在废水污泥的厌氧消化中产生的有机酸倾向于连续地将pH值降低到低于酸可以转化为甲烷的点。因此，需要大的缓冲能力来保持pH在6.7和7.4之间，这允许有效的操作。目前测量这种缓冲能力的测试是不够的。本研究提出了一种简单但足够的测试，将为工厂操作员提供有关厌氧消化器效率的准确信息，以及对消化器操作的长期洞察-似乎可以常规使用pH值为5.75的碱量滴定法来监测实验室和实际厌氧消化器性能，具有高度的置信度。该测试的简单性应鼓励许多操作员更加关注消化器的性能，从而提高废水处理效率。（参考文献）7）。
Organic acids produced in the anaerobic digestion of waste-water sludges tend continuously to depress pH below a point where the acids can be converted to methane. As a result, a large buffering capacity is required to maintain pH between 6.7 and 7.4, which allows efficient operation. Present tests to measure this buffer capacity are inadequate. The present research proposes a simple but adequate test that will provide plant operators with accurate information on anaerobic digester efficiency, as well as considerable long-range insight into digester operation - it would seem that an alkalimetric titration to pH 5.75 can be used routinely to monitor laboratory and actual anaerobic digester performance with a high degree of confidence. The simplicity of the test should encourage many operators to pay more attention to digester performance and, therefore, result in improved waste water treatment efficiency. (Refs. 7).
