【摘要】 对高浓度难降解有机工业废水两类主要处理工艺的最新进展进行了综述和评价,一种是采用化学氧化和催化氧化为主的工艺;另一种是先预处理改变BOD/COD比值,然后再采用生化法处理工艺。经过分析,根据大多数高浓度难降解有机工业废水的特点,指出对“物化(混凝)-兼氧/缺氧/厌氧-好氧”工艺的各个环节进行研究是未来1～5a高浓度难降解有机工业废水处理技术的发展方向。并进一步指出针对高浓度难降解有机工业废水的专用混凝设备这一研究较少的领域,研制经济实用的强化混凝设备,将会成为适合我国国情的高浓度难降解有机工业废水处理技术的重要发展方向之一。更多还原

【Abstract】 There are two types of processes to treat the organic industrial wastew ater with high concentration and low biodegradability. One is using chemical oxi dation and catalytic oxidation as the main treatment process, and the other is u sing pretreatment methods to increase the biodegradability. Then biodegradation is used as the main treatment process. It is pointed that researches on the trea tment processes of "physicochemical (coagulation)-facultative aerobic/anoxic/a naerobic-aerobic technologies" are the practical developing directions of orga nic industrial wastewater treatment in the future 1-5 years. Based on this, It is pointed out further that researches on the specific coagualting equipment fo r this kind of industrial wastewater are rather few, therefore developing enhanc ed, practical and economic coagulating equipment will be one of the important di rections in this field.更多还原
