In this work, we have studied the removal of eight pesticides, commonly used in fruit crops, in agro-wastewater generated in commercial farms by the cleaning of trace of phytosanitary products in containers and tanks from treatment equipment. The studied pesticides were acetamiprid, cyproconazole, cyprodinil, difenoconazole, fenhexamid, hexythiazox, myclobutanil and thiamethoxam. The trials were performed in a pilot facility located in Murcia (SE of Spain), using natural sunlight and titanium dioxide (TiO) in tandem with NaSO. Five photocatalytic treatments were carried out during autumn 2017. Results show that the mean (n = 5) final amount was about 13% of the initial pesticide mass present in agro-wastewater. Therefore, we have proved that this technology could be used for tackling the elimination of pesticide residues in agro-wastewater and has favourable prospects of being applied in the water treatment sector.
在这项工作中，我们研究了通过清洗农用设施中容器和罐体内痕量植物保护产品来去除商业农场中农业废水中的八种常用农药，这些农药包括乙虫脒、三唑酮、嘧菌酯、咯菌腈、苯醚甲环唑、噻虫嗪、灭蝇胺和噻虫啉。研究是在位于西班牙东南部穆尔西亚的一个试点设施中进行的，使用自然阳光和二氧化钛（TiO）与 NaSO 串联。2017 年秋季进行了五次光催化处理。结果表明，（n=5）初始农药质量的最终平均残留量约为 13%。因此，我们已经证明，这项技术可用于解决农业废水中的农药残留问题，并且在水处理行业具有良好的应用前景。
