摘要
随着化学工业及其相关产业的高速发展,高浓度有机废水日益增多,对人类健康的威胁加剧,其新型适用的处理技术研发具有迫切性和必要性.对目前国内外高浓度有机废水的处理技术进行了综述,系统归纳出处理高浓度有机废水的方法,即物理化学方法、生物学方法及其组合方法,并阐明了各种方法的技术原理.就现有高浓度有机废水处理工艺技术而言,处理工艺具有彻底矿化降解污染物、二次污染风险低等优点,但也存在工艺流程复杂,运行费用高等不足.最后,提出高浓度有机废水处理技术的研究重点,为进一步的研究指明了方向.
With the high-speed development of chemical industry and related industries,the quantity of high concentration organic wastewater is gradually growing followed by intensified threat to human being＇s health. So the research on its new applicable process technology becomes urgent and necessary. The treat- raent techniques as well as treatment methods of high concentration organic wastewater both at home and abroad were summarized, and these methods include physical and chemical method, biological treatment method and combined method. Principles of these methods were explained. For present wastewater treatment technologies,they have many advantages, such as completely mineralization for degradation of poUutants, and low risk of secondary pollution. But there are also some shortcomings like complex process and higher operation cost. Finally the focus of research which should be two phase combined technology was proposed, which pointed out the direction of the research for further experiments.
