The use of recycled glass as a substrate for constructed wetlands was assessed through two studies. The first study examined the dissipation of atenolol, carbamazepine, and sulfamethoxazole in mesocosm-modeled wetlands using glass or limestone gravel as substrates, with or without cattails (Typha spp.). Following pseudo-first-order kinetics, atenolol dissipated the fastest from the water surface of the mesocosms (t_1/2~1 day), followed by sulfamethoxazole (t_1/2~14 days), and carbamazepine (t_1/2~48 days), with no significant differences across treatments. Increased half-lives were observed at greater depth, likely due to light screening. A Monte Carlo sensitivity analysis diagnosed sunlight absorption rates and second-order hydroxyl-mediated indirect photolysis rates to be the main sources of uncertainty in our dissipation rate estimates, compared to our observed rates. The second study examined in situ pharmaceutical removal in tertiary pilot-scale subsurface filters made of crushed recycled glass or sand in a wastewater treatment facility in Manitoba, Canada. Glass and sand showed no significant differences for pharmaceutical removals; atenolol and metoprolol were removed below limits of detection, while carbamazepine and sulfamethoxazole persisted over a retention time of 24 h. Overall, recycled glass performed similarly to traditional substrates for wetland-based wastewater treatment.

通过两项研究评估了使用回收玻璃作为人工湿地基材的情况。使用玻璃或石灰石碎石作为底物，有或没有香蒲第一研究审查阿替洛尔，卡马西平，和磺胺甲基异恶唑的围隔中建模的湿地耗散（香蒲属。）。根据拟一级动力学，阿替洛尔从中层水面消散最快（t _1/2 ~1 天），其次是磺胺甲恶唑（t _1/2 ~14 天）和卡马西平（t _1/2~48 天），处理之间没有显着差异。在更深的地方观察到半衰期增加，可能是由于光屏蔽。与观察到的速率相比，蒙特卡罗敏感性分析诊断出阳光吸收率和二阶羟基介导的间接光解率是我们耗散率估计中不确定性的主要来源。原位检查的第二项研究在加拿大马尼托巴省的废水处理设施中，在由碎回收玻璃或沙子制成的三级中试规模地下过滤器中去除药物。玻璃和沙子在药物去除方面没有显着差异；阿替洛尔和美托洛尔的去除率低于检测限，而卡马西平和磺胺甲恶唑的保留时间为 24 小时。总体而言，再生玻璃的性能与湿地废水处理的传统基材相似。
