Row muddy water initial gross separation, supernatant is discharged by drainpipe 32 and is back to water process link and handled, and the sludge after precipitation is then
Enter through discharge pipeline 33 in filter press 4 and carry out filter-press dehydration, because the cell membrane and capillary in excess sludge are entirely destroyed,
The main surface water to be easy to press filtration removing of moisture in excess sludge is present, therefore moisture content drastically drops after excess sludge press filtration
It is low, realize that city domestic sewage handles the target of plant excess sludge deep dehydration.
The utility model destroys the flocculation structure of sludge using Centrafugal speed accelerator, improves the sedimentation effect and muddy water point of sludge
Effect, and the cell wall structure and capillary pipe structure that are destroyed using ultrasonic combined Hydrodynamic Cavitation Technology in excess sludge,
The difficult capillary water removed and intracellular water is changed into the surface water easily removed, substantially increase sludge dewatering efficiency, have compressed dirt
Mud amount, meanwhile, during system operation, the addition of no chemical agent is not likely to produce secondary pollution, and the chemical property of sludge changes
Become little, be conducive to its follow-up recycling.
