Description
技术领域technical field
本发明属于水处理技术领域，具体涉及一种将异向流斜管或斜板组件和水平流斜板组件组合使用的水处理装置。The invention belongs to the technical field of water treatment, and in particular relates to a water treatment device which combines a different direction flow inclined pipe or an inclined plate assembly and a horizontal flow inclined plate assembly.
背景技术Background technique
浅池理论提出以后，异向流斜管或斜板沉淀池因其沉淀效率高、占地面积小、工程造价低等优点，在全国各地的水厂中被广泛使用。但在运行过程中发现异向流斜管或斜板沉淀池还存在着以下几方面的问题：一、异向流斜管或斜板沉淀池的进水方向与水流流动方向相垂直，这样会使水流在由配水区进入斜管或斜板内部时产生剧烈的扰动，会将由斜管或斜板区沉降下来的絮体打碎，不利于絮体颗粒的沉降；二、配水区所占空间较大，水流由沉淀池一侧进入配水区，沿池长方向配水不均匀；三、配水区和泥斗之间没有阻隔，进入配水区的水流由于重力流的影响向下扰动，可能会将泥斗内的絮体搅起，不利于絮体的沉降。上述几个问题的存在限制了沉淀池沉淀效率的进一步提高，并在一定程度上使其对水质水量的变化适应能力较差。After the shallow pool theory was put forward, counterflow inclined tubes or inclined plate sedimentation tanks have been widely used in water plants all over the country because of their high sedimentation efficiency, small footprint, and low engineering cost. However, in the course of operation, it is found that the counterflow inclined tube or inclined plate sedimentation tank still has the following problems: 1. The water inlet direction of the counterflow inclined tube or inclined plate sedimentation tank is perpendicular to the direction of water flow, which will cause When the water flow enters the inclined tube or inclined plate from the water distribution area, it will be violently disturbed, and the flocs settled down from the inclined tube or inclined plate area will be broken, which is not conducive to the settlement of floc particles; 2. The space occupied by the water distribution area Larger, the water flow enters the water distribution area from the side of the sedimentation tank, and the water distribution is uneven along the length of the pool; 3. There is no barrier between the water distribution area and the mud bucket, and the water flow entering the water distribution area is disturbed downward due to the influence of gravity flow, which may be The flocs in the mud hopper are stirred up, which is not conducive to the settlement of the flocs. The existence of the above-mentioned problems limits the further improvement of the sedimentation efficiency of the sedimentation tank, and to a certain extent makes it less adaptable to changes in water quality and quantity.
发明内容Contents of the invention
本发明的目的是为了进一步提高现有异向流斜管或斜板沉淀池的沉淀效率，而提供一种复合沉淀池。The object of the present invention is to provide a composite sedimentation tank in order to further improve the sedimentation efficiency of the existing counterflow inclined tube or inclined plate sedimentation tank.
本发明复合沉淀池由水平流斜板组件、清水槽、沉泥槽、过渡区、排泥管、泥斗、异向流斜管或斜板、清水区和集水槽组成，在复合沉淀池的上部安装集水槽，集水槽的下方为清水区，清水区的下方为异向流斜管或斜板，而在复合沉淀池的底部设有泥斗，在泥斗上方安装排泥管；在排泥管上方沿池宽方向设置间隔排列的多个水平流斜板组件，水平流斜板组件是由平行间隔排列的斜板组成，所述的斜板与水平面存在倾角，沿斜板倾斜向下的方向在水平流斜板组件之间的区域设置沉泥槽，沿斜板倾斜向上的方向在水平流斜板组件之间的区域设置清水槽，在间隔排列的水平流斜板组件上方为过渡区，过渡区中设置有与进水方向垂直的导流板，过渡区的上方为异向流斜管或斜板。The composite sedimentation tank of the present invention is composed of a horizontal flow inclined plate assembly, a clear water tank, a sedimentation tank, a transition zone, a mud discharge pipe, a mud bucket, a different flow inclined pipe or a ramp, a clean water area and a water collection tank. The upper part is equipped with a sump, the lower part of the sump is the clear water area, and the lower part of the clear water area is a different flow inclined pipe or inclined plate, and a mud bucket is installed at the bottom of the compound sedimentation tank, and a mud discharge pipe is installed above the mud bucket; A plurality of horizontal flow sloping plate assemblies are arranged at intervals along the pool width above the mud pipe. The horizontal flow sloping plate assembly is composed of sloping plates arranged in parallel and at intervals. In the direction of the horizontal flow swash plate components, a settling tank is set in the area between the horizontal flow swash plate components, and a clean water tank is set in the area between the horizontal flow swash plate components along the direction of the inclined upward direction of the sloping plates, and a transition is made above the horizontal flow swash plate components arranged at intervals In the transition zone, there is a deflector perpendicular to the water inlet direction, and above the transition zone is a different flow inclined pipe or a sloping plate.
