摘要
采用加压活性炭生物膜法处理以对硝基甲苯磺酸盐为主的难降解的有机废水的研究,是在活性炭生物膜法处理有机废水基础上发展起来的新技术。本实验结果表明,在加压9.8×10~4Pa(1kgt/cm^2)的条件下,COD_(Cr)去除率为62％～70％,比常压活性炭生物膜法高20％～25％;其容积负荷Nv=1.7～2.9kgCOD/m^3·d,比一般活性污泥法高3～6倍。
Wastewater containing soduim p-nitrotoluenesulfonate could be treated by using pressurized activated carbon/biological membrane process. The result showed that COD removal could be 62-70%, 20-25% higher than the traditional activated carbon/biological membrane process and the volumetric loading Nu=1.7-2.8kg COD/m^3 day, was as 4-7 times value of traditional activated sludge process.
