中文摘要：

用染色法和水听器法对实验所用处理槽中的声场进行测量，在此基础上分别研究了超声频率和双频复合、组合、单频方式对污泥滤波的COD、NH3-N、TP的影响．实验结果表明双频组合超声相对单频超声作用效果要好，单频超声作用时，低频效果较好，并对其原因进行了分析．

英文摘要：

Sound field of reactor has been measured by dyeing method and effect including ultrasound frequency, combination or compounder dual -frequency ultrasound, single frequency ultrasound by change of COD,NH3 -N,TP in the filtrate has been researched in the experiment of sullage disintegration. Effect of combination dual - frequency is better to single frequency ultrasound and effect of low frequency ultrasound is better to high frequency ultrasound and reason has been analyzed. Dual -frequency ultrasound vails yet sullage disintegration that is indicated, and defines foundation has been offered for application of method of sullage disintegration.
