title: [Comparative study on the organic matter removal in polluted raw water by different techniques at integrated pilot plant].
abstract: The traditional technique, preozonation technique, granular activated carbon adsorption technique and ozone-biological activated carbon technique were compared on its removal efficiency of organic matter and the THMs formation potential (THMFP) as well. It was found that, as compared with the former two techniques, the last two were more effective in organic matter removal, and the efficiency reached 75% - 90%, while the former only at 50% - 60%. The waterworks that adopted the Grade II source raw water were suggested to use the conventional techniques and seasonal preozonation techniques, while the others were suggested to alternatively select GAC or BAC technique to meet the request of new water quality criterion.
