摘　　要：主要研究超声处理后剩余污泥性质的变化,探讨了污泥上清液中SCOD、BOD、TN、TP以及污泥耗氧速率OUR等随超声时间和声能密度的变化,尤其是对进一步的污泥处理处置的影响进行分析。研究表明,超声处理后的污泥结合到污水处理工艺中可以实现污泥隐性生长而达到污泥减量的目的;或者为污泥进一步处理处置提供了有利条件。Experimental study on characteristic change of excess sludge after ultrasonic treatment is carried out.The SCOD,BOD,TN and TP in supernatant and OUR of sludge are changed with ultrasonic time and power levels.And the effect of this ultrasonication on sludge disposal is especially analysed.According to this study, either the sludge after ultrasonication is combined with the system of wastewater treatment to be as a new substrate for microbe,then the reduction of biomass will be achieved; or it will create the good condition for disposal of this sludge.
