摘　　要：在一体式膜生物反应器的生活污水处理工艺中,适量投入粉末活性炭(PAC)可有效提高系统产水水质,并可降低膜污染,减缓膜通量衰减.本试验在温度为21～26℃、pH值为7.0左右、DO在(3.0±0.5)mg/L条件下进行,测得:当PAC投加量在2～15g之间时,系统去除率随活性炭加入量的增加而增加,最大可达98.81%.在450mm水位差下出水,加入PAC的反应器的出水量比未加入PAC的出水量下降的慢,当PAC投入量为6g时,两者之差最大值达41.7mL/min.When domestic wastewater was treated with submerged membrane bio-reactor(MBR),adding properly PAC to the reactor,the water quality of effluent was effectively improved and the pollution of membrance was reduced.Meanwhile,the attenuation of membrane flux was slowed down.The test was carried out at 21～26 ℃,pH being about 7.0,and DO being about (3.0±0.5) mg/L.The results show that the removal efficiency of COD_(Cr) was increased with the increase of PAC while PAC was 2～15 g,and the highest removal efficiency was 98.81%.When there was 450 mm water-head,the amount of yielding water in the reactor added in PAC became slower than that added in no PAC.As PAC was 6 g,the maximum differential value between them is 41.7 mL/min.
