摘要
本文分析了以颗粒活性炭和CuO为催化剂条件下,微波辐射对稻草浆蒸煮黑液的处理的效果,考察了CuO与活性炭总量、比例,微波辐射功率,微波辐射时间等对黑液处理效果的影响.得出以活性炭CuO为吸附催化剂在微波辐射条件下对稻草浆蒸煮黑液的处理效果非常理想.同时对微波辐射处理的反应机理进行了初步探讨.结果表明黑液中的木质素等有机污染物被氧化分解的过程是活性炭CuO吸附降解和微波诱导催化氧化协同作用的结果.该方法具有设备简单,操作方便,处理时间短,反应彻底,无二次污染物产生等优点,可用于处理含有难降解有机污染物的造纸废水.
This paper analyses the results of treating rice straw pulp black liquid using the technology of microwave radiation. The granular activated carbon and CuO are used as a catalyst. By using this method, the effect of effective factors such as the total amount, ratio, microwave power, acting time on treating black liquid is studied. Special mention is given here to the effect of treating this liquid is satisfied. The reaction mechanism of microwave radiation was researched into. These findings indicate that the oxidative decomposition process of lignin or organic pollutants is the result of activated carbon and CuO absorption-degradation cooperating with microwave induced oxidization. This approach is easy to operate, quickly to treat, completely to react and no new pollutants to form. So it is used to treat papermaking waste liquid of containing organic pollutes which is hardly degraded.
