摘要
首先采用复合混凝剂对造纸废水二级出水进行了预处理,再用臭氧进行氧化处理。研究了在不同臭氧量、pH条件下,臭氧氧化法对造纸废水中COD和色度的去除效果,及不同臭氧产生速率和反应时间对COD与色度的去除效果,分析了臭氧氧化污染物的机理。结果表明,臭氧氧化效果随臭氧量、反应时间的增加而增强,但增强幅度越来越小;臭氧投加速率为13.98mg/min、停留时间为30min时,COD和色度去除率分别可达62.3%和99.5%,去除效果明显。
The second grade effluent water of paper and pulp industrial wastewater has firstly been pretreated composite coagulant, and then, the oxidation treatment with ozone has been carried through. The effect of ozonation on the COD and chroma removal rates of the pulp wastewater under different conditions （such as the dosage of ozone, pH）, and the effect of different ozone producing speed, and reaction time on its COD and chroma removal rates are studied. The mechanism of ozonation is analyzed. The result indicates that the ozonation effect increases with the increase of ozone dosage and reaction time, but the increasing extent gets less and less. The removal rates of COD and chroma are 62.3% and 99.5% respectively, when ozone adding speed is 13.98 mg/min and retention time 30 min. The removal effects are significant.
