中文摘要:
      使用20kHz和25kHz双频超声破解污泥装置,根据污泥滤液COD、NH3-N、TP的增量研究复频超声破解污泥的效果,并且详细探讨了影响复频超声破解污泥的影响因素(不同频率组合、不同作用方式、不同功率组合、不同时间组合).实验结果表明双频超声更有利于污泥破解,为污泥破解方法的应用和今后进一步扩大其研究提供一定的基础.
英文摘要:
      A 20 kHz and 25 kHz ultrasonic device has been developed and used to study the effect of dual-frequency ultrasound on sludge disintegration by changing COD,NH3-N,TP in filtrate.Effect factors including different frequency combination,different function mode,different power combination and different time combination of dual-frequency ultrasound have been discussed in detail.It has been indicated that dual-frequency ultrasound is more efficient to sludge disintegration.This study provide a basis for the application and the further study of sludge disintegration methods.
