Description
Technical Field
The utility model relates to sewage treatment, in particular to a self-rotating multilayer flow control uniform water inlet device used in sewage tank treatment.
Background
Many process monomers in the sewage treatment process need to ensure that water is uniformly fed to the bottom and water is uniformly received to the top. In practical cases, a great number of sewage flows in the tank body can form partial short flow because of the tank shape and can not well and evenly enter and exit water, and the treatment effect is affected.
In many engineering cases, the water inlet at the bottom considers a main water inlet pipe in the middle and two side-distributed row-shaped water distribution branch pipes. Although the mode is simple and easy to implement, the uniformity of water distribution is different due to different delay losses of the pipelines, so that the water flows of the tail end water and the initial section are different, and the effect of uniform water inflow at the bottom cannot be achieved. When the tank shape is smaller, water can be distributed relatively uniformly. When the tank shape is bigger, the uniformity of water distribution is not guaranteed and controlled well, that is to say, the tank shape of the process monomer with bigger treatment scale is too big, if the arrangement of the conventional bottom water distribution system is adopted, the water outlet points at the far end and the near end have different resistances due to different lengths of pipelines, so that the water inlet at the bottom is uneven, and the treatment effect is affected.
