中文摘要：
以高软化点沥青为原料,采用自发泡法制备泡沫炭,将其用作生物污水处理固菌载体材料,并通过添加适量的酚醛树脂以提高泡沫炭的开孔率,进而提高其生物挂膜量。研究结果表明：当在高软化点沥青中添加酚醛树脂的质量分数为30%时,所制泡沫炭的开孔率高达100%,生物挂膜量（质量分数）达5.4%;当酚醛树脂的添加质量分数为40%时,所制泡沫炭的压缩强度达5.2MPa,但其开孔率较低,孔结构的均一性较差。
英文摘要：
Carbon foams were synthesized by self-foaming method derived from high softening point pitch as packing media in biological aerated filter system. To achieve a high biofilm biomass,pwas added into the high softening point pitch to improve the open porosity of carbon foam. When the additive mass fraction of phenolic resin is 30% , the open porosity and mass fraction of biofilm biomass of the resultant carbon foam are 100% and 5. 4 % , respectively. When the additive mass fraction of phenolic resin is 40% , t he carbon foam has a high compressive strength of 5. 2 MPa accompanied with a low open porosity and a poor uniformity of pore structure.
