摘　　要：采用CuO-MnO2-La2O3为催化剂,以催化湿式氧化技术处理噻螨酮生产过程中产生的的高浓度有机废水。试验结果表明,用该复合催化剂在处理此种有机废水时表现出较好的催化活性。在230℃,氧气分压为2.5MPa和pH值为7.3的条件下,当废水CODCr的质量浓度为15 730 mg/L,在120 min内,CODCr去除率达到96.1%,而在相同条件下未加催化剂的湿式氧化CODCr去除率只有50.3%。A catalytic wet air oxidation technology was used to treat high concentration organic wastewater from the production of hexythiazox with CuO-MnO2- La2O3 as catalyst. The results showed that, the said complex catalyst displayed relatively high catalytic activity when treating this kind of organic wastewater. Under the condition that the temperature was 230℃, the oxygen partial pressure was 2.5 MPa and the pH value was 7.3, when the mass concentration of CODCr was 15 730 rag/L, 96.1% of the CODCr could be removed from the wastewater in 120 min, while the removal rate of CODCr by WAO without adding the catalyst was only 50.3% under the same condition.
