The results of jar stirring test and the concen tration change of each organic compound detected by GC/MS analysis in source and after-treatment wastewater suggest that organic pollutants are mainly remove d by complex-sedimentation and floc-adsorption mechanisms. The removal rate of each organic pollutant is highly depending on its molecular structure. Generall y, organic pollutant having a strong ability to adsorb on hydroxide flocs or hav ing a complex function group without steric hindrance is easy to be removed.
