Simultaneous removal of heavy metals and bioelectricity generation in microbial fuel cell coupled with constructed wetland: an optimization study on substrate and plant types

Lu Wang et al.

Summary: The study successfully removed heavy metals (Zn and Ni) from sludge using a microbial fuel cell coupled with constructed wetland (CW-MFC), while also generating electricity. It was found that the CW-MFC system with a construction of GAC and water hyacinth showed the best performance in heavy metal treatment.

Lead (Pb) removal from contaminated water using constructed wetland planted with Scirpus grossus: Optimization using response surface methodology (RSM) and assessment of rhizobacterial addition

Bieby Voijant Tangahu et al.

Summary: This study optimized the removal of lead from water using a constructed wetland with Scirpus grossus. The results showed that the optimal conditions for lead removal were an initial concentration of 37 mg/L, a retention time of 32 days, and no aeration. Bioaugmentation with rhizobacteria slightly improved lead removal and adsorption by plants, but did not have a significant impact.

Regulation of heavy metals accumulated by Acorns calamus L. in constructed wetland through different nitrogen forms

Jun-Feng Wang et al.

Summary: This study investigated the accumulation of heavy metals by wetland plants under different nitrogen forms influences in constructed wetlands. The findings showed that influents with ammonia could enhance the mobilization of heavy metals from their precipitation fractions and their uptake by plants in the wetland, leading to higher removal efficiency and promoting plant growth and metabolic functions. Overall, regulating water treatment processes to increase ammonia could provide a feasible method for enhancing the accumulation of heavy metals by wetland plants.