本发明复合沉淀池的工作过程为：水流由絮凝池末端垂直进入水平流斜板组件中，部分水流在向前流动的同时沿斜上方向流入清水槽，并沿清水槽向上流入水平流斜板组件和异向流斜管或斜板组件之间的过渡区；部分水流在向前流动的同时沿斜下方向流入沉泥槽，并由沉泥槽向上流入水平流斜板组件和异向流斜管或斜板组件之间的过渡区。流动过程中，水中的絮体颗粒沉降到斜板上，沿斜板下滑到斜板一侧的沉泥槽，并沿沉泥槽垂直沉降到底部泥斗内；没有沉降的微小絮体随水流进入过渡区。水流和未沉降的微小絮体经由过渡区进入异向流斜管或斜板内部进行二次分离，清水进入斜管或斜板上方的清水区，经集水槽集水，流出沉淀池；沉降到斜管或斜板上的絮体颗粒沿斜管或斜板下滑，经过渡区、水平流斜板组件，最终沉降到底部泥斗内。The working process of the composite sedimentation tank of the present invention is: the water flow enters the horizontal flow swash plate assembly vertically from the end of the flocculation tank, part of the water flow flows into the clear water tank along the oblique upward direction while flowing forward, and flows upward along the clear water tank into the horizontal flow swash plate The transition zone between the subassembly and the counterflow inclined tube or sloping plate assembly; part of the water flow flows into the sedimentation tank in an obliquely downward direction while flowing forward, and from the sedimentation tank upwards into the horizontal flow inclined plate assembly and the counterflow The transition zone between inclined tube or inclined plate assemblies. During the flow, the floc particles in the water settle on the sloping plate, slide down the sloping plate to the sedimentation tank on one side of the sloping plate, and vertically settle into the mud bucket at the bottom along the sloping plate; into the transition zone. The water flow and unsettled tiny flocs enter the counterflow inclined tube or inclined plate through the transition zone for secondary separation, and the clean water enters the clear water area above the inclined tube or inclined plate, collects water through the sump, and flows out of the sedimentation tank; The floc particles on the inclined tube or inclined plate slide down along the inclined tube or inclined plate, pass through the transition zone, the horizontal flow inclined plate assembly, and finally settle into the bottom mud hopper.
本发明复合沉淀池在过渡区设有与进水方向相垂直的导流板，以进一步减小水流在过渡区沿水平方向的扰动，防止絮体颗粒被打碎。在过渡区，由于下方水流向上流动和上方斜管或斜板组件内絮体向下沉降的相互作用，会形成一个泥渣悬浮层。细小絮体颗粒进入到泥渣悬浮层后会和其它颗粒碰撞、凝聚，形成较大絮体颗粒，而长大的絮体颗粒会从泥渣悬浮层沉降到水平流斜板组件内，最终沉淀去除。从而进一步提高了沉淀池的沉淀效率和出水效果。The composite sedimentation tank of the present invention is provided with a deflector perpendicular to the water inlet direction in the transition zone to further reduce the disturbance of the water flow along the horizontal direction in the transition zone and prevent the floc particles from being broken. In the transition zone, a sludge suspension layer is formed due to the interaction of the upward flow of the lower flow and the downward settling of flocs in the inclined tube or plate assembly above. After the fine floc particles enter the sludge suspension layer, they will collide with other particles and aggregate to form larger floc particles, while the grown floc particles will settle from the sludge suspension layer into the horizontal flow swash plate assembly, and finally settle remove. Thus, the sedimentation efficiency and water discharge effect of the sedimentation tank are further improved.
