高效内循环生物反应器处理脱墨废水动力学特性初步研究

Kinetics Characteristics in the Treatment of Deinking Effluent with High Performance Inner-Loop Bioreactor

研究了脱墨废水用高效内循环生物反应器处理时的生物降解和生物增长动力学特征,求出了脱墨废水经两种不同预处理后的降解动力学方程及稳态条件下活性污泥的产率系数.与传统活性污泥法相比,其污泥的产率系数只有1/3～1/2.

Biodegradation kinetics and microorganism growth kinetics in the treatment of deinking effluent with high performance inner-loop bioreactor were investigated in this study. The degradation kinetics equations for pretreated deinking effluent with two ways were derived and yield coefficient of activated sludge in stable conditions was obtained. The yield coefficient of the activated sludge was only 1/3 - 1/2 of that of conditional active sludge process.
