摘要

在本研究中，利用实验室规模的环形反应器和太阳能管式反应器，采用均匀光fenton法降解硫代甲基杀菌剂。在实验室规模的反应器中，采用紫外光作为人工照射源。考察了过氧化氢(H2O2)投加量和初始污染物浓度对工艺效率的影响。通过测定总有机碳(TOC)来监测硫磷-甲基杀菌剂的降解效率。结果表明，不同H2O2用量对工艺效率有显著影响，而杀菌剂浓度对工艺效率影响不大。两个反应器显示出相似的效率，在120分钟的反应时间内达到80%的杀菌剂矿化。因此，两种反应器都能有效地从水溶液中降解硫代甲基。

Degradation of thiophanate-methyl fungicide by photo-Fenton process using lab-scale annular and solar tubular reactors

In this work, thiophanate-methyl fungicide was degraded by the homogeneous photo-Fenton process using lab-scale annular and solar tubular reactors. A UV light was used as artificial irradiation source in the lab-scale reactor. The influence of hydrogen peroxide (H2O2) dosage and initial pollutant concentration on the process efficiency was investigated. Degradation efficiency of thiophanate-methyl fungicide was monitored by measuring the total organic carbon (TOC). The results revealed that the variable H2O2 dosage showed remarkable effect on the process efficiency, whereas the fungicide concentration showed little influence. Both reactors showed similar efficiencies, reaching a fungicide mineralisation of 80% at 120 min of reaction time. Therefore, both reactors demonstrate to be effective on the thiophanate-methyl degradation from aqueous solution.
