One of the baffled sedimentation tank of the present invention and deflector type depositing technology, at least have the advantages that：
(1) can solve the problems, such as that sedimentation tank effluent weir load is larger well, and larger surface loading can be adopted；
The height of effluent weir load determines water outlet streamflow regime, and load is too high to arise that profile of tooth weir is used as flat weir, Jin Erying
Ring effluent quality；Sedimentation tank load height determine precipitation pool area, also determine outlet effect and construction investment, load low go out
Water effect is good, construction investment height；Conversely, outlet effect is poor, construction investment is low.Effluent weir load and sedimentation tank load are between the two
Without necessary connection, but outlet effect can be affected；Baffling sedimentation tank is precipitated with respect to other due to arranging along pond length direction
The load of Chi Danweiyan length substantially can reduce, and water outlet can be made to keep a uniform and stable flow velocity, prevent sludge and scum silica frost
Excessive；Simultaneously because unit effluent weir load is minimized, surface loading therefore can be suitably improved；
(2) surface loading is larger, and floor space is less；It is the same as those described above, as baffling sedimentation tank other sedimentation tanks relative can
Properly increasing sedimentation tank takes in the case of its surface loading, namely same size land resource can be relatively small；
(3) exist and recycle stream fluidised form is thoroughly mixed, water inlet water-flow equation is uniform, can be prevented effectively from the urgency in conventional precipitation pond
Stream, vortex, short stream and the phenomenon such as stagnant water and deposition；Using square more than conventional precipitation pond, and in pond, fluidised form is in pulling flow type, easily makes
The short circuit phenomenon of stagnant water, deposition and the current of end local is become to occur, baffling sedimentation tank 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 less；
(4) current fluid field is evenly distributed, cell body capacity utilization height；As baffling sedimentation tank employs the stream of recycle stream
State, integrally assumes more rational fluid field distribution, and the current in cell body are unimpeded, are improved can its capacity utilization；
(5) deposition efficiency height：Due to there is obvious annular fluidised form and density current in baffling sedimentation tank, clear water layer, outstanding
Clearly separating surface is had between three levels such as floating layer and sludge blanket, good suspending clarification effect in superposed layer, occurs,
And then higher deposition efficiency can be obtained；
(6) can build jointly with the common wall of biochemical treatment unit, vertical space be made full use of, is saved and take up an area and construction period, reduce
Civil engineering costs and operating cost；Baffling sedimentation tank is compared with for other conventional precipitation ponds, and spoil disposal water inlet system is more simple, can be with life
Change processing unit wall or base plate altogether, floor space and construction period is greatlyd save, simultaneously because the minimizing of structures quantities,
Also civil engineering costs and operating cost reduce further.
