In 1968 extensive research on direct potable reuse was conducted in Windhoek, Namibia.
自1960年以来,迫于调整压力和水的缺乏,一份深入的调查结果给水再利用工程的健康风险和治疗系统提供了有价值的洞察力。1965年,以色列健康部门出版章程允许对农作物灌溉实行二次污水再利用,还有被排除在外的不用煮可以吃的蔬菜作物。1968年在温得和克和纳米比亚对直接可饮用的再利用进行了广泛的研究。1972年在美国,有一件重要事件就是通过了联邦水污染控制法案(PL92-500)&修复并且维持民族水资源的化学,物理和生物的完整性。&

In this paper, the control factors of anaerobic digestion are discussed based on the summarization of present research literatures. The mechanism of the effect of pH and Eh on anaerobic digestion is analyzed with microbiology and biochemistry theory. The equation describing the effect of pH variation on Gibbs free energy variationΔGis derived using Nernst equation, and the specific control conditions in engineering are summed up according to the present research achievements.
在总结已有文献的基础上,讨论厌氧消化过程的控制因素,并利用微生物学和生物化学理论分析了pH值和Eh对厌氧消化过程影响的机理;利用Nernst方程推导出了描述pH值变化对吉布斯自由能变化ΔG的影响的方程式;并结合已有的研究成果,总结了实际工程中的具体控制条件。
