10. a kind of implementation method of sludge dewatering system, it is characterised in that: including flocculant solution manufacturing step, mixing step
And dehydration,
Flocculant solution manufacturing step opens the first agitating device (512) and the second agitating device (522), by flocculant and water
Investment first is mixed case (51) and is mixed, and the first solution that case (51) are mixed enters second and case (52) are mixed
After continue to be stirred it, second be mixed solution for manufacture in case (52) send to flocculant storage bin (53) store with
It is spare；In flocculant solution manufacturing step, three liquidometers in flocculant storage bin (53) detect its liquid level, liquid level
When reaching high-order, stop adding water and flocculant to the first mixing case (51)；When liquid level is in middle position, stirred to the first mixing
It mixes case (51) and adds water and flocculant；When liquid level is in low level, sludge dewatering system is shut down；
Mixing step opens main agitating device (21), into dredge pump (33) and dosing pump, flocculant solution and sewage is sent to folded spiral shell
Agitator tank (2) is stirred, so that flocculant solution and sewage come into full contact with and reacts；In mixing step, dosing pump continues work
Make, into dredge pump (33) discontinuous operation；When liquid level in folded spiral shell agitator tank (2) reaches a high position for detection, stop work into dredge pump (33)
Make, after a period of time by setting, is again started up into dredge pump (33)；
Dehydration, the mixture in folded spiral shell agitator tank (2), which is sent to sludge dewatering equipment (1), to be dehydrated；In dehydration, sludge
The cleaner liquid of dewaterer (1) front end discharge, is expelled directly out sludge dewatering equipment (1) and is further processed；After sludge dewatering equipment (1)
It holds the sewage backflow of discharge to sludge box (3), continues new round processing.
