摘要
Abstract
Photocatalytic removal of CODCr from the biochemical effluent of Lurgi coal gasification wastewater by UV/TiO2 was studied.The main factors affecting the removal rate of CODCr were analyzed,including pH value,TiO2 dosage,reaction time and addition of H2O2.Experimental results showed that the neutral or acidic conditions were favored for the photocatalytic removal of CODCr from the biochemical effluent of Lurgi wastewater by UV/TiO2.Under the conditions that pH value was 7 and TiO2 dosage was 1.0 g/L,the removal rate of CODCr was 61.17％ after 4 hours.The effect of the addition of H2O2 on the removal rate of CODCr depends on the composition of the reaction.关键词
