Chemical pre-treatment of synthetic Procaine Penicillin G (PPG) effluent with ozone (applied dose = 1440 mg/h; treatment duration = 60 min) at pH = 7 was investigated. Successive biological treatability studies were performed with raw, ozonated penicillin formulation effluent and synthetic readily biodegradable substrate as simulated domestic wastewater. The PPG effluent additions were adjusted to constitute approximately 30% of the total COD in the reactor. Ozonation of PPG effluent resulted in practically complete removal of the parent pollutant accompanied by 40% COD abatement. Speaking for the raw PPG effluent, prolonged acclimation periods were necessary to obtain significant COD removal efficiencies. Batch activated sludge treatment experiments and respirometric studies have demonstrated that the selection of true retention time is extremely crucial for having high amount of slowly hydrolysable substrate or complex wastewater, like pharmaceutical effluent. The effect of ozonation time on biological treatability performance of PPG has been evaluated in the study. Pre-ozonation of PPG effluent did not improve its ultimate biodegradability.
研究了在pH = 7的条件下，用臭氧对合成普鲁卡因青霉素G（PPG）废水进行化学预处理（施加剂量 = 1440 mg/h；处理时间 = 60分钟）。以原青霉素制剂废水、经臭氧处理的青霉素制剂废水和合成的易生物降解底物作为模拟生活污水，相继进行了生物可处理性研究。调整PPG废水的添加量，使其占反应器中总化学需氧量（COD）的约30%。PPG废水的臭氧化处理几乎完全去除了母体污染物，同时化学需氧量减少了40%。对于原PPG废水而言，需要较长的驯化期才能获得显著的化学需氧量去除效率。批次活性污泥处理实验和呼吸测定研究表明，对于含有大量缓慢水解底物或复杂废水（如制药废水）的情况，选择真正的停留时间至关重要。该研究评估了臭氧化时间对PPG生物可处理性性能的影响。PPG废水的预臭氧化处理并未提高其最终生物降解性。
