Abstract
The invention relates to a radial flow sedimentation tank into which peripheral water flows and out of which water is drained continuously. The sedimentation tank is characterized in that: the tank body is cylindrical and the lower part is a conical sludge district; by the adoption of the way of water flowing into the tank from periphery, a plurality of water holes for supplying the water to flow into the tank are arranged on a inlet groove; the outlet adopts a cruciform outlet groove for water drainage arranged long the radial direction; outlet weirs are arranged at the two sides of the outlet groove and an adjustable baffle is arranged in the outlet groove; the rate of water flow and the outlet positions of the outlet weirs can be adjusted by regulating the length of the outlet weirs so as to adapt to the change of water flow to keep a best route for the sedimentation of particle substances to enhance the outlet water quality. The adjustable outlet groove which can drain water continuously increases the outlet area to reduce the outlet flow speed, and maintains even distribution of outlet water and the best outlet position; therefore the sedimentation load is increased, the efficiency is enhanced and the investment and floor area are reduced.
Description
Technical field
The present invention relates to the technical field of sedimentation basin, specifically a kind of radical sedimentation basin of periphery water-inlet continuous water-outlet.
Technical background
Radical sedimentation basin is a kind of critical facility that slurries concentrate, and general sedimentation basin comprises intake tunnel, settling zone, mud district and exhalant canal.Existing radical sedimentation basin come to divide the three kinds of forms that mainly contain according to the Inlet and outlet water mode, i.e. three kinds of center water inlet peripheral effluent, the water outlet of circumferential water feed center and circumferential water feed peripheral effluents.Wherein center water inlet peripheral effluent radical sedimentation basin is used morely, and waste water is gone into the pond from center, pond water inlet pipe, along radial direction to pond Zhou Liudong, water velocity from fast to slow, suspension sedimentation in flowing, and enter sludge bucket along the pond bottom sloping, primary water is gone into out water channel from pond Zhou Yiliu.But this sedimentation basin is owing to concentrate the inlet area little, and causing sedimentation basin to turn over the pond easily under the unstable water velocity variation of inflow situation greatly is that bottom precipitation mud is taken up phenomenon again, and load is lower, and the time of staying is long, and the slurries concentrating efficiency is not high.
Water outlet radical sedimentation basin in circumferential water feed center improves in the district that becomes a mandarin, and intake chamber is positioned at one week of sedimentation basin, and section is bigger, and it is much smaller that waste water enters the flow velocity of settling zone, helps the precipitation of suspended particulate.And peripherally-distributed water makes the density current degree alleviate greatly, has improved the utilization rate in pond, and its surface loading can be than 1～2 times of the raising of center inlet type, and sedimentation effect is good, spoil disposal concentration height.The effluent trough region area in pond is little, and the effluent weir duty ratio is higher, goes out the water flow velocity height, and is bigger to the effluent quality influence.
Precipitation pool with peripheral, its structure are along periphery distribution channel and rhone to be set.Distribution channel links to each other with water inlet pipe in the outside, and rhone links to each other with outlet pipe in the inboard, is provided with sparge pipe at the bottom of the distribution channel.This sedimentation basin easily causes short circuit phenomenon when inflow changes, make sedimentation effect relatively poor.
Summary of the invention
In order to overcome prior art in the deficiency of handling in water inlet and the water outlet, the invention provides a kind of radical sedimentation basin to the efficient a kind of periphery water-inlet continuous water-outlet that concentrates of slurry mixture, adopt the periphery water-inlet continuous water-outlet mode, it is characterized in that water-out manners is between peripheral effluent and center water outlet, water inlet pipe is communicated with sedimentation basin circumferential water feed cloth tank, circumferential water feed cloth bottom of gullet is provided with the water distributing pore that a plurality of water supply flow into the pond, the cross continuous effluent groove draining that effluent adopting is disposed radially, these four continuous effluent grooves are concentricity, and collector pipe is communicated with, and in cross continuous effluent groove, adjustable baffle plate is set, adjust the length of mill weir, the water-outlet area that increased this adjustable continuous effluent groove has reduced and water flow velocity, kept water outlet evenly to distribute and best water outlet position, the precipitation load increases, efficient improves, and investment and floor space reduce.
The present invention adopts the circumferential water feed mode, compare with above-mentioned radial-flow sedimentation tank, its load is big, because circumferential water feed water distribution channel section is bigger, and the aperture of bottom land is less, and the loss of flood peak during water distribution concentrates on the aperture, and water distribution is even, and slurry mixture to enter the flow velocity of settling zone much smaller, help the precipitation of suspended particulate.Adopt the continuous effluent mode, that has avoided that issuable short circuit phenomenon of peripheral effluent mode and center go out water generates goes out the higher phenomenon that influences water quality of water flow velocity, this adjustable continuous effluent groove has increased water-outlet area, has reduced water flow velocity, obtains treatment effect preferably.In the continuous effluent groove adjustable baffle plate is set, adjusts water level according to the variation of the water yield and put, guarantee the optimal path of current precipitation and good sedimentation effect.
The radical sedimentation basin of this periphery water-inlet continuous water-outlet is when concentrating as slurry mixture, and the design sedimentation time is 1.0～2.0h, and hydraulic surface loading is 2.0～6.0m
