Stream, vortex, short stream and the phenomenon such as stagnant water and deposition；Using square more in conventional precipitation the pond, and fluidised form is in pulling flow type in pond, is easily made
Short circuit phenomenon into the local stagnant water in end, deposition and current occurs, and baffling sedimentation basin employs recycle stream in fluidised form
Fluidised form, can be prevented effectively from the generation of above-mentioned phenomenon, and the loss of flood peak is smaller；
(4) current fluid field is evenly distributed, and pond body capacity utilization is high；Because baffling sedimentation basin employs the stream of recycle stream
State, the overall current presented in more rational fluid field distribution, pond body are unimpeded, can be improved its capacity utilization；
(5) deposition efficiency is high：It is clear water layer, outstanding due to there is obvious annular fluidised form and density current in baffling sedimentation basin
Had between three levels such as floating layer and sludge blanket and good suspending clarification effect occur in clear interface, superposed layer,
And then higher deposition efficiency can be obtained；
(6) it can be built jointly with the common wall of biochemical treatment unit, make full use of vertical space, save and take up an area and construction period, reduction
Civil engineering costs and operating cost；For baffling sedimentation basin is compared with other conventional precipitation ponds, spoil disposal water inlet system is more simple, can be with life
Change processing unit wall or bottom plate altogether, greatly save floor space and construction period, simultaneously because the reduction of structures quantities,
Also civil engineering costs and operating cost be reduce further.
