viruses in the sewage and ensure the safety of the effluent quality; disinfection usually adopts chemical disinfection methods, such as chlorine addition disinfection or ultraviolet disinfection, etc.;

[0007] Discharge: After the disinfected sewage reaches the national or local discharge standards, it can be discharged into natural water bodies or reused through the discharge pipeline;

[0008] The underground integrated sewage treatment equipment has the advantages of small floor area, high treatment efficiency, stable operation, etc., and is suitable for various sewage treatment occasions such as domestic sewage and industrial wastewater;

[0009] Taking the underground integrated sewage treatment with the model HY-YTH as an example, when the equipment is buried underground, the soil outside the equipment squeezes the side wall of the equipment, and the pressure of the soil may cause the shell of the equipment to deform, especially for some equipment with relatively thin materials or insufficient strength; the deformation of the equipment may affect the stability of the internal structure and further affect the normal operation of the equipment.
