摘　　要：分别以中压汞灯和太阳光作光源、TiO2为催化剂,进行光催化降解杨木APMP废水的实验,考察了TiO2用量、H2O2用量、pH值、光照时间4个因素对降解效果的影响。结果表明,TiO2用量为4 g/L、H2O2用量16 g/L,CaO调节废水初始pH值为9的条件下,光照6 h后,CODCr的去除率和脱色率分别达到了70.2%和94.1%。即采用TiO2/H2O2光催化处理APMP废水是有效和可行的。The photocatalytic oxidation of Poplar APMP wastewater with TiO2 as catalyst was studied. The TiO2 and H202 dosage, pH and roasted time were determined and the result showed that the removal rate of CODCr and chromaticity was 70.2% and 94.1% respectively when the amount of TiO2 was 4 g/L, the amount of H2O2 was 16 g/L, initial pH value was 9 by CaO, and mercury pump radiation was for 6 h.
