The Optimization and Test Study on UASB+AF Anaerobic Reactors

摘要: 该文首先建立升流式厌氧污泥床过滤器 (UASB +AF)的流形分布模型 ,在此基础上推导了UASB +AF反应器的动力学方程式。从中可知 ,反应器运行情况和截面积无关 ,反应器的最佳优化高度为 4 5～ 6m。试验结果证明 ,在UASB +AF反应器的悬浮层内安装组合填料构成的新型UASB +AF反应器 ,稳定运行容积COD负荷可达 1 0～ 1 2kg/(m3·d) ,COD去除率为 80 %左右。更多还原

Abstract: Based on the fluid flow of UASB+AF reactors, a kinetic model of UASB+AF reactors was set up. It was found that the area of the reactors had no influence on the operation, and the optimum height of the reactors was 4.5 to 6 m. The new type of reactors has installed combined fillings in the superposed layer of UASB+AF reactors. The results demonstrated that UASB+AF reactors have good effect and their COD volume loading is 10～12 kg/(m 3·d), and the removal of COD is about 80%. 更多还原
