摘要
柠檬酸是一种重要的有机酸,其生产过程中产生大量高浓度有机废水,处理不当会对环境造成严重污染。文章介绍了柠檬酸生产废水的来源及水质特征,分析了国内对柠檬酸废水的主要处理方法,并对柠檬酸废水的厌氧处理进行综述。提出了对柠檬酸废水二级出水进行厌氧处理的方法,在实现污染控制目标的同时最大限度地回收沼气等能源物质,实现废物综合利用。
In the production of citric acid which is an important organic acid, amounts of highly concentrated wastewater which may cause serious pollution to the environment would be discharged. This paper introduces the source and characteristics of citric acid wastewater, analyzes the main methods of citric acid wastewater treatment, and summarizes the method of anaerobic treatment to citric acid wastewater. In addition the method of anaerobic treatment to the secondary effluent of citric acid wastewater is put forward, which could recover energy material such as biogas while realize the target of pollution controlling, leading the result of comprehensive utilization of wastewater.
