Description
技术领域technical field
本实用新型涉及一种推流井，属于污水处理领域，广泛应用于混凝沉淀池中。The utility model relates to a push flow well, which belongs to the field of sewage treatment and is widely used in coagulation sedimentation tanks.
背景技术Background technique
高效沉淀池分为加药区和沉淀区，为提高药剂利用率，增加污染物的去除效果，提高沉淀区中泥水的分离效果。本实用新型在加药区和沉淀区之间设置推流井，采用推流井使絮凝区形成的矾花充分压实，并对水流起到稳流的作用，提高后续水和絮体分离效果，提高沉淀速度。The high-efficiency sedimentation tank is divided into a dosing area and a sedimentation area. In order to improve the utilization rate of chemicals, increase the removal effect of pollutants, and improve the separation effect of mud and water in the sedimentation area. The utility model sets a push well between the dosing area and the sedimentation area, and uses the push well to fully compact the alum flowers formed in the flocculation area, and plays a role in stabilizing the water flow, improving the subsequent separation effect of water and flocs , to increase the precipitation rate.
实用新型内容Utility model content
本实用新型所述的一种推流井是由进水墙、收水坡、分流墙、出水墙组成。A pushing flow well described in the utility model is composed of a water inlet wall, a water receiving slope, a diversion wall, and a water outlet wall.
所述的进水墙底部设进水孔，进水孔过水流速0.01～0.05m/s。特别地，进水孔的过水流速要大于进水墙与出水墙组成区域的水流速度，目的在于既避免絮凝区形成的矾花在该区域被打散，又避免矾花在此沉降。A water inlet hole is provided at the bottom of the water inlet wall, and the water flow rate through the water inlet hole is 0.01-0.05m/s. In particular, the water flow velocity of the water inlet hole is greater than the flow velocity of the area formed by the water inlet wall and the water outlet wall. The purpose is to prevent the alum flowers formed in the flocculation area from being broken up in this area, and to prevent the alum flowers from settling here.
所述的收水坡，包括侧收水坡和中央收水坡，同时坡向进水孔，收水坡与池底呈坡角40°～60°坡角，避免出现死水区。The water collection slope includes a side water collection slope and a central water collection slope. At the same time, the slope faces the water inlet, and the water collection slope and the bottom of the pool form a slope angle of 40° to 60° to avoid dead water areas.
所述的分流墙起将水流均匀地分成两部分，起到均匀水流的作用。分流墙为不规则形状，与收水坡垂直，分流墙与池底面不相接。The divider wall evenly divides the water flow into two parts and plays the role of uniform water flow. The diversion wall is irregular in shape, perpendicular to the water collection slope, and the diversion wall is not in contact with the bottom of the pool.
本实用新型所述的推流井可根据尺寸大小设置为混凝土结构或者钢结构。The plug flow well described in the utility model can be set as a concrete structure or a steel structure according to the size.
本实用新型所述的推流井设置在高效沉淀池的絮凝区与沉淀区之间。采用推流井使絮凝区形成的矾花充分压实，并对水流起到稳流的作用，提高后续水和絮体分离效果，提高沉淀速度。The push flow well described in the utility model is arranged between the flocculation area and the sedimentation area of the high-efficiency sedimentation tank. The plug flow well is used to fully compact the alum flowers formed in the flocculation area, and to stabilize the water flow, improve the separation effect of subsequent water and flocs, and increase the sedimentation speed.

具体实施方式Detailed ways
以下结合附图对本实用新型的具体实施方式作进一步详细说明。The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.
污水在絮凝区经过投加絮凝剂后，形成矾花，卷积着污染物的矾花随水流通过进水墙1的过水孔2，并沿着收水坡3、4，自下而上经过分流墙5将水流平均分成两股，该过程中矾花一直随污水流动，只有很少一部分比重较大的会沉积在井底。经过分流墙5的污水最后经出水墙6上的过水堰进水后续沉淀区进行泥水分离。After the sewage is added with flocculant in the flocculation area, alum flowers are formed, and the alum flowers convoluted with pollutants pass through the water hole 2 of the water inlet wall 1 with the water flow, and along the water collection slopes 3 and 4, from bottom to top The water flow is evenly divided into two streams through the diversion wall 5. During the process, the alum flowers flow with the sewage all the time, and only a small part with a larger specific gravity will be deposited at the bottom of the well. The sewage passing through the diversion wall 5 finally passes through the weir on the outlet wall 6 and enters the subsequent sedimentation area for mud-water separation.
本实用新型所述的推流井，不局限设置于高效沉淀池中，也适合设置在相关混凝沉淀工艺及所有需对水流进行稳流的工艺。The push flow well described in the utility model is not limited to be installed in high-efficiency sedimentation tanks, but is also suitable for installation in related coagulation and sedimentation processes and all processes that need to stabilize the water flow.
