Fe-C MCWAO催化剂的催化活性研究

采用微波湿式催化氧化 (MCWAO) 技术,以活性艳红X-3B模拟废水处理对象,以Fe-C作为MCWAO催化剂,空气作为氧化剂,探讨MCWAO技术的可行性.研究表明,在MCWAO（常压下的微波曝气湿式催化氧化）过程中脱色率和COD去除率明显高于MCWO（常压下的微波不曝气湿式催化）、CWAO（常压下的水浴曝气湿式催化氧化）、CWO（常压下的水浴不曝气湿式催化）及MCWNO（常压下的微波曝氮气湿式催化）.实验结果表明Fe-C具有较高MCWAO催化活性,同时证实了空气此过程中起了重要的作用.     

非均相CWO法对难降解印染废水色度的去除

通过单因素实验和正交实验,研究了采用Cu-Fe-La/FSC催化剂的CWO法处理印染废水影响因素,以及优化操作条件下的水样可生化性.结果表明:水样脱色率随催化剂用量、反应温度、反应总压的增加和反应时间的延长而提高,随进水浓度的升高而降低;各因素对水样处理的影响为:反应温度>反应时间>催化剂用量>反应总压>进水浓度;CW...     

Research on Treatment Technology for the Industrial Wastewaters with High Concentration in China

1 IntroductionWiththe high-speed development of Chinese economy,allkinds of industrial wastewaters containing the bio-degradedlydifficult organic pollutants , NH3-N compounds andsuspended substances in high concentrations are increasingquickly. All circles of Chinese society and all levels ofgovernmental environmental protection departments are payingmore and more comprehensive attention to the series ofproblems caused by the high concentrated industrialwastewaters, such as water body pollut…
