The invention relates to a treatment method of wastewater produced by cephalo synthetic drug manufacturing, which mainly comprises three parts, namely, aerobe catalytic oxidation, anoxia hydrolytic acidification and a membrane biological reactor; firstly, organic matters having better biodegradability in the wastewater are removed in a biological contact oxidation pond, then biological hydrolytic acidification is carried out in an anoxic pond, and then the wastewater flows into the membrane biological reactor to carry out final aerobic Bioremediation; the wastewater after the treatment passes through an ultrafiltration membrane in the membrane biological reactor and is pumped out by a pump and then discharged to an effluent pipe after reaching standards or recycled to the production technology; the membrane biological reactor consists of an aeration zone and a membrane filtering zone, wherein, the aeration zone carries out aeration by adopting a disc-shaped millipore aeration head, the ultrafiltration membrane is positioned in the membrane filtering zone, the organic matters in the wastewater after being treated with aerobe contact oxidation and anoxia hydrolytic acidification are basically biodegraded, the wastewater is pumped out through the ultrafiltration membrane, and microbes in the reactor are blocked in the reactor. The method has the advantages of simple technique, good effect of treating wastewater, small occupation area, and low treatment cost, and is especially suitable for the wastewater produced by the cephalo synthetic drug manufacturing.
