Antibiotic wastewater with high refractory and toxic Organic compounds is high cost and difficult to be treated by traditional biotreatment technology. The effective of traditional treatment technology also did not match the discharged standard. The low removal rate and effective is still important question in this field. Therefore. more attention should have been focused on the novel and cost-effective treatment technology.This experiment was conducted in the centre of three waste treatments in North China Pharmaceutical Company Ltd. First, the reason and question of the existed engineering was analyzed. Then the high effective micoorgannism with A/O biological treatment technology was studied in details. Last engineering was designed in light of the experiment and conducted to study the effect of the new technology. The results of lab scale and pilot scale experiments showed that the high effective micoorgannism with A/O biological treatment technology have high removal rate of COD、NH3-N and meeted to the decharged standard. The new construted aerobic bank of 1 5000 m3 was performed at the following inlet parameters:6 000~7000 m3·d-1, in 10 000~20 000 mg·L-1 COD, in 500~1 000 mg·L-1 NH3-N, pH of 8; and the outlet effective was 200~400 mg·L-1 COD and 10~20 mg·L-1 NH3-N. The removal rate of COD and NH3-N was 95~98% and 98~99%, respectively.Therefore, the high effective micoorgannism with A/O biological technology was very effectivly for the antibiotic wastewater treatment of the centre of three waste treatments in North China Pharmaceutical Company Ltd, and the designed engineering based on the new technology might match with the decharged standard and has the practical application and knowledge values for the similar engineering or wastewater.
