“…Existing wastewater treatment technologies can remove ordinary containments like TVS, nitrite and phosphorus, but meets certain challenges when dealing with contaminants of emerging concern that have only been recognized as harmful in recent years like chromium and various antibiotics. This is a promiment and important subject in the field of environmental engineering, and should be a focus point in any research related to wastewater treatment, with particular emphasis on nZVI research [7][8][9][10][11][12][13][14][15][16][17][18].…”

Microbial fuel cells (MFCs) are a promising and rapidly evolving discipline, which is mainly applied to convert chemical energy of urban wastewater into electrical energy. Based on past research achievements, iron components (zerovalent iron nanoparticles, Fe 2+ and Fe 3+ ) has positive enhancements on MFCs by increasing the activity of electroactive bacteria on anode chamber. In this study, the effect of zerovalent iron nanoparticles Fe 2+ , Fe 3+ and their combinations on a lab-scale double chamber MFCs was evaluated. Based on the results achieved, the best performance was 10 mg/L Fe 2+ modified anolyte, which achieved accumulative voltage improvement of 216.8%. Furthermore, it was found that more than 20 mg/L of total iron components reduces the power generation of MFCs and this is deemed excessively high for this application. Lastly, a removal rate of 91.5% for Total Volatile Solids (TVS) was achieved after 30 days of operation.

“…Organic nitrogen-containing pollutants are stable in structure, difficult to decompose and transform, and have a long residual time, which poses a greater risk of refractory degradation to organisms [24,68,69]. Among inorganic nitrogen-containing pollutants, nitrite nitrogen and nitrate nitrogen are the most harmful, which can cause serious damage to human and animal health such as methemoglobinemia, so the discharge of such substances needs to be strictly controlled [25,70,71].…”

Nanoscale zero-valent iron (nZVI) is highly efficient in environmental pollution control technology, owing to its unique zero-valent iron core-iron oxide surface, which exhibits exceptional adsorption and reduction properties. This paper provides a comprehensive understanding of the physical and chemical properties of nano-iron, with a primary focus on the preparation of nZVI. While nZVI finds extensive application in sewage treatment, it also demonstrates outstanding performance in the remediation of soil organic matter and heavy metal pollution, delivering excellent results and displaying good fluidity.

“…But we can only detect small amounts of hydrogen in the biogas because hydrogen is an intermediate metabolite during the AD process [8]. And there are also some modeling was used in some pollution removal research, it is better for us to understand how the system works, so it may be another good way to be used in investigating the AD system [9,10]. In recent years, much research has focused on hydrogen production by anaerobic digestion on how to increase hydrogen production.…”

Low hydrogen production which is only 10% of the gas production is a disadvantage of bio-hydrogen production in an anaerobic digestion system. The two-stage AD process can achieve hydrogen production and methane production in two reactors respectively. In most studies, the pH of the hydrogen-producing reactor is controlled at 5.5, at this time the main hydrogen-producing bacteria Clostridium butyricum can have the maximum hydrogen production rate. In addition, HRT, temperature, and the concentration of external additives are also important operating conditions for the two-stage AD process. When the added concentration of NZVI is over 30 mM, the methane production process will be inhibited, but the hydrogen production can be promoted. Therefore, how NZVI promotes hydrogen production in the twostage AD process is still worthy of attention in the future research.
