Reagent-free photoelectro-Fenton system for real textile wastewater: Integrated hydrogen recovery, detoxification, and sludge-based catalyst reuse
This study presents a sustainable Photoelectro-Fenton (PEF) system using a sacrificial iron anode and graphite cathode for treating real textile wastewater under acidic conditions (pH 3), without external iron salts. RSM optimized the process (temperature, current, time, UV intensity), achieving 90 % TOC and 73 % color removal with a specific energy consumption of 43.2 kW h/kg TOC. Hydrogen generation reached 41 mL, and Daphnia magna immobilization dropped to 15 %. Notably, acidified iron-rich sludge was reused as a catalyst, providing up to 75 % TOC and 62 % color removal under photo-Fenton conditions. As a coagulant, it contributed an additional 50–70 % removal. This integrated reagent-free system offers an environmentally sound approach combining pollutant degradation, hydrogen recovery, toxicity reduction, and sludge valorization.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
