摘　　要：采用粉末活性炭(PAC)与超滤膜(UF)相结合,经微生物的富集形成生物粉末活性炭-超滤(BPAC-UF)系统,以天津工业大学畔湖水模拟饮用水水源,考察了该工艺运行过程中对有机物及氨氮、硝氮和亚硝氮的去除效果。结果表明,投加PAC初期系统对有机物及氨氮的去除主要依靠活性炭的吸附及膜的截留作用。活性炭吸附饱和后,CODMn去除率逐渐降低,而氨氮的处理效果较差。系统运行30天左右,接触区形成生物粉末活性炭后,生物量明显增加,PAC基本转化成BPAC,系统对CODMn和氨氮的处理效果明显增加,其去除率分别达到75%和65%。Combined with PAC and UF, the BPAC-UF system was established by microbial accumulation. Taking Panhu Lake water of Tianjin Polytechnic University as water source of simulated drinking water, the removal effect of this process on organics, NH3-N, NO3^- -N and NO2^- -N was studied. The results indicated that the removal of organics and ammonia nitrogen by system was mainly depended on adsorption of activated carbon and membrane interception in the initial dosing of PAC. The removal rate of CODMn and ammonia nitrogen was decreased gradually with the saturation of activated carbon adsorption. The biomass was increased obviously, PAC was transformed BPAC totally and the removal effect of CODMn and ammonia nitrogen was increased sharply when the system was operated about 30 days and BPAC was formed in contacting area. The removal rates of CODM. and NH3-N were 75% and 65% respectively.
