Abstract
The utility model relates to a sewage treatment device, in particular to a vertical sedimentation basin, which aims to solve the technical problems that the existing device has unreasonable structure and poor sewage treatment effect, and includes an anoxic basin, an aeration basin, a sedimentation basin and a clear liquid collecting basin, wherein the upper end of the aeration basin is connected with the sedimentation basin through an intermediate water inlet pipe; the water outlet of the intermediate water inlet pipe is connected with a perforated water distributing pipe; the sewage is uniformly distributed in the sedimentation basin through the perforated water distributing pipe; the upper clear liquid in the sedimentation basin enters the clear liquid collecting basin through an overflow channel; and a part of the sludge in the sludge bucket at the lower end of the sedimentation basin is pumped into the aeration basin through a perforated sludge discharge pipe, and the remaining part of the sludge is discharged outside. By arranging the perforated water distributing pipe and the perforated sludge discharge pipe in the sedimentation basin, not only the sewage can be uniformly distributed in the sedimentation basin, but also the sedimented sludge can be quickly and completely treated. The vertical sedimentation basin with the structure breaks the limit of the shape design, can be flexibly treated, and has a wider application range.
Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly relates to a kind of vertical sedimentation basin that is used for WWT.
Background technology
Present common vertical sedimentation basin generally is meant the vertical mobile settling tank of waste water in the pond.Pond body plane figure is circular or square; Water gets in the pond (in the pipe flow velocity should less than 30mm/s) from top to bottom by the water inlet pipe that is located at the center, pond; Pipe is divided into umbrella-shaped baffle makes waste water in the pond, slowly rise and (be generally 0.5-0.7mm/s for sewage along whole water-carrying section behind the uniform distribution; ST is adopted 1-1.5h), suspended substance sedimentation gets in the heavy bucket of pond base cone shape, and primary water goes out along the peripheral overflow weir flow from the pond all around.Baffled and scum silica frost groove guarantees effluent quality to hold back scum silica frost before the weir.The one side in pond is established shore pipe (diameter is greater than 200mm) by pool wall and is leaned on hydrostaticpressure that mud is regularly discharged.
The shortcoming of common vertical sedimentation basin:
1. treatment effect receives the influence of influent quality to produce bigger fluctuation easily;
2. water inlet pipe only is applicable to square or circular pond body, causes easily for rectangle pond body that into water is inhomogeneous.
The utility model content
The purpose of the utility model is to solve existing common vertical sedimentation basin structure to be provided with unreasonable and to handle the technical problem of water yield effect shortcoming when big; A kind of vertical sedimentation basin is provided, and this settling tank is through the setting of perforation water distributor and perforated sludge discharge pipe, makes sewage can not only water distribution in settling tank even; And the sedimentary mud of eliminating that can be quick and complete; This structure setting no longer is restricted the shaped design of settling tank, can handle flexibly according to practical situation, is suitable for more extensive.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of vertical sedimentation basin, comprise anoxic pond, aeration tank, settling tank and clear liquid collecting tank, and wherein anoxic pond is used to make the sewage anoxic to carry out denitrification to enter the aeration tank then; The aeration tank is used for the organism nutritive substance of degradation of sewage; The upper end, aeration tank is connected to settling tank through middle water inlet pipe, and sewage is drained in the settling tank through middle water inlet pipe, and the settling tank upper end is provided with overflow groove; Supernatant in the settling tank enters into the clear liquid collecting tank through overflow groove, and the settling tank lower end is provided with the bucket that is used to collect mud.
In technique scheme; The water outlet place of water inlet pipe is connected with the perforation water distributor in the middle of said; The perforation water distributor is horizontally disposed with, and the sewage of discharging from middle water inlet pipe is distributed in the settling tank bottom uniformly through the perforation water distributor, and the below of perforation water distributor is provided with the perforated sludge discharge pipe of arrangement in parallel; Perforated sludge discharge pipe middle part is connected with sludge reflux pump in the aeration tank through pipeline, and the mud part in the bucket is pumped in the aeration tank through perforated sludge discharge pipe.
In technique scheme, the central point of said perforation water distributor is connected with middle water inlet pipe, offers perforation from central point respectively toward two ends; The perforation that decentering point is far away more, the distance between the perforation is short more, and the central point of perforated sludge discharge pipe is connected with sludge reflux pump in the aeration tank through pipeline; Also offer perforation from central point respectively toward two ends; The perforation that decentering point is far away more, the distance between the perforation is short more, and the perforation on the perforated sludge discharge pipe Open Side Down is provided with.
Can find out that from each item technical characterictic of above-mentioned the utility model its advantage is: through the test of perforation water distributor perforation, confirmed the punch position of perforation water distributor, can solve the uniform problem of different shape pond body water distribution; Through the test of perforated sludge discharge pipe perforation, confirmed the punch position of perforated sludge discharge pipe, can in time take the mud that the settling tank bottom accumulates away, there is not the dead band, can fine mud scum problem of separating settling tank.This settling tank is through the setting of perforation water distributor and perforated sludge discharge pipe; Make sewage can not only water distribution in settling tank even; And the sedimentary mud of processing that can be quick and complete; This structure setting no longer is restricted the shaped design of settling tank, can handle flexibly according to practical situation, is suitable for more extensive.

Embodiment
Through embodiment the utility model is done further explanation below in conjunction with accompanying drawing.
Preferred embodiment
A kind of vertical sedimentation basin as depicted in figs. 1 and 2, its working process is: the former water of sewage is introduced into anoxic pond, participates in denitrification in anoxic pond; Get into the aeration tank then, in the aeration tank, decompose the organism nutritive substance in the waste water under the action of microorganisms, water inlet pipe in the middle of mud mixture flows into through upflow tube; And entering perforation water distributor; The perforation water distributor is evenly distributed in the settling tank bottom with water, forms to the upper reaches, in the process at upper reaches; Realize mud-water separation in the mud-water separation district, supernatant gets into overflow groove and flows into the clear liquid collecting tank.A precipitating sludge part is evacuated to the aeration tank as returned sluge by perforated sludge discharge pipe by the sludge reflux pump pump, and part effluxes as excess sludge.Settled active sludge is collected in the settling tank bucket, and logical residual sea water pump is evenly discharged from perforated sludge discharge pipe.
