This investigation is the first of its kind to evaluate the interrelation of sulphate (SO₄^2-) with conductive materials as well as their individual and synergetic effects on the removal of ammonium and organic pollutants in electroactive wetlands, also known as constructed wetland (CW) - microbial fuel cell (MFC). The role of MFC components in CW was investigated to treat the sulphate containing wastewater under a long-term operation without any toxicity build-up in the system. A comparative study was also performed between CW-MFC and CW, where sulphate containing wastewater (S-replete) and without sulphate wastewater (S-deplete) was assessed. The S-replete showed high NH₄⁺ removal than the S-deplete, and the requesnce of removal was: CW-MFC-replete > CW-MFC-deplete > CW-replete > CW-deplete. The chemical oxygen demand (COD) removal was high in the case of CW-MFC-replete, and the sequence of removal was CW-MFC-replete > CW-MFC-deplete > CW-deplete > CW-replete. X-ray photon spectroscopic study indicates 0.84% sulphur accumulation in CW-MFC-replete and 2.49% in CW-replete, indicating high sulphur precipitation in CW without the MFC component. The high relative abundance of class Deltaproteobacteria (7.3%) in CW-MFC-replete along with increased microbial diversity (Shannon index = 3.5) rationalise the symbiosis of sulphate reducing/oxidising microbes and its impact on the treatment performance and electrochemical activity.

本研究首次评估硫酸盐 (SO ₄ ^2- ) 与导电材料的相互关系，以及它们对电活性湿地（也称为人工湿地 (CW)）中铵盐和有机污染物去除的单独和协同作用。 ) - 微生物燃料电池 (MFC)。研究了 MFC 组件在 CW 中的作用，以在长期运行下处理含硫酸盐废水，而不会在系统中产生任何毒性。还在 CW-MFC 和 CW 之间进行了比较研究，其中评估了含硫酸盐废水 ( S-replete ) 和不含硫酸盐废水 ( S-deplete )。的S-充满表现出较高的NH ₄ ⁺去除率高于S- deplete，去除要求为：CW-MFC-       replete > CW-MFC-deplete > CW-replete > CW-deplete。CW-MFC-replete的化学需氧量（COD）去除率高，去除顺序为CW-MFC-replete  >  CW-MFC-deplete  >  CW-deplete  >  CW-replete。X 射线光子光谱研究表明，在CW-MFC-replete 中硫积累为 0.84%，在CW-replete 中为2.49% ，表明在没有 MFC 组分的 CW 中硫沉淀量高。班级相对丰度高δ-变形菌（7.3％）在CW-MFC-充满具有增加的微生物多样性（Shannon指数沿 =  3.5）硫酸盐合理化的共生还原/氧化的微生物和其上的处理性能和电化学活性的影响。
