Inspired by plant transpiration, an attached microalgae−simulated plant system was designed to enhance the transpiration of reverse osmosis concentrated water (i.e., W_ROC) and realize the conversion of pollutants to microalgae biomass. The results showed that the production rate of clean water could reach as high as 14.84 L·m⁻²·day⁻¹, which was significantly influenced by the humidity of the air and the growth status of the attached microalgae. Moreover, the enhancement of water evaporation by microalgae was more obvious under relatively low humidity. Pollutants, transported along with the water, could transform into microalgae biofilm or crystallize at the top of the microfiber. TN and TP transformation into biomass resources were maximized in 40% diluted W_ROC, with efficiencies of 60.91% and 38.49%, respectively. Of note, the accumulation of phosphorus in the micro-environment of attached microalgae may inhibit microalgal growth in the later stages of cultivation, owing to the relatively low movability. Hence, this system could be applied for high-efficiency wastewater purification, especially under high humidity. Wastewater dilution and periodic microalgae harvest could guarantee the attached microalgae growth and increase the pollutant-bioresource conversion rate.

通过附着的微藻模拟植物增强蒸腾作用，实现反渗透浓缩水 (WROC) 的零排放

受植物蒸腾作用的启发，设计了一种附着微藻模拟植物系统，以增强反渗透浓缩水（即W _ROC）的蒸腾作用，实现污染物向微藻生物质的转化。结果表明，净水产率可达14.84 L·m ^-2 ·day ^-1，受空气湿度和附着微藻生长状况影响显着。此外，在相对较低的湿度下，微藻对水分蒸发的促进作用更为明显。污染物与水一起运输，可以转化为微藻生物膜或在微纤维顶部结晶。TN 和 TP 转化为生物质资源在 40% 稀释 W 中最大化_{ROC 的}效率分别为 60.91% 和 38.49%。值得注意的是，附着的微藻微环境中磷的积累可能会抑制微藻在培养后期的生长，因为其移动性相对较低。因此，该系统可用于高效废水净化，特别是在高湿度下。废水稀释和定期微藻收获可以保证附着的微藻生长，提高污染物-生物资源转化率。
