摘　　要：医院污水不同于普通的生活污水,不仅水质水量波动大且污水中含有大量杀菌剂,采用纯氧曝气—变速生物滤池组合工艺处理医院污水,有利于活性污泥的培养和驯化。系统的启动调试及活性污泥培养驯化历时一个月左右,活性污泥絮体基本形成,生物相基本稳定,处理效果显著,出水各项指标达标,成功完成了该污水处理站的启动调试。Unlike the domestic sewage, the hospital wastewater not only fluctuates greatly in quality and quantity but also contains quantities of antiseptic. Employment of the combination process of pure oxygen aeration and variable velocity bio-filter in hospital wastewater treatment will be beneficial to cultivation and domestication of activated sludge. After a month of system starting up, commissioning operation, activated sludge cultivation and domestication, the activated sludge floc had formed, the biological pattern was stable, treatment effects were obvious and every index met the requirement, which means the starting up and commissioning operation was completed successfully.
