摘要 活性炭对含酚污水中影响COD值的微量有机污染物具有吸附作用,将其活化处理后,用Cu(NO3)2溶液浸渍,并在烘箱中将铜还原热固在其微表面上,采用固定床式装置,利用活性炭的吸附和铜的催化作用,降低有机污染物分解的活化能并实现酚类的深度降解及达标排放.结合F en ton反应机理,实验探讨了Cu2+非均相催化氧化机理.该方法集吸附、催化氧化和过滤于一体,为湿法催化处理污水的工程化提供了可能. Aetiearbon can absorb and gather --OH,--X etc, in the phenolic effluent which organic micro-pollutant may affect COD value. After activation treatment, impregnates acticarbon with Cu (NO3)2 solution, then puts it into a drying oven, copper will be reduced and thermosetting on its micro-surface. Taking the static bed as the equipment, the absorption of acticarbon and catalysis of copper are used to reduce organic matter's decomposition activity energy, thus phenols will be drastically degraded and the effluent can be drained under the standard. Refering to Fenton reaction mechanism, experiment has been done to study the heterogeneous catalyzed oxidation mechanism of Cu^2+. This method incorporates absorption, catalyzed oxidation and fihration as one and makes it possible to catalytically treat wastwater by wet method.
