摘　　要：采用中置O3-BAC工艺进行中试实验,通过对微生物、微型生物、消毒副产物和AOC进行检测分析,研究了不同的消毒方式对砂滤池出水消毒效果的影响。结果表明,氯消毒对微型生物、微生物的去除效果稍弱于臭氧联合氯消毒;对于消毒副产物而言,氯消毒产生的卤代烃、氯酸盐的含量高于臭氧联合氯消毒,产生的溴酸盐两者处于同一水平,而产生的甲醛则是氯消毒低于臭氧联合氯消毒;氯消毒最终砂滤池出水AOC平均含量75.93μg乙酸碳/L,臭氧联合氯消毒为101.23μg乙酸碳/L,大于100μg乙酸碳/L,不利于供水管网的生物稳定性。Using pilot test with the mid-positioning O3-biological activated carbon filter, influences of different disinfection methods on disinfection efficiency of outlet water from sand filter were researched by the detection and analysis of microorganism, micro aquatic animals, DBPs and AOC. The results showed that the effect of chlorine disinfection was slightly weaker than ozone disinfection combined chlorination in removing microorganisms and micro aquatic animals. For the disinfection by-production of halogenated hydrocarbon and chlorate, chlorine disinfection produced more than ozone disinfection combined chlorination, the bromated is on the same level, while the formaldehyde is the opposite. The average AOC of sand filter effluent with chlorination and with ozone disinfection combined chlorination is 75.93 μg acetic acid carbon/L and 101.23 μg acetic acid carbon/L, respectively. The latter is more than 100 μg acetic acid carbon/L, which is unbeneficial for the biology stability of water distribution system.
