摘要
本文考察了三段式活性炭生物膜反应器对实际生活污水的处理效果,测定了第二段气、液、固三相反应器的流态,并对实际生活污水的基质去除动力学进行了研究。实验结果表明,该装置对实际生活污水有较好的处理效果,第二段反应器的流志接近平推流,实际生活污水的基质去除动力学为一级反应动力学,动力学常数范围为0.011～0.027min^(-1)。
A new fixed-film reactor with a three-stage bed was studied experimentally The operation parameters of the reactor for treating domestic sewage containing COD concentration up to 360 mg/L were investigated and a good result was obtained.The flow pattern in the three-phase portion of the reactor was determined by using tracer pulse input technique with Rhodamine-B dye.The kinetics of the substrate-removal in the reactor was studied.The results show that the first order reaction kinetics fits in with the substrate conversion.The reaction rate constants were in the range of 0.011 to 0.027
