Specific embodiment

Below in conjunction with attached drawing, invention is further described in detail.

Referring to Fig.1, be a kind of sludge dewatering processing system disclosed by the invention, including pretreatment unit, regulating device with And dehydration device.Pretreatment unit includes rubbish seperator 1, garbage pool 2, silt seperator 3, storage basin 5；Regulating device includes Dosing pond 14 and concentration tank 10；Dehydration device includes belt filter press 11.

As shown in Figure 1, sludge to be treated is fed through rubbish seperator 1, rubbish under the action of sludge pumping mechanism Seperator 1 is removed the rubbish contained in sludge, and the rubbish isolated is fed through in garbage pool 2, and the later period can be to rubbish Centralization processing is carried out, and the sludge after separating enters in silt seperator 3, silt seperator 3 is to contained in mud Fine sand is filtered, and filtered fine sand is entered in fine sand pond 4 and stored, and the later period can be recycled fine sand.

Treated that sludge drains to storage basin 5 for silt seperator 3, and storage basin 5 carries out preliminary sedimentation to sludge；By first Supernatant liquor second-level settling pond 7 after precipitating, storage basin 5 are connected with concentration tank 10, and dosing pond 14 is to storage basin 5 and concentration tank 10 Between pipeline in add medicament, and then improve dewatering；Sludge is passed through belt filter press 11 again to be dehydrated, is completed de- The step of water；Before dehydration, dosing pond 14 carries out secondary dosing into the pipeline between concentration tank 10 and belt filter press 11.Dehydration Mud water content afterwards is small, is sent to mud cake workshop 14 by conveyer belt and is stored；Generated water passes through reflux after dehydration Pipe 12 comes back to storage basin 5 and is precipitated, repetitive cycling, reduces the content of mud in water in second-level settling pond 7, and process is secondary Sludge after precipitating is entered in three-level sedimentation basin 8 and is precipitated three times, and the water after precipitating three times enters after being relatively close together To clear water reserviors 9, the water in clear water reserviors 9 can be directly discharged in river or reuse；Second-level settling pond 7 and three-level are heavy Regularly 10 sludge for being conveyed through precipitating into concentration tank of shallow lake pond 8.

Water in dosing pond 14 can be fed through dosing pond 14 by the effect of water pump, be used for using the water in clear water reserviors 9 It is deployed with chemical agent, realizes the recycling of water resource, the water in clear water reserviors 9 can be used for irrigating, clean vehicle The effects of.

Before entering back into conditioning device due to sludge, by storage basin 5, second-level settling pond 7, three-level sedimentation basin 8 it is heavy It forms sediment, the supernatant liquor for entering to clear water reserviors 9 is more clean, and garbage sorting machine 1 and silt point can be cleaned with the water in clear water reserviors 9 Disembark 3；Water circulation between second-level settling pond 7 and conditioning device, so as to reduce in second-level settling pond 7 containing for mud in water Amount, after water is precipitated using three-level sedimentation basin 8, water is relatively clean, may be reused.

The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it It is interior.
