Efficacy and power production performance of constructed wetlands coupled with microbial fuel cells for the advanced treatment of saline tailwater from wastewater treatment plants
In this study, the effects of different electrode materials and salt-tolerant plants on the efficacy and power production performance of constructed wetlands coupled microbial fuel cells (CW-MFCs) were analyzed for the advanced treatment of saline tailwater from wastewater treatment plants (WWTPs). The results showed that when carbon felt was used as the cathode material, the voltage was 165.45 ± 14.90 mV after system stabilization, the maximum power density was 3.20 mW/m when the current density was 25.58 mA/m, and the power production performance of carbon felt was better than that of common titanium mesh and granular activated carbon-stainless steel mesh cathode materials ( < 0.05). When the two groups of systems were operated and stabilized, the average removal rates of TN, TP, NH-N and COD in RS-CW-MFC were 86.48 %, 88.1 %, 82.67 % and 88.96 %, respectively, and those of TN, TP, NH-N and COD in RN-CW-MFC were 84.33 %, 87.34 %, 81.63 % and 87.64 %, respectively. Salinity enhanced the power production efficiency by increasing ionic strength and decreasing the internal resistance of the system. The microbial community in the saline tailwater systems gradually evolved toward salt-tolerant species, which enhanced the power production efficiency of the system without affecting the treatment of traditional pollutants in the CW-MFC systems.
期刊介绍:
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
