水固液微界面氧化还原反应过程与污染物控制研究

Process of redox reaction and contaminants control on microinterface at water/solid

本文介绍了3个反应体系,包括铁锰复合氧化物氧化吸附除砷体系、铁氧化物包覆零价铁光芬顿催化和负载型多价态锰氧化物臭氧催化体系,通过固液微界面不同的氧化还原反应,实现了对水中砷和难降解有机污染物的高效去除.重点介绍了不同氧化还原反应对污染物转移转化的作用机制,说明了水体中固液微界面氧化还原反应,对污染物的转移转化起着重要作用.

Arsenic and refractory organic compounds were highly effectively removed respectively through the different redox reactions on micro-interface at water/solid in three systems,which included Fe-Mn binary oxide adsorbent for removal of arsenic; photo-Fenton of Iron oxide coated on Fe^0 and catalytic ozonation of supported MnOx for removal of refractory organic compounds. The function mechanism of different redox reactions were investigated for transfer and transformation of contaminants. All informations from different experiments verified that the redox reactions on microinterface at water/solid play an important role in the transfer and transformation of contaminants in water.
