Flocculation And Sedimentation Sludge Screw Press Dewatering
Machine
Magnetic Flocculation Sedimentation Technology Process
1. The sewage to be treated enters the reaction tank through the
sewage lift pump, and is mixed with the added coagulant evenly and
then flows into the coagulation reaction tank. Stabilize the flocs.
Since the specific gravity of the magnetic powder is 5 times that
of water, the specific gravity of the flocs combined with the
magnetic powder increases rapidly, and the magnetic flocs flow into
the flocculation reaction pool by themselves, and mix and react
with the flocculant to form denser magnetic flocs. The mass flows
into the clarifier;
2. After the flocs containing the magnetic powder flow into the
clarifier, the sedimentation can be completed quickly, and the
sedimentation speed can reach 40 meters per hour, which is 20 times
that of the traditional coagulation sedimentation. The magnetic
process uses coagulation, flocculation, and bridging. The magnetic
sludge at the bottom of the clarifier is discharged into the
magnetic sludge transfer tank through the sludge discharge system, and the supernatant liquid passes through the clarifier.
Discharge from the water collection system, the effluent quality of
SS can reach below 5mg/L, and TP can reach below 0.3mgL, which also
has a good removal effect on COD, BOD, bacteria, etc. in sewage.
3. The magnetic sludge is sent to the high-speed shearing machine
through the sludge pump for pulverization of flocs, and then flows
into the magnetic seed recycling machine for magnetic seed recovery
and recycling. The remaining sludge flows into the sludge tank, and
the sludge passes through the sludge.
