Particulate pollution is main kind of atmospheric *** fine particles are seriously harmful to human health and *** agglomeration is considered as a promising pretreatment technology for fine particle *** mechanisms of acoustic agglomeration are very complex and the agglomeration efficiency is affected by many *** most important and controversial factor is *** studies between high-frequency and low-frequency sound source to agglomerate coal- fired fly ash were carried out to investigate the influence of frequency on agglomeration *** agglomeration theoretical analysis,experimental particle size distributions （PSDs） and orthogonal design were *** results showed that the 20 kHz high-frequency sound source was not suitable to agglomerate coal-fired fly *** within the size ranging from 0.2 to 0.25 μm the particles agglomerated to adhere together,and the agglomerated particles were smaller than 2.5 μ*** application of low-frequency （1000–1800 Hz） sound source was proved as an advisable pretreatment with the highest agglomeration efficiency of 75.3%,and all the number concentrations within the measuring range *** design L16 （4） 3 was introduced to determine the optimum frequency and optimize acoustic agglomeration *** to the results of orthogonal analysis,frequency was the dominant factor of coal-fired fly ash acoustic agglomeration and the optimum frequency was 1400 Hz.
