Industrial wastewaters represent a serious threat to the environment due to their variable and complex composition. Though mostly mechanical systems are used for treatment of such wastewater, there is growing need for sustainable and cost-effective solutions, especially in low-income regions. In this study, a horizontal sub-surface flow Constructed Wetland (HSFCW) system was used for the first time to treat wastewater from a glass manufacturing industry in Iran. In order to de-risk the treatment approach, a pilot system consisting of a settling tank and a HSFCW was first tested for 4 months. The results of the pilot study were then used to build the full-scale CW system treating 10 m³/day. In general, the tested design proved to be very effective reaching high removal rates of BOD, COD, and TSS (90, 90, and 99, respectively), as also for TN and TP (>90%). The high efficiency of the tested system allowed for the recycle and reuse of the treated effluent in the glass manufacturing processes, reducing this way the fresh water consumption in the glass industry and the related operational costs.
工业废水由于其多变且复杂的成分，对环境构成了严重威胁。尽管大多采用机械系统来处理此类废水，但对于可持续且具有成本效益的解决方案的需求日益增长，尤其是在低收入地区。在这项研究中，首次使用水平潜流人工湿地（HSFCW）系统来处理伊朗一家玻璃制造工厂的废水。为了降低处理方法的风险，首先对一个由沉淀池和 HSFCW 组成的试验系统进行了为期 4 个月的测试。然后，根据试验研究的结果，建造了一个处理量为 10m³/天的全规模 CW 系统。总的来说，经过测试的设计被证明非常有效，达到了高的 BOD、COD 和 TSS 去除率（分别为 90%、90%和 99%），以及 TN 和 TP 的去除率（>90%）。该试验系统的高效率使得处理后的废水能够在玻璃制造过程中循环再利用，从而减少了玻璃工业的新鲜水消耗和相关的运营成本。
