Constructed wetlands are of increasing interest worldwide given that they represent an eco-technological solution to many environmental problems such as wastewater treatment. Turkey possesses approximately 70% of the world's total boron (B) reserves, and B contamination occurs in both natural and cultivated sites throughout Turkey, particularly in the north-west of the country. This study analyzes B removal and plant uptake of B in pilot plots of subsurface horizontal-flow constructed wetlands. Constructed wetlands were vegetated with Typha latifolia (referred to as CW1) and Phragmites australis (referred to as CW2) to treat wastewater from a borax reserve in Turkey--the largest of its type in the world and were assessed under field conditions. The B concentrations of water inflows to the systems were determined to be 10.2, 28.2, 84.6, 232.3, 716.4, and 2019.1 mg l(-1). The T. latifolia in the CW1 treatment group absorbed a total of 1300 mg kg(-1) B, whereas P. australis absorbed 839 mg kg(-1). As a result, CW1 had an average removal efficiency of 40.7%, while that of CW2 was 27.2%. Our results suggest that constructed wetlands are an effective, economic and eco-friendly solution to treating B mine wastewater and controlling the adverse environmental effects of B mining.
人工湿地越来越受到关注，因为它们是解决许多环境问题的生态技术解决方案，例如废水处理。土耳其拥有全球约 70%的总硼（B）储量，B 污染不仅发生在土耳其的自然和耕种场所，而且还发生在该国的西北部。本研究分析了 B 去除和植物吸收人工湿地地下水平流试点中的 B。人工湿地种植了芦苇（称为 CW1）和芦苇（称为 CW2），以处理来自土耳其硼砂矿的废水，这是世界上最大的硼砂矿，并在野外条件下进行了评估。系统进水的 B 浓度分别为 10.2、28.2、84.6、232.3、716.4 和 2019.1 mg l(-1)。CW1 处理组中的芦苇总共吸收了 1300 mg kg(-1) B，而芦苇吸收了 839 mg kg(-1)。因此，CW1 的平均去除效率为 40.7%，而 CW2 的去除效率为 27.2%。我们的研究结果表明，人工湿地是处理硼矿废水和控制硼矿开采对环境不利影响的有效、经济和环保的解决方案。
