a sewage treatment pool

Abstract

The invention provides a sewage treatment tank. The sewage treatment tank is characterized by comprising a cylindrical tank body, a water inlet formed in one side of the cylindrical tank body, a water outlet formed in the other side of the cylindrical tank body, and three layers of vertical filtering layers which are arranged at the bottom of the tank body in parallel, wherein the two ends of the three layers of filtering layers are connected with the wall of the tank body; the three layers of filtering layers are arrayed from the water inlet end in sequence, namely a filtering plate layer, a ceramic filtering material layer and a fiber ball filtering material layer; spaces among the filtering layers are buffering grooves; the horizontal section of the filtering plate layer is V-shaped; the horizontal sections of the ceramic filtering material layer and the fiber ball filtering material layer are arrayed in a circular arc shape; and the filtering plate layer comprises a concrete filtering plate body and filtering holes which are uniformly formed in the filtering plate layer in parallel. By adopting the cylindrical tank body, the using area can be enlarged and the treatment water amount is increased.

Description

technical field [0001] The invention relates to a sewage treatment pool and belongs to the technical field of water treatment. Background technique [0002] At present, the sewage containing impurities is mainly treated by digging pits and sedimentation. For example, the sewage containing a large amount of stone powder generated when the stone is cut with water is generally directly discharged into the sedimentation tank. After a long period of precipitation, a large amount of stone powder will accumulate in the pool. The sediment needs to be removed after a certain period of time. This treatment method is time-consuming and laborious. The treatment is not timely and very slow. After a long time, the location of the sedimentation tank needs to be changed. Contents of the invention [0003] The present invention is exactly a kind of sewage treatment pool that proposes in view of the above problems. [0004] A sewage treatment pool, characterized in that: the sewage treatme...
