Reason.In the prior art, sludge is concentrated generally by gravity concentration method, Bubble-floating Method and centrifugal concentrating method.
Gravity concentration method is that sludge is transported to sludge concentration tank, and sludge settling is made by way of natural subsidence to pond
Bottom, and correspondingly discharge supernatant.Extremely grown however, this gravity concentration method using natural subsidence takes, generally require length
Up to 10 when small more than time can complete sedimentation separation.In addition, long time-consuming and cause the sludge for being deposited in bottom of pond to be formed to detest
Oxygen environment, so as to cause dewatered P content in sludge higher, does not reach discharge standard.In Chinese utility model patent
A kind of sludge concentration tank is proposed in CN205011601U, its by being aerated and stirring the contact to increase sludge with oxygen, from
And reduce the release of phosphorus in sludge.But due to the effect for being aerated and stirring so that sludge is more difficult to by natural subsidence
Mode concentrates and accordingly discharges supernatant.Therefore, although the program reduces the release of phosphorus in sludge, but causes sludge dense

Mud floats.And centrifugal concentrating rule need carried out in the Centrifugal concentrators being specifically manufactured, its utilize sludge in solid, liquid proportion not
Together, there are different tendency to drift aways, muddy water is thus separated, so as to achieve the purpose that concentration.However, centrifugal concentrating method needs to use
Complicated and expensive special equipment, thus higher expense can be caused.
In addition, in order to which processing is effectively performed in the sludge high to moisture content, in addition to being concentrated to sludge, it is also necessary to
It is quenched to sludge progress for the characteristic of sludge, in order to which follow-up mechanical dehydration and desiccation etc. are handled.This is because sludge has
