| 摘 要： | 介绍了向曝气池中投加悬浮填料以改善曝气池的处理效能的试验研究。研究结果表明，投加悬浮填料可以降低曝气池的污泥负荷，提高活性污泥法的处理效率，改善活性污泥的沉淀性能。试验用悬浮填料能大大提高曝气设备的充氧能力，而且该填料挂膜块，膜厚适宜，易于流化，投加和更换方便，是一种极优的生物填料。

| Abstract: | Because the microbe could be increased and the sludge load could be decreased by putting media into the aeration tanks,the treatment ability and effect of aeration tanks could be improved and reduce the absolute value of water quality in effluent.The process could also improve the settling properties of activated sludge.The suspended media used in our research can improve greatly oxygenation capacity of aeration devices.The medium,which is easy to fluidize and grow biofilm under normal aeration intensity,and convient to put and change the number,is a superior kind of medium. |
