摘　　要：对黄浦江上游原水进行臭氧生物活性炭中试研究表明:在臭氧有效投量为2.0 mg/L、臭氧接触塔和活性炭柱停留时间均为11 m in的条件下,臭氧生物活性炭工艺对水中CODMn和UV254的平均去除率分别为29.95%和48.83%,出水CODMn和UV254值分别为2.96 mg/L和0.053cm-1;为保证炭柱出水氨氮浓度≤0.5 mg/L,建议控制炭柱进水氨氮浓度≤1.5 mg/L;水温、进水浓度、炭柱停留时间以及臭氧投量对污染物去除效果均有一定的影响。A pilot-scale research of ozone - biological activated carbon （ O3 - BAC ） was conducted for advanced treatment of polluted upper reaches raw water of Huangpu River. Under 2.0 mg/L of effective ozone dosage and 11 min of ozone tower contact time and empty bed contact time （EBCT）, the mean removal rates of 29.95% and 48.83% are obtained for CODMn and UV254 respectively while the effluent concentrations are 2.96 mg/L and 0. 053 cm^-1 for CODMn and UV254 respectively. The influent ammonia nitrogen concentration is suggested to be controlled within 1.5 mg/L in order to assure the effluent ammonia nitrogen concentration to be less than 0.5 mg/L. It is found that the impacting factors for pollutant removal consist of temperature, influent pollutants concentration, EBCT and ozone dosage.
