摘　　要：采用微波辐射技术对造纸工业废水进行处理研究.以FeSO4负载炉渣为吸波催化载体,微波辐射处理造纸废水,可有效降解其有机污染物.炉渣微波活化活性优于普通炉活化.正交优化实验得到微波处理最优条件为:负载型炉渣用量为28 g、微波辐射时间为17 min、微波功率为800 W,最优条件下COD去除率可达95%.活化炉渣重复使用,COD去除率明显下降,炉渣破损是效率下降的主要原因.Microwave radiation technology was used to treat paper waste water. Using FeSO4-loaded slag as the wave-absorbing and oxidation-catalyzlng carrier, microwave radiation could effectively decompose organic pollutant in paper waste water. The activity of slag treated by microwave was better than that by normal furnace. The optimal conditions were determined by orthogonal experiment： the consumption of supported slag was 28 g per 50 mL waste water, time of microwave treatment was 17 min, and power of microwave radiation was 800 W. Under the optimal conditions, the removal rate of COD could reach 95%. The activated slag was reused, and some must be damaged; therefore the removal rate of COD declined.
