Abstract
The utility model discloses an integrated settling tank used in cleaning treatment process of municipal sewage, which comprises a tank body and a concentrator. The bottom of the tank is provided with a mud deposition area; the bottom of the tank body is inclined towards the mud deposition area. Mud pipes are arranged in the mud deposition area. The side wall of the inlet end of the tank body is provided with a sand settlement area; the bottom of the sand settlement area is provided with sand discharge pipes. The utility model is integrated with the functions of a sand settlement tank, deposition and chemical dosing; and has the functions and effects of a plurality of tanks. The utility model has the advantages of small floor space, and reducing dissipation of energy and work investment, and is widely applicable for cleaning treatment works of municipal sewage.
Description
Affiliated technical field
The utility model relates to a kind of urban sewage purification treating apparatus, in particular for the integrated sedimentation basin of impurity and suspension in the removal sewage.
Background technology
At present, in China's urban sewage treatment process, independently setting pot and sedimentation basin will be set all generally, setting pot is used for removing the sand and the bigger impurity of proportion of sewage, and sedimentation basin is used for separating the more tiny suspension of sewage.The dispensing of sewage purifies the general mode of ad hoc dispensing pond or pipeline dispensing that adopts and carries out.Not only floor space is big to adopt this independent setting mode, but also has increased energy consumption and construction investment, and the cost of sewage disposal is increased.
Summary of the invention
In order to overcome in the existing urban sewage treatment process, the floor space that independent setting setting pot and sedimentation basin bring is big, energy consumption and the big deficiency of construction investment, the utility model provides a kind of function that has setting pot and sedimentation basin simultaneously, and floor space is little, energy consumption and the little integrated sedimentation basin of construction investment.
The technical scheme that its technical problem that solves the utility model adopts is: this integrated sedimentation basin comprises pond body and thickener, the bottom of pond body is provided with mud accumulation area, the bottom of pond body tilts to mud accumulation area, be provided with discharge pipeline in the mud accumulation area, the water intake end sidewall of pond body is provided with the sand setting district, and the bottom in sand setting district is provided with the sediment outflow pipe.
The beneficial effects of the utility model are: integrate the function of setting pot, precipitation and dispensing, the effect and the effect in many ponds played in a pond, and floor space is little, reduced energy consumption and construction investment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cutaway view of the utility model structure.
The specific embodiment
Embodiment 1: as shown in Figure 1, integrated sedimentation basin of the present utility model comprises pond body 1 and thickener 2, the bottom 3 of pond body 1 is provided with mud accumulation area 4, be provided with discharge pipeline 5 in the mud accumulation area 4, the bottom 3 of pond body 1 tilts to mud accumulation area 4, is beneficial to mud at the bottom of the pond and enters mud accumulation area 4 smoothly and discharge from discharge pipeline 5.Also be provided with sand setting district 7 on the water intake end sidewall 6 of pond body 1, the bottom 8 in sand setting district 7 is provided with sediment outflow pipe 9.Sand setting district 7 is arranged on the outside of water intake end sidewall 6.The bottom 8 in sand setting district 7 tilts to sediment outflow pipe 9, is beneficial to sediment outflow.Also be provided with aeration perforated pipe 10 in the sand setting district 7.Municipal sewage enters sand setting district 7, by aeration the organic matter attached to sand grain surface is come off, and sand grains is deposited on the bottom 8 in sand setting district 7, with its separation; Oil is floating to the water surface with scum silica frost, can be discharged by additional oil-collecting, skimmer device.To taking off N, when specific (special) requirements being arranged, can adding assistant medicament, make sand setting district 7 possess the function in dispensing pond in sand setting district 7 except that P.Sewage after sand setting district 7 handles enters pond body 1 and precipitates.The middle part of pond body 1 is provided with water distribution wall 11 by a side in sand setting district, and the top between water distribution wall 11 and the water side sidewall 12 also is provided with inclined tube 13, makes the fluidised form of water become laminar flow by turbulent flow, in order to improve sedimentation effect.Precipitating sludge concentrates in this district and discharges from discharge pipeline 5, and its solid content can reach 3%.
If the sewage treatment process after the integrated sedimentation basin enters integrated sedimentation basin sand setting district 7 for carrying out a biological disposal upon and introducing a small amount of residual active sludge, carry out aeration.Because the activated sludge tool is necessarily active, fine suspension (SS) and part colloidal substance form the easily larger particles of precipitation in the absorption sewage, have further improved the sedimentation effect of integrated sedimentation basin.
In sum, through integrated sedimentation basin, the SS clearance can reach 70% in the sewage, BOD
5Clearance can reach 30%.
