the wastewater deposited in the primary and secondary sedimentation tank contains a large amount of sludge, and the sludge floc is light, which is easy to be carried away by water< Second, sludge has a certain viscosity
Third, the space in the inclined pipe is very small, and it is easy to be attached to the wall, and it is easy to be blocked< Fourth, the inclined pipe is not concive to observe the height of the mud surface, which leads to the occurrence of turbidity in the effluent or the increase of flocculus in the effluent of the secondary sedimentation tank, and the reason can not be judged timely and accurately< 5. The principle that the inclined plate can improve the sedimentation efficiency is mainly applicable to free sedimentation, but in the secondary sedimentation tank, the sedimentation form mainly belongs to layered sedimentation rather than free sedimentation.

of course, it is related to the specific reactor structure. Some circulating fluidized beds are also equipped with rotary separators to ensure that cat does not run away or less
