Special Issue Information

Dear Colleagues,

Currently, with the rapid increase of chemical production and use, the coexistence of multiple pollutants in wastewater has become a common phenomenon, which brings great challenges to conventional wastewater treatment processes. Meanwhile, the interaction between pollutants with different physicochemical properties produces obvious joint ecotoxicity to aquatic organisms and humans. Thus, it is extremely urgent to completely eliminate or minimize the contents of multiple pollutants in effluents before discharging them into receiving water bodies. The development of green and efficient treatment technology for complex wastewater is of great practical significance for reducing treatment costs, maintaining ecological environment sustainability, and protecting human health.

This Special Issue aims to collect information that will deepen our understanding of the need to apply the principles and concepts of sustainable development in the aspect of complex wastewater treatment. We are pleased to invite you to submit research or review articles on the principle and technology of sustainable development in complex wastewater treatment.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Sustainable water purification technology based on functional nano/micromaterials.
  • Sustainable technology for the selective removal of emerging contaminants in complex wastewater.
  • Multiple-pollutant elimination based on integrated technology (adsorption-photocatalysis, AOPs-membrane filtration, etc.).
  • Innovative biological process for complex wastewater remediation.

I look forward to receiving your contributions.

Currently, there is an urgent need to remediate heavy metals (HMs) and high alkalinity in the washing solution of fly ash (FA). This study investigated the remediation with simulated exhaust gases of two CO2 partial pressure and revealed the removal efficiency of target pollutants, mainly including Pb ions. The results verify that under the preferred conditions of 25 °C and 15 mL/min flow rate, bubbling two kinds of simulated flue gases could efficiently remove 97.9–99.2% of Pb ions. Moreover, the initial 40 min removal of Pb ions fits in a way with a pseudo-first-order equation. Based on the thermodynamic parameters, we infer that the removal of Pb ions was a spontaneous, exothermic, and entropy-decreasing process. Furthermore, residual HMs and terminal pH after remediation of the FA washing solution basically met the regulatory threshold values of the integrated wastewater discharge standard in China (GB 8978−1996). Additionally, the particles obtained from the washing solution of FA were identified as CaCO3, which was mainly composed of vaterite and calcite crystalline. This study provides a fundamental guide for remediating multiple pollutants in the washing solution of FA and simultaneously sequestrating carbon emissions from power plants and industries.

In the framework of sustainability, water shortages and water pollution are two important aspects to be considered. Proposing efficient and low-impact technologies is of paramount importance to promote circular economies associated with the use of water in the industrial context, especially in the textile industry. In this work, the application of a set of magnetic nanostructured adsorbents (MNAs) to cleanse metal ions from textile wastewaters was studied and analyzed. MNAs were generated with a low-cost process, involving iron (II/III) salts (e.g., chlorides), sodium or ammonium hydroxide solutions, and graphene oxide, obtained from graphite by a modified Hummers’ method at room temperature. The shape and the size were studied with transmission electron microscopy. Adsorbents were tested with different metal ions (e.g., copper, chromium (III), and nickel). Metal ion concentrations were analyzed by means of inductively coupled plasma optical emission spectroscopy (ICP-OES), and adsorption isotherms were characterized. From the results, the MNAs exhibited the capability of removing metal ions up to a yield of 99% for Cr3+, 94.7% for Cu2+, and 91.4% for Ni2+, along with adsorption loads up to 4.56 mg/g of MNAs.
