摘　　要：利用生物活性炭／超滤（BAC／UF）工艺替代砂滤，将传统饮用水处理工艺改造成以BAC／UF为核心的短流程深度处理工艺。通过测定跨膜压差、有机物和颗粒物等指标，研究了深度处理工艺的效果。结果表明，改造后的深度处理工艺出水浊度〈0．1NTU，大于2μm的颗粒数均值为46个／mL，微生物安全性显著提高。出水CODMn平均为0．81mg／L，比改造前降低了15％。通过强化反冲洗工艺可将跨膜压差控制在40～50kPa之间。经改造后工艺运行成本由0．226元／m^3增加至0．366元／m^3，增加了约0．14元／m^3。BAC／UF替代传统砂滤显著提高了饮用水水质，经济可行，具有椎广应豫潜力。The traditional sand filtration was replaced by biological activated carbon/uhrafiltration （BAC/UF） to form a short process for advanced drinking water treatment. The parameters of trans-membrane pressure（TMP）, organic matter and particular matter were used to investigate the performance of the advanced treatment process. The results showed that the effluent turbidity was lower than 0.1 NTU and the average amount of particular matter larger than 2 μm was 46 particles/mL, indicating high microbial safety of drinking water. The average concentration of CODM. in the effluent was 0.81 rag/L, which reduced by 15% compared with that in traditional process. The TMP was controlled between 40 to 50 kPa through enhancing back washing process. The operation cost of the advanced treatment process increased from 0. 226 Yuan/m^3 to 0. 366 Yuan/m^3. The replacement ter treatment greatly improved the water quality. In addition tion can promote the upgrading of drinking water treatment of sand filtration by BAC/UF in drinking wathe process is cost-effective and its applicaplants with traditional process.
