چکیده
Constructed wetlands, in addition to low cost, simple guidance, low technology and low energy consumption, is a suitable method for removing pollutants from water that is effective and improving the environment. Based on the literature, many existing technologies can, and have been, integrated and coupled with CWs to overcome their individual disadvantages and improve their performance and ability. This study investigated in principle the performance of a new CW-MFC mainly in wastewater treatment and bioelectricity generation. The results showed MFC improved the ability of CW to meet the primary thresholds of efficient wastewater treatment. The maximum removal rate of the load in continuous and batch systems was 890 (74.1%) and 909.8 (75.8%) mg/L, respectively. The maximum voltage output of the system voltage in continuous and batch mode are 1013 and 639 mW, respectively. The maximum of the electrical power density of the system in both continuous and batch modes was 9.21 and 3.4 mW/m. Respectively. The ability to absorb heavy metals as a key point of the wetland system has been measured first, by measuring the iron content of the system. The removal efficiency of iron by the combined system mode in this study is 98% which meets the threshold for drinking water. Second, by the plant was measured by an atomic spectrometer; finally, 98.88 mg/L (82.8%) of the total iron found in the wastewater was removed by the plant and in the root, stem, and leaf It was saved. The effluent removal efficiency, TSS, and sodium in the wastewater were 39, 66.75 and 53 percent, respectivelyکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
