| 摘 要： | 探讨了低温条件下曝气生物滤池对城市污水二级处理的挂膜启动方法。根据近年来国内外的曝气生物滤池挂膜研究进展,结合活性污泥接种法和自然挂膜法的特点,采用了活性污泥接种闷曝后逐渐增加流量到设计流量的复合挂膜法,并以氨氮去除率稳定作为滤池启动成功的标志。试验结果表明,低温条件虽延长了曝气生物滤池的挂膜启动时间,但不影响挂膜质量,27 d后挂膜启动完成,此时浊度、COD和氨氮的去除率分别稳定在92%、70%、97%,出水水质良好且稳定,且对滤池短暂关闭后通入常规负荷污水的方式可在短时间重新启动。

| Abstract: | This experiment discussed the start-up method of biological aerated filter(BAF) in the test of secondary treatment of municipal sewage in low temperature.Combined with the characteristics of inoculation start-up and natural start-up,this paper suggested a start-up method that the filter filled with municipal sewage was added with activated sludge,and oxygen was supplied by the air compressor,and then the effluent were fed to the BAF with incremental flow rate of feed water until the media of BAF were covere... |
