摘　　要：通过工艺Ⅰ（预臭氧＋常规处理＋后臭氧＋生物炭滤）和工艺Ⅱ（预臭氧＋常规处理＋生物炭滤）的对比试验，对属于Ⅱ～Ⅲ类地表水的广州市东江水源进行臭氧-生物活性炭（O3-BAC）深度净水中试，研究了污染物的去除规律，并对照南洲水厂的实际运行效果，提出了依据原水不同水质状况优化运行的建议．中试结果表明，当水源CODMn低于3．0mg／L及氨氮含量低于1．0mg／L时，可按工艺Ⅱ方式运行；当水源CODMn．高于3．5mg／L或氨氮含量高于1．5mg／L时，需要按工艺Ⅰ方式运行，以确保出水达到标准．南洲水厂运行结果也表明，可根据原水水质分别按照工艺Ⅰ或工艺Ⅱ方式优化运行．A pilot-scale experiment of O3-biological activated carbon （O3-BAC） advanced treatment process was carried out for the surface water at levels Ⅱ～Ⅲ in the Dongjiang River, Guangzhou. The removal rules of the contamination in the water were then investigated. In the experiment, two processes, namely Process Ⅰ-pre-ozone ＋ conventional treatment process ＋ O3 ＋ BAC and Process Ⅱ -pre-ozone ＋ conventional treatment process ＋ BAC were adopted to perform a contrast test. The experimental results were finally compared with the practical data of the Nanzhou Drinking-Water Treatment Plant. Some suggestions for the optimization of O3-BAC process were made in accordance with the quality of the raw water. The results of the pilot-scale experiment show that, in order to ensure the drinking-water quality, Process Ⅱ should be adopted when the raw water is of a CODMn of no more than 3. 0mg/L and a NH3-N content of no more than 1.0mg/L, and that Process Ⅰ should be adopted when the raw water is of a CODMn of more than 3.5 mg/L or a NH3-N content of more than 1.5 mg/L. The practical operation results of the Nanzhou Drinking-Water Treatment Plant also reveal that Processes Ⅰ and Ⅱ can be alternately adopted in accordance with the quality of the raw water.
