Abstract
The invention discloses a kind of novel vertical sedimentation basins, by being allowed to form diversion trench in sedimentation basin taper sludge bucket surface layout deflector, are arranging porous water distribution disturbance pipe in diversion trench.The perturbation action of pipe is disturbed by porous water distribution, strengthens the mobility for being deposited on taper sludge bucket surface sludge, sludge is made preferably to be slipped to taper sludge bucket bottom.It is good that novel vertical sedimentation basin structure of the invention is simple, easy to implement, sedimentation basin does not collect mud, sludge discharge effects.
Description
Technical field
The invention belongs to wastewater treatment settlers, and in particular to a kind of novel vertical sedimentation basin.
Background technique
In technical field of waste water processing, vertical sedimentation basin is mainly used for being separated by solid-liquid separation.For example, coagulation process water outlet is heavy
Shallow lake separation, precipitation and separation of biochemical process water outlet etc..The sludge of vertical sedimentation basin is the taper sludge by precipitating bottom of pond portion
Bucket collects the sludge that settling zone precipitates, finally, the sludge pipe by bottom drains sludge.The angle one of taper sludge bucket
As at 50 ° -55 °.But in actual application kind, since sludge specific gravity and water are very close to mobility in water is opposite
It is poor.Even if taper sludge bucket is at 50 ° -55 °, sludge also cannot rely on gravity often and be slipped to taper sludge bucket bottom,
Sedimentation basin cannot be discharged in sludge in time in this way.For a large amount of sludge retentions on taper sludge bucket surface, the time is long, these dirts being detained
Mud generates gas or since gases, these gases such as anaerobism generation hydrogen sulfide, methane can be held in the palm since anti-nitration reaction occurs for anoxic
Floating Mud up-floating forms a large amount of drosses in precipitating pool surface, influences the separating effect of sedimentation basin.It is asked currently in order to solving this
Topic, is commonly installed mud scraper, by sludge scraping to taper sludge bucket bottom.But installation mud scraper, making sedimentation basin, structure is complicated,
Due to needing to work in water, also there is higher requirement to mud scraper structure member.It will increase the construction cost of sedimentation basin, simultaneously
From the point of view of current practical experience, it is mounted with mud scraper, sludge discharge effects are also not highly desirable.
Summary of the invention
The technical scheme is that：A kind of novel vertical sedimentation basin, characterized in that it includes sedimentation tank body, water inlet
Pipe, central tube, sludge pipe, effluent weir, taper sludge area, mud collection area.It is described to be allowed in taper sludge area surface layout deflector
Diversion trench is formed, arranges that porous water distribution disturbance pipe, porous water distribution disturbance pipe connection water distribution ring pipe, water distribution are vertical in diversion trench
Pipe, and disturbed and managed for applying pressure water to porous water distribution by water distribution vertical tube.
The outlet water orifice diameter of the porous water distribution disturbance pipe is 5-10mm, flow velocity is greater than 1m/s, interval 200-250mm obliquely
45 DEG C of arrangements.
The height of the deflector is 100-150mm；The width of diversion trench is 250-350mm.
A kind of Novel vertical flow type sedimentation structure of the invention is simple, easy to implement, sludge discharge effects are good, and its is low in cost.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, waste water is entered the central tube 10 of sedimentation basin by water inlet pipe 8, by water after central tube 10 to enterprising
Entering settling zone, during flowing up, water is to upstream, and mud precipitates downwards, and final clarification water is discharged by effluent weir 7,
And mud precipitates drop to 11 surface of taper sludge bucket downwards.In the diversion trench that taper sludge bucket surface layout has deflector 2 to be formed
12.After a large amount of sludge has been gathered due to precipitating in taper sludge bucket surface 11, pressure water passes through water distribution vertical tube 4, cloth water ring
Shape pipe 3 finally enters porous water distribution disturbance pipe 1, by the water outlet perturbation action of porous water distribution disturbance pipe 1, to increase sludge
Mobility, later sludge can swimmingly along diversion trench 12 flow into sedimentation basin mud collection area 5, finally by 6 row of sludge pipe
Out.The final sludge for realizing that sedimentation basin precipitates is slipped to sedimentation basin mud collection area in time and is discharged, without causing sludge retention
On taper sludge bucket surface, it also would not go out water surface in sedimentation basin and form dross.
