| 摘 要： | 以长江下游镇江征润洲段为原水,利用中试装置研究臭氧-生物活性炭(O3-BAC)组合工艺优化运行及其对有机物特性变化的影响。结果表明:当调整主臭氧投加量为2.5 mg/L时,深度处理工艺对CODMn、NH4^+-N和两类消毒副产物前体物(TTHMFP、THAAFP)的去除率分别为68.5%、86.7%、57.3%和48.9%;同时,从净水过程中有机物特性变化对消毒副产物影响的角度,提出应将强疏水性小分子有机物作为镇江市饮用水处理的控制主体。

| Abstract: | Raw Water is intaken from Zhenjiang Zhengrunzhou section in lower reaches of the Yangtze River.A pilot plant was used to study the optimized operation of ozone-biological activated carbon(O3-BAC)combined process and its effect on the changes of organic characteristics.When main ozone dosage was 2.5 mg/L,removal efficiency of CODMn,NH4^+-N,TTHMFP and THAAFP were 68.5%,86.7%,57.3% and 48.9%.Small hydrophobic organic molecules should be used as the control body for drinking water treatment in Zhenjiang City from the perspective of the effects of changes in the characteristics of organic matter on the disinfection by-products in the process of water purification. |
