To calculate amounts of generated polychlorinated dibenzo-P-dioxins （PCDD）, polychlorinated dibenzofurans （PCDF）, chlorobenzenes, halocarbons and polynuclear aromatic hydrocarbons, ash and gas produced from the refuse incinerator's electrostatic precipitator （EP）and cooling tower were analyzed. These results showed chlorinated compounds remarkably increased in the EP. To study the chlorination process, experiments were performed. A large amount of chloroform, carbontetrachloride, trichloroethylene, tetrachloroethylene, 3～6 chlorobenzenes were obtained by treating the ash with HCl and then heating it at 300℃ in the presence of O2. Chlorination reactions were found to be accelerated by increasing coronadischage current, temperature, reaction time and concentration of HCl in annex perimental EP.
