Abstract Tetrachloroethylene (PCE) is one of the commonly found organic pollutants in groundwater. After entering and accumulating in aquifer, the pollutant is difficult to dissolve, move and desorb from media, resulting in incomplete repair, rebound effects and some other remedial problems. In this study, surfactant colloidal gas aphron (CGA) flushing technology was used to increase the solubility and the mobility of PCE in aquifer, by which the transport flux of the pollutant could be increased and the remedial effect could be enhanced. The main parameters and influencing factors on CGA stability showed that the stirring speed of 4000r/min could produce stable CGA. The stability increased slightly with the increase of surfactant concentration, and PCE had an adverse effect on it. Besides, the migration of CGA in aquifer showed that the migration front of foam burst continuously during the migration process, causing the separation of the gas and the liquid in the front migration part. The gas migrated in the upper part with the liquid in the lower part in the front area of foam, and the subsequent stable foam pushed them forward. The pressure on foam in aquifer was greater than that in soil, resulting in the foam bursted more severely and the rate of migration got slower. In addition, compared with liquid, the flushing of foam had better effects on enhancing the solubility and mobility of PCE. When the media sizes were 0.1~0.25mm, 0.25~0.5mm and 0.5~1mm, the corresponding removal rate of PCE was 83.7%, 90.8% and 98.2% respectively, and the larger the media sizes, the more obvious the removal effect.
