Abstract

This study assessed the operational efficiency of a hybrid constructed wetland (CW) in its first year of use. The test facility was put into operation in September 2022 and has since been utilized to treat 0.4 m 3 /d of wastewater discharged from a forester’s lodge located in the Polesie National Park in Poland. The treatment plant consists of a two-chamber primary settling tank integrated with a pumping station, and a system of two beds – a vertical flow (VF) reed bed and a horizontal flow (HF) willow bed. During the research period (October 2022 to December 2023), 14 test runs were performed during which 56 sewage samples were collected for physico-chemical and microbiological assays. The results of these tests were used to determine the pollutant removal efficiency of the CW. The composition of treated wastewater was compared against the current Polish requirements for this type of facilities. The study also included measurements of influent and effluent volumes and the amount of rainwater entering the treatment plant. It was shown that precipitation in each month of the study accounted for between 6–34% of influent volume. The volume of wastewater discharged from the treatment plant during the study period was 11% lower than the volume of incoming wastewater combined with rainwater. It was found that the CW removed an average of over 90% of total suspended solids, BOD 5 , COD, Escherichia coli bacteria and fecal enterococci from wastewater. Slightly lower removal efficiencies were achieved in the case of total nitrogen and total phosphorus (60–74%). Already during the start-up period, the composition of treated wastewater discharged from the CW met the requirements set out in the current Polish legal regulations. The present study shows that hybrid VF-HF constructed wetlands can be recommended for use in protected areas for wastewater treatment and protec - tion of water against eutrophication.

位于波兰波列西国家公园的混合型人工湿地在启动期间的运行效率

本研究评估了混合型人工湿地（CW）第一年的运行效率。该试验设施于 2022 年 9 月投入运行，用于处理波兰 Polesie 国家公园内一家林务员小屋每天排放的 0.4 立方米废水。该处理厂由一个两室初沉池和一个泵站以及一个由垂直流（VF）芦苇床和水平流（HF）柳树床组成的双床系统组成。在研究期间（2022 年 10 月至 2023 年 12 月），共进行了 14 次试验，收集了 56 份污水样本进行物理化学和微生物检测。测试结果用于确定化学武器的污染物去除效率。经过处理的废水成分与波兰目前对此类设施的要求进行了比较。研究还包括进水量和出水量以及进入处理厂的雨水量的测量。结果显示，研究期间每个月的降水量占进水量的 6% 至 34%。在研究期间，处理厂排出的废水量比流入的废水量加上雨水量低 11%。研究发现，化学武器平均去除废水中 90% 以上的总悬浮固体、生化需氧量 5、化学需氧量、大肠杆菌和粪肠球菌。总氮和总磷的去除率略低（60%-74%）。在启动期间，化武处理厂排放的废水成分就已达到波兰现行法律规定的要求。本研究表明，VF-HF 混合型建造湿地可推荐用于保护区的废水处理和水体富营养化保护。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
