Under the dual pressures of environmental pollution and energy shortage,microbial fuel cells（ MFCs） have been paid more attention to due to their unique advantages of high efficiency,high cleanliness,and environmental protection,and have become a research hotspot in the current environmental field. In this study,advances in the application of MFCs in wastewater treatment were summarized,and main problems were analyzed.展开更多

The aim of this study is to compare the performance of the photo,Fenton, photo-Fenton and ozone–photo–Fenton processes in terms of color removal and chemical oxygen demand(COD) removal of distillery industrial effluent together with the associated electrical energy per order. It was observed from the experimental results that the O_3/UV/Fe^(2 +)/H_2O_2 process yielded a 100% color and95.50% COD removals with electrical energy per order of 0.015 k W·h·m^(-3) compared to all other combinations of the AOPs. The effects of various operating parameters such as H_2O_2 and Fe^(2+) concentration, effluent pH, COD concentration and UV power on the removal of color, COD and electrical energy per order for the ozone–photo–Fenton process was critically studied and reported. The color and COD removals were analyzed using a UV/Vis spectrometer and closed reflux method.展开更多
