Certain biopharmaceutical company mainly uses biological fermentation process to produce kitasamycin, colistin sulfate, tylosin, discharge High gravity fermentation class antibiotic waste water be mainly butyl acetate recycling waste water, device ground cleaning waste water, pressing filtering liquid, absorption tail Liquid, acid-basic regenerated waste liquids in water and flushing water, concentrating spent liquor etc..Comprehensive wastewater COD concentration after mixing is 12000mg/L, ammonia nitrogen For 450mg/L, TN 1000mg/L, total phosphorus 40mg/L, SO₄ ^2-For 5000mg/L.

Original system design using " hydrolysis acidification+A/O+ two heavy+coagulating sedimentation " treatment process, in actual moving process In, there are following problems: hydrolysis acidification pool can not play thorough detoxication to antibiotic waste water, influence back segment biochemical treatment effect Fruit；The pond the A residence time is short in A/O technique, and water outlet total nitrogen is easy exceeded；Without advanced treatment system, aqueous concentration is higher, Wu Faman Foot requirement up to standard.

Blowdown condition, existing sewerage operating condition in conjunction with the factory carry out upgrading to the factory, in major alterations Hold as follows: for the high feature of fermentation waste water concentration of suspension, increasing preliminary sedimentation tank precipitation and separation suspended matter, improve raw water quality； Newly-built Anaerobic Treatment unit, degrades to the organic pollution materials in raw water using two-stage EGSB anaerobic reactor, after reduction Continuous Aerobic Process for Treatment system operating load, saves operating cost；Newly-built advanced treatment unit, increases catalytic ozonation pond and IBF, By the synergy of catalytic ozonation and depth aerobic biochemical, remaining polluter in depth degradation waste water, it is ensured that go out Water qualified discharge.

Improved system structure is as shown in Figure 1, include sequentially connected pretreatment unit, Anaerobic Treatment unit, aerobic Processing unit and advanced treatment unit；The pretreatment unit includes: in sequentially connected pH and device 1 and primary sedimentation tank 2；It is described Anaerobic Treatment unit includes: preparing pool 3, level-one EGSB anaerobic reactor 4 and second level EGSB anaerobic reactor 5；The aerobic place Reason unit includes: sequentially connected hydrolysis acidification pool 6 and multistage multistage A/O reaction tank 7；The advanced treatment unit include: according to Efficient sedimentation tank 8, catalytic ozonation pond 9 and the IBF10 of secondary connection.Primary sedimentation tank, multistage multistage A/O reaction tank and High-rate sedimentation The sludge outlet in pond is connect with sludge dewatering system 11.

Wherein, the structure of isolated aeration biofilter 10 is as shown in Fig. 2, include water distributing area 1002, supporting layer 1004, filler Area 1005, clear water zone 1006, aeration cycle cylinder 1013.Packing area 1005 is located at the top of water distributing area 1002, between two regions It is to be connected to using water distribution flase floor 1003；1005 top of packing area is clear water zone 1006, and the top of clear water zone 1006 is equipped with collection Mill weir slot 1007；Water enters water distributing area 1002 by water inlet 1001, enters back into supporting layer 1004, then enters back into packing area 1005, after producing water by the collection of weir notch 1007 of catchmenting, discharged by water outlet 1008.Pass through aerator in aeration cycle cylinder 1013 1014 aeration (enters) castering action from aeration opening 1009, and the water in clear water zone 1006 is back to through recycling diversion pipe 1015 Water distributing area 1002 promotes the upflow velocity in biofilter, can pollutant is more evenly distributed in filter material layer, improves anti- Answer the volumetric efficiency of device.

After isolated aeration biofilter runs some cycles, due to the suspension pollutant matter and biomembrane in retention waste water The reasons such as increment is excessive need periodically to realize system regeneration by backwash.The backwash regeneration of reactor uses " air water Joint is rinsed " mode, independent air purge is first carried out by 1010 air inlet of backwash air inlet when backwash, air purge for a period of time after, instead It washes the water inlet of water inlet 1011 and carries out air water joint flushing, be then shut off backwash air inlet 1010 and individually washed, arranged from backwash The mouth of a river 1012 is discharged.Isolated aeration biofilter is using air lift circulation, the method for operation of upward flow, and pollutant carrying capacity is stronger, therefore More traditional BAF has longer backwashing period.
