饮用水臭氧-生物活性炭工艺水质安全性述评

Discussion on Drinking Water Quality Safety of Ozone-biological Activated Carbon Process

从化学安全性和微生物安全性两方面论述了臭氧-生物活性炭(O3-BAC)工艺水质安全性。化学安全性方面,以微量有机物、各种消毒副产物和藻毒素为参考指标,探讨了O3-BAC工艺去除和控制饮用水中有机物的效果。针对微生物安全性问题,主要从病原微生物及其群落、浊度和颗粒数、可同化性有机碳(AOC)等方面进行阐述。通过大量文献分析表明:O3-BAC工艺对水中大部分有机物有良好的去除作用,可保证水质化学安全性;不同原水水质对O3-BAC工艺水质微生物安全性有重要影响。

The quality safety of drinking water of ozone and biological activated carbon （O3-BAC） process was introduced from chemical safety and microbial safety.The efficiency of O3-BAC process in removing and controlling organic compound were investigated from index of trace organic compounds,disinfection by-products and algal toxins in drinking water. In addition, the microbial safety of O3-BAC process was expounded from pathogenic microorganisms and its community,turbidity, particle number and AOC.The analysis shows that the quality of raw water has a good impact on the microbial safety of O3-BAC process ,which could guarantee the chemical safety of drinking water.
