Step 1: Industrial Waste Water Treatments plant tail water is sent in stirring pool and is sufficiently mixed with Powdered Activated Carbon；
Step 2: the gravity flow of stirring pool charcoal water mixed liquid enters one-level charcoal water separator and carries out charcoal water flash trapping stage；
Step 3: the charcoal slurry part that one-level charcoal water separator is isolated is back to stirring pool, and another part is immediately discharged to filter pressing and sets
Standby be dehydrated after send into charcoal again generating apparatus, join charcoal pond and carry out regenerating, recycle；The water that one-level charcoal water separator is isolated send
Enter Buffer Pool；
Step 4: after former charcoal and impregnation liquid are sufficiently mixed dipping in impregnating equipment, send into dry, roasting in roasting apparatus, bear
Carry the former charcoal after metal and send into and join charcoal pond；
Step 5: water after Buffer Pool is buffered, join the Powdered Activated Carbon water that charcoal pond prepares and send into two grades of charcoal water separators and be mixed into
Row secondary separation, the water qualified discharge isolated, the charcoal slurry isolated all is back to stirring pool.
6. method according to claim 5 it is characterised in that: be sufficiently mixed described in step 1, be Industrial Waste Water Treatments factory
The tail water time of staying 0.8 hour ~ 1.2 hours in stirring pool, in stirring pool, charcoal slurry concentration reaches 8000mg/l ~ 12000mg/l.
7. method according to claim 5 it is characterised in that: flash trapping stage described in step 2, charcoal water mixed liquid is in one-level
The time of staying 0.8 hour ~ 1.2 hours in charcoal water separator, the dust active carbon slurry concentration 45600mg/l ~ 68400mg/l isolating.
8. method according to claim 5 it is characterised in that: the charcoal that the water separator of one-level charcoal described in step 3 is isolated
Slurry 96% ~ 94% is back to stirring pool, and 4% ~ 6% is immediately discharged to filtering equipment carries out dehydration regeneration recycling, and one-level charcoal water separates
The water that device is isolated sends into Buffer Pool, and in Buffer Pool, the time of staying is 12 minutes ~ 18 minutes.
9. method according to claim 5 it is characterised in that: in step 4, impregnation liquid is the nitre containing metal active constituent
Acid salt solution.
10. method according to claim 5 it is characterised in that: water after Buffer Pool being buffered described in step 5, join charcoal
The Powdered Activated Carbon water that pond prepares is sent into two grades of charcoal water separator mixing and is carried out secondary separation, stops in two grades of charcoal water separators
0.4 hour ~ 0.6 hour time, two grades of charcoal water separator charcoal slurry concentration are 32000mg/l ~ 48000mg/l.
