O_3/H_2O_2催化氧化对苯二酚的影响因素及急性毒性变化
|
摘要
研究了O_3/H_2O_2催化氧化对苯二酚的去除效果及氧化过程中产物的急性毒性变化情况,并探讨了O_3/H_2O_2催化氧化对苯二酚的反应机理。结果表明:O_3/H_2O_2在中性条件下氧化对苯二酚反应中,通过H_2O_2和O_3分子联合作用(O_3投加量为210 mg/L、H_2O_2投加量为0.15%)可完全去除对苯二酚(浓度为150 mg/L)以及42%的TOC。以污染物在水环境中对发光细菌的抑光率为毒性指标,反应过程中的毒性作用先增大后减小。O_3/H_2O_2氧化是一种高效去除酚类化合物、降低急性毒性的方法,具有良好的应用前景。
This paper studied the removal effect of hydroquinone by O_3/H_2O_2 catalytic oxidation and the acute toxicity 's change of products during this oxidation process,and the reaction mechanism of this catalytic oxidation was discussed. The experimental results showed that hydroquinone was oxidized by the combined effect of H_2O_2 molecules and O_3 molecules( the hydroquinone was 150 mg/L),TOC of 42% could be completely removed with O_3 dosage of 210 mg/L concentration and the0. 15% H_2O_2 dosage. Taking the light restraining rate of pollutants to luminescent bacteria in the water environment as the toxicity index,the toxic effects in the process firstly increased and then declined. O_3/H_2O_2 oxidation was an efficient method to remove phenolic compounds and reduce acute toxicity,and it had a good application prospect.
