Phenol and chlorophenols (CPs) are main toxic organic pollutants detected generally in source water. In the present studies, removal efficiency of phenol and CPs by using PAC adsorption was investigated, base on the control of drinking water sudden pollution. The results showed that the removal of phenol and CPs was essentially complete within 2 hours, and that the adsorption ratio in proper order was: 2, 4, 6- TCP > 2, 4- DCP > 2- MCP > PCP > phenol. The adsorption isotherm of phenol and CPs by PAC was consistent with the Freundlich and Langmuir adsorption mode. The study on the raw water collected from a lake in a university also provided the evidence that water quality affected the adsorption rate and adsorption capacity apparently. The phenol and CPs in sudden water pollution accidents was removed by addition of 20mgL-1 PAC. Results provided technical solution for water pollution accidents to cope with phenol and CPs sudden.
