【摘要】 针对山梨酸生产废水研究经济、高效和稳定的生化处理工艺是本文的出发点，在诸多的反应器中选取结构简单、处理效能高等特点的厌氧折流板反应器为载体，研究厌氧折流板反应器处理山梨酸生产废水的效能、基质降解动力学和所形成颗粒污泥的特性分析。本次ABR试验的运行经历了三种不同污泥负荷率：0.54、0.76、1.63kgCOD／(kgVSS·d)，在这三种不同污泥负荷率下，COD去除率分别达到了78～85％、66～76％和44～55％。从ABR处理山梨酸生产废水处理效果来看，对于含有难生物降解物质较多的山梨酸生产废水，较短的停留时间难以达到理想的处理效果，水力停留时间延长，处理效果明显增加，这是由于厌氧微生物充分对有机物进行分解的缘故。但当水力停留时间延长至72小时，COD去除率虽有增加，而增长速率明显趋缓，说明此时废水中易降解的有机物质大部分已经被去除，而剩余的难生物降解物质的降解难度较大，需要更长的时间才能对其进行有效的降解。从不同隔室对COD去除率的贡献来看，不同的污泥负荷下，第一、二和三隔室变化不大，但随着污泥负荷的增加，第四隔室COD去除率贡献变化明显，由8％增至22％。本文选用悬浮生长模型对ABR进行动力学推导，并根据山梨酸生产废水的特性选择了Andrews基质去除抑制动力学模型，然后通过三组不同水力停留时间的试验数据推导求出了三组不同更多还原

【Abstract】 This paper bases on the point of researching and developing wastewater anaerobic treatment technologies and processes with the traits of low cost, high capacity, stability and flexibility to treat chemical wastewater as sorbic acid. Anaerobic baffled reactor(ABR) is selected from numerous anaerobic reactors owing to its advantages of simple structure, as well as high removal efficiency. In this study, lab-scale experiments were conducted in a continuous-flow ABR to investigate removal efficiency of high organic concentration sorbic acid wastewater treatment,kinetics of substrate biodegradation and the characteristics of granular sludge. The experiment is conducted under three different sludge loading rate of 0.54,0.76 and 1.63 kgCOD/(kgVSS·d) with chemical oxygen demand removal eifficiency achievement of 78～85%、 66～76% and 44～55% respectively. The experiment results shows that high removal efficiency can not achieve in short hydraulic retention times treating sorbic acid wastewater containing hard biodegradation substrate with ABR.As hydraulic retention times prolonged,high removal efficiency achieves. The COD removal efficiency keeps increasing while hydraulic retention times prolongs to 72hours,but the increasing tendency obviously slows down. This phenomenon indicates that the most part of easy biodegradation substrate is completely biodegraded and more hydraulic retention times is necessary in order to biodegrade the hard biodegradation substrate. From the point of COD removal contribution, the three front compartments almost keeps stable under different sludge loading更多还原