本发明复合沉淀池由于水平流斜板组件对进入到异向流斜管或斜板内的水流起到了预沉淀的作用，使进入到斜管或斜板内的水流浊度降低，从而可有效提高沉淀池的出水效果，减少斜管或斜板的清洗次数。而且，在原水浊度较高时，也可以保证良好的出水效果。The composite settling tank of the present invention can reduce the turbidity of the water flow entering the inclined tube or inclined plate because of the horizontal flow inclined plate assembly, which can effectively Improve the water outlet effect of the sedimentation tank and reduce the number of cleanings of inclined pipes or inclined plates. Moreover, when the turbidity of the raw water is high, it can also ensure a good water discharge effect.
当进水流量为0.5t/h，表面负荷为13.5m3/（m2·h），进水浊度为78NTU时，通过复合沉淀池处理后的出水浊度可到达1NTU以下。When the influent flow is 0.5t/h, the surface load is 13.5m 3 /(m 2 ·h), and the turbidity of the influent is 78NTU, the turbidity of the effluent treated by the composite sedimentation tank can reach below 1NTU.

具体实施方式Detailed ways
下面结合附图对具体实施方式作进一步说明：The specific implementation will be further described below in conjunction with the accompanying drawings:
具体实施方式一：本实施方式的复合沉淀池由水平流斜板组件1、清水槽2、沉泥槽3、过渡区4、排泥管5、泥斗6、异向流斜管或斜板7、清水区8和集水槽9组成，在复合沉淀池的上部安装集水槽9，集水槽9的下方为清水区8，清水区8的下方为异向流斜管或斜板7，而在复合沉淀池的底部设有泥斗6，在泥斗6上方安装排泥管5；在排泥管5上方沿池宽方向设置间隔排列的多个水平流斜板组件1，水平流斜板组件1是由平行间隔排列的斜板1-1组成，所述的斜板1-1与水平面存在倾角，沿斜板1-1倾斜向下的方向在水平流斜板组件1之间的区域设置沉泥槽3，沿斜板1-1倾斜向上的方向在水平流斜板组件之间的区域设置清水槽2，在间隔排列的水平流斜板组件1上方为过渡区4，过渡区4中设置有与进水方向垂直的导流板10，过渡区4的上方为异向流斜管或斜板7。Embodiment 1: The composite sedimentation tank of this embodiment is composed of a horizontal flow inclined plate assembly 1, a clear water tank 2, a sedimentation tank 3, a transition zone 4, a mud discharge pipe 5, a mud bucket 6, a different direction flow inclined pipe or an inclined plate 7. The clean water area 8 and the sump 9 are composed of a sump 9 installed on the top of the composite sedimentation tank. The bottom of the sump 9 is the clear water area 8, and the bottom of the clear water area 8 is a different direction flow inclined pipe or inclined plate 7. A mud hopper 6 is provided at the bottom of the compound sedimentation tank, and a mud discharge pipe 5 is installed above the mud hopper 6; a plurality of horizontal flow swash plate assemblies 1 arranged at intervals along the width direction of the tank are arranged above the mud discharge pipe 5, and the horizontal flow swash plate assembly 1 is composed of sloping plates 1-1 arranged in parallel at intervals, and the sloping plates 1-1 have an inclination angle to the horizontal plane, and are arranged in the area between the horizontal flow sloping plate assemblies 1 along the downward direction of the sloping plates 1-1 The sedimentation tank 3 is provided with a clear water tank 2 in the area between the horizontal flow swash plate components along the inclined upward direction of the swash plate 1-1, and a transition zone 4 is formed above the horizontal flow swash plate components 1 arranged at intervals. In the transition zone 4 A deflector 10 perpendicular to the water inlet direction is provided, and above the transition zone 4 is a different-flow inclined pipe or a slant plate 7 .
本实施方式复合沉淀池B-B截面的剖面图如图2所示。The sectional view of the B-B section of the composite sedimentation tank in this embodiment is shown in FIG. 2 .
