The invention provides a micro-
electrolysis-Fenton-EGSB-A / O-BCO-BAF-coagulation treatment pharmaceutical
wastewater system. The
system composition comprises an
oil separation pool, a regulation
pool, a micro-electrolytic reaction
pool, a Fenton
catalytic oxidation tower, a horizontal flow type primary
sedimentation pool, an integrated regulation pool, a
hydrolysis acidification pool, a swell granule
sludge bed, an anoxia / aero-biotic pool, a two-stage biological contact oxidation pool, and a secondary
sedimentation pool, a biological aerated filter pool, a coagulating pool, an air floating tank and an end
sedimentation tank; wherein 200t / d low concentration pharmaceutical and 50t / d domestic
sewage are input to the integrated regulation pool and fully mixed with
wastewater, after the
dilution, the COD concentration is reduced, and the biodegradability of the
wastewater is increased, after jointly going into the follow-up process
system for
processing, the wastewater reaches the standard and is discharged; the flat flow type primary sedimentation pool, the secondary sedimentation pool, the coagulating pool, the BAF pool and the end sedimentation and the
sludge concentration are connected, and are connected with the plate-and-frame press filter
machine; the
sludge of each pool is collected to a sludge concentrated pool, after being concentrated then dehydrated by the plate-and-frame press filter
machine, finally the sludge cakes are transported to the outside. The system is stable in efficiency, strong in
shock resistance load ability.
