摘要
研究了采用四级内循环好氧生物膜反应器串联工艺对悬浮法聚氯乙烯(SPVC)离心母液废水的处理效果。根据运行数据,得出各级反应器内基质降解动力学模型。结果表明,该废水中不可生物降解的基质浓度在20mg/L左右,分别测得各反应器内的饱和常数Ks为:439.7,146.2,43.36,15.43mg/L,单位面积填料基质最大去除速度Umax为72.92,20.79.7.22,4.18g/m2·h。
Mother liquid of susponded polyvinyl chloride (SPVC) was treated by 4 cascade aerobic biofilm reactors with internal circulation. Based on the experimental data, the mathematical model of organic biodegradation in each reactor was obtained. The results showed that the non-biodegradable substance concentration is about 20mg/L, the saturation constants Ks in each reactor are: 439. 7,146. 2,43. 36,15. 43mg/L and the maximum substance removal velocities Umax are 72. 92, 20. 79,7. 22,4. 18 g/(m2·h) respectively.
