Fluopyram is a novel broad-spectrum fungicide with nematocidal activity, and as an extensively used pesticide, it could cause toxicity in nontarget organisms. The aim of this study was to explore the efficiency of five horizontal subsurface flow (HSF) constructed wetlands (CWs) to remove fluopyram from rinsing water produced during the cleaning of pesticide spraying equipment. Four CWs, namely WG-R, WG-R-P, WG-C, and WG-U, contained fine gravel as porous media. WG-R and WG-R-P were planted with Phragmites australis, WG-C with Typha latifolia, and WG-U was left unplanted. Bioaugmentation with plant growth-promoting rhizobacteria was conducted in WG-R-P unit. The fifth unit (WGZ-R) planted with Phragmites australis and contained gravel and zeolite as porous media. All of CWs were loaded on a daily basis from December 2019 to January 2021 with water fortified with fluopyram. The removal rate follows the pattern of WG-R-P (70.67%) > WGZ-R (62.06%) > WG-C (59.98%) > WG-R (36.10%) > WG-U (25.09%). The most important parameters affecting the fluopyram removal were bioaugmentation, zeolite presence in porous media, and plant species. The WG-R-P unit showed higher fluopyram removal in comparison to the WG-R (increase about 96%), the zeolite increased the fluopyram removal by 72%, and the WG-C unit showed 66% higher fluopyram removal than the WG-R unit.

氟吡菌酰胺是一种新型广谱杀菌剂，具有杀线虫活性，作为一种广泛使用的杀虫剂，可对非靶标生物产生毒性。本研究的目的是探讨五种水平潜流 (HSF) 人工湿地 (CW) 从农药喷洒设备清洗过程中产生的冲洗水中去除氟吡菌酰胺的效率。四个 CW，即 WG-R、WG-RP、WG-C 和 WG-U，含有细砾石作为多孔介质。WG-R和WG-RP种植了芦苇，WG-C种植了香蒲，WG-U不种植。使用促进植物生长的根际细菌进行生物强化是在 WG-RP 单元中进行的。第五单元（WGZ-R）种植了芦苇并含有砾石和沸石作为多孔介质。从 2019 年 12 月至 2021 年 1 月，所有 CW 每天都装载氟吡菌酰胺强化水。去除率遵循 WG-RP (70.67%) > WGZ-R (62.06%) > WG-C (59.98%) > WG-R (36.10%) > WG-U (25.09%) 的规律。影响氟吡菌酰胺去除的最重要参数是生物强化、多孔介质中沸石的存在和植物种类。与 WG-R 相比，WG-RP 装置的氟吡菌酰胺去除率更高（增加约 96%），沸石使氟吡菌酰胺的去除率提高了 72%，WG-C 装置的氟吡菌酰胺去除率比 WG-R 高 66%单元。
