摘　　要：进入城市污水处理厂的污水往往含有大量的工业废水,由于其难生化降解性,采用传统的A/O工艺难以确保达标排放。研究结果表明:以粉末化硅藻土作为生物载体强化A/O工艺,该载体可载持更大的生物量,从而提高系统的处理效率和抗冲击负荷能力。该体系值得进一步研究并可能成为未来工业废水处理的基本单元。Effluent flowing into the municipal sewage treating plant usually contains vast quantity of industrial wasterwater which is hard to be degraded by traditional A/O process due to its non-biodegradability. In this paper, the enhanced A/O process using powdered diatomite as biological carrier was studied.The results showed that the carrier could support more microorganisms, resulting in increased treatment efficiency and enhanced capacity of anti-impact load. The apparent enhancement achieved by the use of the biological carrier makes this system worthy of fuether study. Ultimately, it may form the basis of important techniques for treating industrial wastewater.
