摘　　要：通过实验室小试,开展了前置生物活性炭工艺(PBAC)和常规生物活性炭工艺(CBAC)与砂滤联用时对浊度、氨氮、COD_(Mn)、UV_(254)、BDOC等污染物指标的去除效果,以及活性炭表面生物量、微生物多样性、群落结构、出水菌落总数等指标异同性的研究。相较于CBAC工艺,PBAC工艺与砂滤联用时对氨氮、COD_(Mn)、BDOC的去除率分别提高了5.79%、5.04%、16.07%,对浊度和UV_(254)的去除率相近,出水菌落总数下降了53.82%。PBAC工艺活性炭表面微生物量提高了31.11%,且其群落结构特异性显著,所具有的优势菌种较好地发挥了对有机物的降解作用,说明PBAC工艺在保障饮用水化学安全性与生物稳定性方面具有较好的效果。The similarities and differences in the removal of turbidity,ammonia nitrogen,COD_(Mn),UV_(254),BDOC and other pollutants,as well as the surface biomass of activated carbon,microbial diversity,community structure,and the total number of bacteria in the corresponding effluent were investigated by combining the pre‑BAC process(PBAC)and the conventional BAC process(CBAC)with sand filtration in a small‑scale test.Compared to the CBAC process,when PBAC was combined with sand filtration,the removal rates of ammonia nitrogen,COD_(Mn) and BDOC were increased by 5.79%,5.04%and 16.07%,respectively,and the removal rates of turbidity and UV_(254) were similar.The total number of bacteria in thev effluent decreased by 53.82%when the PBAC process was combined with sand filtration.Compared with the CBAC process,the biomass of the PBAC increased by 31.11%.The specificity of the community structure was significant,and the dominant species played a better role in the degradation of organic matter,indicating that the PBAC process had a better effect in ensuring the chemical safety and biological stability of drinking water.
