Abstract
The utility model discloses a zhou jinzhou goes out two heavy ponds of spoke STREAMING, including setting up intake water distribution hole and the water conservancy diversion skirtboard in the inlet channel bottom, to sink on the inside wall in ponds two, the water distribution hole that intakes is equipped with the reflecting plate under, the distance of this reflecting plate and the water distribution hole bottom face of intaking is less than the height of water conservancy diversion skirtboard. The utility model discloses an increase the reflecting plate, rivers spread rapidly before getting into the sedimentation tank main part to very low speed gets into the settling section from being close to the bottom of the pool, in the time of avoiding the variation in discharge great high -speed intake with the short phenomenon that flows, reduce by two heavy ponds and intake to hold and float the mud phenomenon. But also possess the sludge settling of being favorable to layering, deposit efficient advantage.
Description
Technical field
The utility model belongs to sewage treatment facility field, is specifically related to a kind of Zhou Jinzhou and goes out Radial Flow Secondary Sedimentation Tank.
Background technology
For circumferential water feed peripheral effluent Radial Flow Secondary Sedimentation Tank, the uniformity of water distribution determines the quality of its sedimentation effect, its uniformity water distribution is realized by series of measures, such as: inlet channel adopts Varied section to keep the movement at the uniform velocity of channel water stream in actual application; Distributing hole opening's edge journey displacement, makes peripherally to be uniformly distributed into water; Water inlet water distribution aperture arranges water conservancy diversion skirtboard, controls water distributing area water velocity, eliminates the water inlet short stream of water distribution aperture periphery and whirling motion etc.
These measures no doubt can make the water distribution of second pond more even, but still there is following defect in prior art:
1. when changes in flow rate is larger, water inlet is with short flow phenomenon at a high speed, and water inlet end exists drift mud phenomenon.
2. circumferential water feed peripheral effluent Radial Flow Secondary Sedimentation Tank system Reynolds number of the prior art and Fu Laode criterion numeral higher.
3. mixed liquor can not enter into suspension flocbed fast, and deposition efficiency is on the low side.
Utility model content
For the problems referred to above, the utility model aims to provide one can avoid short flow phenomenon, and reduce water inlet end drift mud phenomenon, be conducive to sludge settling layering, the Zhou Jinzhou that deposition efficiency is high goes out Radial Flow Secondary Sedimentation Tank.
The technical scheme that the utility model is dealt with problems is: a kind of Zhou Jinzhou goes out Radial Flow Secondary Sedimentation Tank, comprise and be arranged on water inlet distributing hole bottom inlet channel and water conservancy diversion skirtboard, on the madial wall of second pond, immediately below water inlet distributing hole, be provided with reflecting plate, this reflecting plate is less than the height of water conservancy diversion skirtboard with the distance of water inlet distributing hole bottom surface.
Angle between the upper surface of described reflecting plate and horizontal line is 0 degree ~ 15 degree; Preferably, the upper surface of described reflecting plate and water inlet distributing hole axes normal.
Remarkable result of the present utility model is:
(1) by increasing reflecting plate, current spread rapidly before entering sedimentation basin main body, enter settling section, because flow velocity is very little with low-down speed near bottom, pond, when changes in flow rate can be avoided larger at a high speed water inlet with short flow phenomenon, reduce second pond water inlet end drift mud phenomenon.
(2) by increasing reflecting plate, Reynolds number and the Fu Laode criterion numeral of second pond system is reduced further.The little explanation effect of inertia of Reynolds number reduces relatively, and viscous force relativity increases; Fu Laode criterion numeral is less than 1, and current are in unhurried current.These all impel fluidised form in second pond to develop to laminar flow, are conducive to sludge settling layering.
(3) there is clarification water layer, suspension flocbed, the dense compression layer of mud and mud bottom flow layer four levels in second pond.By increasing reflecting plate, mixed liquor enters into suspension flocbed fast, the effects such as the activated sludge of the activated sludge particles in mixed liquor constantly and in superposed layer collides, adsorb, combine, flocculation, produce good suspending clarification effect, improve deposition efficiency further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the drawing of the utility model second pond into and out of water channel.
Fig. 2 is D-D profile in Fig. 1.
In figure: 1-inlet channel, 2-is intake distributing hole, 3-water conservancy diversion skirtboard, 4-reflecting plate.
Detailed description of the invention
As shown in Fig. 1 ~ 2, a kind of Zhou Jinzhou goes out Radial Flow Secondary Sedimentation Tank, comprise and be arranged on water inlet distributing hole 2 bottom inlet channel 1 and water conservancy diversion skirtboard 3, on the madial wall of second pond, immediately below water inlet distributing hole 2, be provided with reflecting plate 4, this reflecting plate 4 is less than the height of water conservancy diversion skirtboard 3 with the distance of water inlet distributing hole 2 bottom surface.
The upper surface of described reflecting plate 4 and the axes normal of water inlet distributing hole 2.
Claims (3)
1. one kind is entered week to go out Radial Flow Secondary Sedimentation Tank in week, comprise and be arranged on water inlet distributing hole bottom inlet channel and water conservancy diversion skirtboard, it is characterized in that: on the madial wall of second pond, immediately below water inlet distributing hole, be provided with reflecting plate, this reflecting plate is less than the height of water conservancy diversion skirtboard with the distance of water inlet distributing hole bottom surface.
2. Zhou Jinzhou according to claim 1 goes out Radial Flow Secondary Sedimentation Tank, it is characterized in that: the angle between the upper surface of described reflecting plate and horizontal line is 0 degree ~ 15 degree.
3. Zhou Jinzhou according to claim 1 and 2 goes out Radial Flow Secondary Sedimentation Tank, it is characterized in that: upper surface and the water inlet distributing hole axes normal of described reflecting plate.
