摘　　要：采用合适的挂膜方法能够加速好气滤池的启动,并能使其稳定运行.通过试验对3种挂膜方法进行了比较,对各种挂膜方法下滤料上的生物量和生物活性及滤柱对有机物和氨氮等指标的去除情况进行了测定和分析.结果表明,逐渐增加进水流量的挂膜方法可以加快好气滤池的启动,8d后溶解性COD的去除率稳定在36%左右,启动时间明显少于直接采用设计流量进水的挂膜方法;利用二级处理的回流污泥进行接种对好气滤池的启动没有加速作用,相反,还会延迟启动时间.Three start-up methods are compared and the biomass attached to filter media and its biological performances during the aerobic start-up are analysed. In comparison with the start-up with nominal process flow-rate, the start-up with incremental flowrate can accelerate the microorganisms accumulation in the aerated filters, and shorten the start-up time. In the eight days from the start-up, the removal rate of soluble chemical oxygen stayed at 36 percent. Seeding activated sludge from a secondary treatment pant can not help start-up, and on the contrary, it may delay a start-up.
