The specific embodiment
For being illustrated more clearly in content of the present invention, do further to describe below in conjunction with the accompanying drawing and the specific embodiment:
For vertical sedimentation basin, the motion of the particle in the water is mainly formed by gravity, buoyancy and hydrodynamic effect acting in conjunction, realize sedimentation; Gravity must be greater than buoyancy and hydrodynamic acting in conjunction, and promptly the solid separated decrease speed is greater than the current rate of climb, and solid just can avale; If water velocity is big more, the hydrodynamic effect that particle receives is just big more, and particle is difficult to sedimentation; Therefore need reduce water velocity as far as possible, be beneficial to the deposition of particle.
As shown in Figure 1, the water distribution manner of center stand column water inlet at the bottom of the existing vertical sedimentation basin employing pond, water volume flow rate V is synthetic by radial level component velocity V1 and rate of climb V2; And the flow velocity of diverse location point is all inconsistent, forms turbulent flow easily, is difficult to form stabilized zone in the water distribution zone of bottom; Need increase the pond body degree of depth for this reason; Form the stable region, thereby make hydrodynamic effect that particle receives and gravitational effect, make particle be easy to precipitate at collinear two rightabouts.If the pond is not enough deeply, very likely form single-point radiation gauze water inlet from the cloth water spot to delivery port, the particle in the sewage is difficult to deposition.Therefore, the overall depth of traditional vertical sedimentation basin reaches 4.5 meters, wherein rhone place layer h1 about 0.5 meter dark, water distribution zone h2 about 3 meters dark, mud-collecting slot and discharge pipeline place layer h3 about 1 meter dark.
