摘要：
Anaerobic digestion (AD) is an important technology for the resource utilization of organic wastes. However, the fluctuations in the waste characteristics and operating parameters during the actual engineering operation might cause the accumulation of volatile fatty acid (VFAs), thereupon, resulting in the depression of biogas production and even the failure of AD due to over acidification. Based on the review of research progress both at home and abroad, this study describes the mischiefs of VFAs accumulation briefly, dissects the major causes of acid accumulation, and summarizes the counter measures from the two aspects of early-warning monitoring and regulation means required before and after acidification, respectively. Hereon, the authors suggest further strengthening the perfection of early-warning index system for the acidification during AD process, breaking through the bottlenecks of acclimation technology to obtain environment-tolerant type microbial flora, and researching the method based on endogenous acid-alkaline buffering system to reinforce the shock resistance of the AD reactor, attempting to provide some reference for enhancing the efficiency and stability of AD reactors in practice. © 2023 Chemical Industry Press.
