摘　　要：采用活性炭填充高发泡(乙烯/乙酸乙烯酯)共聚物(E/VAC),制备了新型悬浮填料,用作污水处理中为微生物提供附着生长的载体。研究表明,当双螺杆挤出温度为185℃、过氧化二异丙苯质量分数为1%、偶氮二甲酰胺质量分数为1.5%时,E/VAC的密度和空隙率分别达到0.85g/cm3和60%。在复合式生物反应器中处理模拟生活污水,化学需氧量(COD)去除率为90%～95%,氨氮的去除率在75%以上。A new kind of suspended filler which can provide cartier for microorganism to congregate and grow in sewage disposal is prepared from high foaming E/VAC filled with active carbon. The results show that the density reach 0.85 g/cm^3 and void ratio reach 60% when extrusion temperature is 185℃, mass percent of cross-linking agent DCP is 1% and foaming agent AC is 1.5%. The removal ratios of COD and NH4 -N are 90% -95% and above 75% respectively when high foaming E/VAC carriers are used to treat the simulative sanitary sewage in Hybrid Biologyical Reactor.
