According to the characteristics of the raw water of Xiangjiang River， the experiment on pollutant removal by the combined process of ozone （O3） and biological zeolite has been conducted. The results of the experiment aiming at the influent water quality show that before the biological film is formed， the highest removal rates of CODMn and ammonia-nitrogen reach 43.1% and 93.4%， respectively. After the film is matured， and when the ozone dosage is about 2.2 mg/L， oxidation contact time 15 min， and hydraulic load about 2.3 m/h， the removal rates of CODMn and ammonia-nitrogen by this process are 53.6% and 86.1% ， respectively.
Key words： slight pollution raw water; ozone; biological zeolite