本实施方式中所述的水平流斜板组件和过渡区导流板为铝板、铝合金板、不锈钢板、PVC板、UPVC板、ABS板、PE板、聚丙烯板、玻璃钢板、钢板、木板、钢塑复合板、竹子板或石棉板。The horizontal flow inclined plate assembly and the deflector in the transition zone described in this embodiment are aluminum plates, aluminum alloy plates, stainless steel plates, PVC plates, UPVC plates, ABS plates, PE plates, polypropylene plates, glass steel plates, steel plates, and wood plates , steel-plastic composite board, bamboo board or asbestos board.
本实施方式的复合沉淀池通过在传统异向流斜管或斜板沉淀池配水区设置水平流斜板组件，可使沉淀池配水更加均匀，并且使水流的流动更加稳定，控制其内水流的水平流速为5mm/s～50mm/s，不易将沉淀下来的絮体搅起或打碎。同时水平流斜板组件还对进入到异向流斜管或斜板组件的水起到了预沉淀的作用，减轻了异向流斜管或斜板的进水负荷，使出水水质更好，异向流斜管或斜板组件清洗周期更长。The composite sedimentation tank of this embodiment can make the water distribution of the sedimentation tank more uniform, make the flow of water flow more stable, and control the flow of water in the sedimentation tank The horizontal flow rate is 5mm/s~50mm/s, which is not easy to stir up or break the settled flocs. At the same time, the horizontal flow inclined plate assembly also plays a role in pre-sedimentation of the water entering the inclined flow pipe or inclined plate assembly, reducing the water inlet load of the inclined pipe or inclined plate with different direction flow, so that the quality of the effluent water is better, and the Longer cleaning intervals for inclined flow tube or inclined plate assemblies.
由于水平流斜板组件的限制，水流在由水平流斜板组件流动到异向流斜管或斜板组件和水平流斜板组件之间的过渡区时水流流动的雷诺数降低，水流紊动性减小，流速降低，絮体颗粒不易被打碎，同时水流的分布更加均匀。此外，由斜板下滑到沉泥槽的絮体颗粒基本不受水平作用力的影响，因此沉淀更稳定，效果更好。而且，水平流斜板组件的设置使泥斗和沉淀区相对独立，沉淀到泥斗的絮体不易被搅起。Due to the limitation of the horizontal flow swash plate assembly, the Reynolds number of the water flow decreases when the water flow flows from the horizontal flow swash plate assembly to the counter flow inclined tube or the transition zone between the swash plate assembly and the horizontal flow swash plate assembly, and the water flow is turbulent The property is reduced, the flow rate is reduced, the floc particles are not easy to be broken, and the distribution of water flow is more uniform. In addition, the floc particles that slide down from the inclined plate to the sedimentation tank are basically not affected by the horizontal force, so the sedimentation is more stable and the effect is better. Moreover, the setting of the horizontal flow swash plate assembly makes the mud hopper and the sedimentation area relatively independent, and the flocs settled in the mud hopper are not easy to be stirred up.
本实施方式在过渡区中设置与进水方向相垂直的导流板，以进一步减小水流在过渡区沿水平方向的扰动，防止絮体颗粒被打碎。在过渡区，由于下方水流向上流动和上方斜管或斜板组件内絮体向下沉降的相互作用，会在过渡区形成一个泥渣悬浮层，细小絮体颗粒进入到泥渣悬浮层后会和其它颗粒碰撞、凝聚，形成较大絮体颗粒，而长大的絮体颗粒会从泥渣悬浮层沉降到水平流斜板组件内，最终沉淀去除，从而进一步提高了沉淀池的沉淀效率和出水效果。In this embodiment, deflectors perpendicular to the water inlet direction are provided in the transition zone to further reduce the disturbance of water flow along the horizontal direction in the transition zone and prevent floc particles from being broken. In the transition zone, due to the interaction between the upward flow of the lower water flow and the downward settlement of the flocs in the upper inclined tube or inclined plate assembly, a sludge suspension layer will be formed in the transition zone, and the fine floc particles will enter the sludge suspension layer. Collision and coagulation with other particles to form larger floc particles, and the grown floc particles will settle from the sludge suspension layer into the horizontal flow swash plate assembly, and finally be removed by sedimentation, thereby further improving the sedimentation efficiency of the sedimentation tank and water effect.
