斜管沉淀池是根据浅池沉淀理论设计出的一种组合式沉淀池；也称为浅池沉淀池。在沉降区域设置许多密集的斜管或斜板，使水中悬浮杂质在斜板或斜管中进行沉淀，水沿斜板或斜管上升流动。分离出的泥渣在重力作用下沿着斜板（管）向下滑至池底，再集中排出。这种池子可以提高深沉效率50-60%，在同一面积上可提高处理能力3-5倍。The inclined tube sedimentation tank is a combined sedimentation tank designed according to the shallow tank sedimentation theory; also called the shallow tank sedimentation tank. Set up many dense inclined pipes or inclined plates in the settlement area, so that the suspended impurities in the water are precipitated in the inclined plates or inclined pipes, and the water flows upward along the inclined plates or inclined pipes. The separated sludge slides down the inclined plate (tube) to the bottom of the pool under the action of gravity, and then is discharged in a concentrated manner. This kind of pool can increase the deep sinking efficiency by 50-60%, and the processing capacity can be increased by 3-5 times on the same area.
可根据原废水的试验数据来设计不同流量的斜管沉淀器，使用时一般都要投加凝聚剂。斜管沉淀净水法是在泥渣悬浮层上方安排倾角60度的斜管组建，使原水中的悬浮物，固体物经投加混凝剂后形成的絮体矾花，在斜管侧表面积积聚成薄泥层，依靠重力作用滑回泥渣悬浮层，继而沉入集泥斗。由排泥管排入污泥池另行处理或综合利用。上清液逐渐上升至集水管排出，可直接排放或回用。The inclined tube precipitator with different flow rates can be designed according to the test data of the original wastewater, and coagulant is generally added during use. Inclined tube sedimentation water purification method is to arrange an inclined tube with an inclination angle of 60 degrees above the sludge suspension layer, so that the suspended matter in the raw water and the solid matter are formed after adding coagulant to the side surface area of the inclined tube. It accumulates into a thin layer of mud and slides back to the suspended mud layer by gravity, and then sinks into the mud bucket. Drain into the sludge tank from the sludge pipe for separate treatment or comprehensive utilization. The supernatant liquid gradually rises to the water collecting pipe and can be discharged directly or reused.
斜管沉降比竖流沉降速度更快，很多人认为是斜管的沉淀距离缩短了，所以沉的快。其实这是表象。本质上是浅层沉淀，因为两根试管及里面的含杂质水条件完全相同，也就是池容相同，但试管倾斜后沉淀面积增大了（同时带来了沉降距离减小），所以杂质颗粒能更快地沉到倾斜管壁上，并迅速聚集到池底而被去除。The sedimentation speed of the inclined pipe is faster than that of the vertical flow. Many people think that the sedimentation distance of the inclined pipe is shortened, so the sedimentation is fast. In fact, this is the appearance. It is essentially shallow sedimentation, because the two test tubes and the impurity-containing water conditions are exactly the same, that is, the pool volume is the same, but the sedimentation area increases after the test tube is tilted (at the same time, the sedimentation distance is reduced), so the impurity particles It can sink to the inclined pipe wall faster, and quickly gather to the bottom of the pool to be removed.
斜板沉淀器/斜管沉淀器，根据进出水的水流方向，主要分为三类：同向流(下向流)斜板沉淀池、异向流(上向流)斜板沉淀池、侧向流斜板沉淀池。使用最广泛的是异向流(上向流)斜板沉淀器，水流从斜管沉淀池的斜板/斜管填料下部进水，水中的颗粒沉淀在斜板/斜管上，并顺着倾斜的斜板/斜管向下滑入泥斗，分离后的清水自设备上部的集水装置排出斜管沉淀器。Inclined plate settler/inclined tube settler, according to the direction of water flow in and out of the water, it is mainly divided into three categories: same flow (downward flow) inclined plate sedimentation tank, different flow (upward flow) inclined plate sedimentation tank, side Flow sloping plate sedimentation tank. The most widely used is the counter-flow (upward flow) inclined plate settler. The water flows from the lower part of the inclined plate/inclined tube packing of the inclined tube sedimentation tank, and the particles in the water settle on the inclined plate/inclined tube and follow. The inclined inclined plate/pipe slides down into the mud bucket, and the separated clean water is discharged from the inclined pipe settler from the water collecting device on the upper part of the equipment.
