摘　　要：研究了不同水处理组合工艺的除污染效能,包括化学预处理、常规处理、生物活性炭或臭氧生物活性炭技术的联用。试验结果表明,臭氧预氧化、高锰酸盐复合药剂(PPC)预氧化均能强化生物活性炭或臭氧生物活性炭工艺对各项指标的去除,可提高对浊度、UV254、CODMn的去除率;PPC预氧化与生物活性炭联用技术可强化AOC、BDOC的去除效果,达到生物稳定性的控制要求,是适合我国水厂改造的水处理技术。Purification efficiencies of different combined water treatment processes, including chemical pretreatment, conventional treatment, biological activated carbon （ BAC ） or ozonation biological activated carbon （O3/BAC） and their combination technology were compared in a waterworks. The results showed that preozonation and PPC pretreatment could improve the removal efficiencies of BAC or O3/BAC. The removal rates of turbidity, CODMn and UV254 could be increased respectively. Combined application of PPC pretreatment and BAC could enhance the removal of AOC and BDOC to fit the requirement of biological stability control. It indicated this process would be the best water treatment process for reconstruction of waterworks in China.
