国内柠檬酸废水处理方法研究进展

Research Progress on Domestic Citric Acid Wastewater Treatment

中国是世界上最大的柠檬酸生产和出口国,但柠檬酸生产工艺的固有特点使其生产过程中产生大量高浓度废水,对环境造成严重污染。文章对我国柠檬酸废水处理的方法进行了综述,着重介绍了近几年发展起来的几种柠檬酸废水处理的方法如厌氧生物法、好氧生物法、厌氧-好氧组合法、厌氧-兼氧-好氧组合法、光合细菌法、乳状液膜法、微波辐射二氧化锰处理法、Fenton试剂法等,对不同处理方法的原理和工艺流程做了比较。

China is the largest country of citric acid production and exportation, but the fixed characteristics of citric production technology produces amounts of highly concentrated wastewater in the process, which leads to a serious environmental pollution. Several wastewater treatment technologies of citric acid in recent years, including anaerobic treatment, aerobic treatment, anaerobic-aerobic treatment, anaerobic-facultative anaerobic -aerobic treatment, photosynthetic bacteria method, emulsion liquid membrane, microwave radiation by MnO2 and Femon＇s reagent method were presented. In addition, comparison of the principles and process routes between different technologies were presented.
