Soil/Sediment Remediation and Wastewater Treatment

Topic Information

Dear Colleagues,

The continuous discharge of hazardous substances (e.g., organic contaminants, inorganic nutrients, and potentially toxic elements) into the soil/sediment system through wastewater and other routes has led to harmful effects on the environment and human health. Several strategies were proposed to deal with this issue, but novel options beyond traditional approaches are needed to unlock the full potential of these waste streams while ensuring environmental protection.

This Topic, entitled “Soil/Sediment Remediation and Wastewater Treatment”, promotes novel environmental science and technology works, mainly including soil/sediment remediation and wastewater treatment methods. With this Topic, original research and review articles, case and technical reports, and short communications are considered for publication. Investigation themes may be related, but are not limited to:

• Emerging pollutants (e.g., microplastics, antibiotics, herbicides);
• Bioremediation, phytoremediation, bioaugmentation and biostimulation;
• Advanced oxidation processes for soil/sediment treatment;
• Sustainable adsorbents (e.g., biochar) aimed at pollutant removal;
• Biosorption and biocoagulation;
• Thermal remediation;
• Physico-chemical techniques for resource recovery from wastewater;
• Nutrient recovery from wastewater;
• Phosphorus removal and recovery (e.g., chemical precipitation, PAO);
• Biological treatments for wastewater (e.g., biological nutrients removal);
• Innovative system for wastewater treatment (e.g., membrane-based systems);
• Renewable energy from sludge (e.g., biomethane, biohydrogen, syngas);
• Pretreatment methods for the improvement of biogas potential;
• Anaerobic fermentation modeling;
• Digestate treatment (e.g., removal of nitrogen, sanitization).

We look forward to receiving your contributions.

Abstract

Road-deposited sediments (RDS) from 28 sites in Beijing were studied and analyzed for eight heavy metals. In RDS, the levels of Cr, Ni, Cu, Zn, As, Cd, Pb and V were 2.76, 1.11, 2.40, 1.65, 1.09, 6.52, 4.13 and 0.06 times the background [...] Read more.

Road-deposited sediments (RDS) from 28 sites in Beijing were studied and analyzed for eight heavy metals. In RDS, the levels of Cr, Ni, Cu, Zn, As, Cd, Pb and V were 2.76, 1.11, 2.40, 1.65, 1.09, 6.52, 4.13 and 0.06 times the background values, respectively. The levels were rated in accordance with the geoaccumulation index (Igeo) as follows: Cd>Pb>Zn>Cu>Cr>Ni>As>V. In the four functional zones, the potential ecological risk index method showed that most of the heavy metals have environmental risk index values (${\mathrm{E}}_{\mathrm{r}}^{\mathrm{i}}$) of less than 40, but the multifactor environmental risk value (RI) for Pb in the transportation area exceeded 150. Four functional areas had Cd values greater than 160, exhibiting the highest risk. The human health risk assessment revealed that exposure pathways followed this decreasing order: ingestion > dermal > inhalation. Three DOM fractions were resolved in the sediments of the four functional zones, including terrestrial fulvic-acid-like fractions (C1), humic-acid-like fractions (C2), and tryptophan-like fractions (C3), and the DOM fractions were affected by both exogenous and endogenous sources. A positive correlation existed between DOM and Ni and Cu in the transportation zone, and the correlation between DOM and heavy metals in other zones was not apparent. In conclusion, heavy metals in different functional zones affected the concentration and characteristics of DOM, and there was a strong correlation between heavy metals and DOM concentration and features.
