And dephosphorization；Biomembrance process is located at below liquid level using being aerated from aeration and biological runner from the 80% of aeration and biological runner, its
Rotating speed is 0.5-2r/min, has mounted fibre bundle bionic filler inside it, the specific surface area of fibre bundle bionic filler is 3200-
4500m2/m3；Granular filler is delivered in the sewage of aerobic zone, granular filler injected volume is the 45%-55% that aerobic zone pond holds；It is dirty
Water is filled out after the stirring from aeration and biological runner and the boring aeration pipe of aerobic zone bottom of pond with fibre bundle bionic filler and particle
Material fully contact, occurs nitration reaction, and nitrification liquid is back to aerobic area by air lift technology and carries out denitrification, the backflow of nitrification liquid
Than for 100%-300%, remaining sewage enters settling zone by filter, and granular filler is intercepted by filter；
(3) sewage treated through (2) isolates gas, mud mixture and sludge through three phase separator again into settling zone,
The inclined plate separator that mud mixture is risen to above three phase separator isolates sludge and supernatant, and supernatant is received through outlet pipe
Discharged after collection sterilization is qualified, the sludge that three phase separator and inclined plate separator are isolated is slided with the slope below three phase separator
Fall, amount of activated sludge comes back to aerobic zone end, excess sludge is discharged from sludge outlet, the sludge discharged from sludge outlet
Timesharing carries out sludge reflux and directly discharged, the nitrification liquid that sludge reflux to aerobic area flows back with pending sewage and aerobic zone
Mixing, the sludge directly discharged is discharged to sludge-tank.
