Special Issue Information

Dear Colleagues,

This Special Issue, "Research on Municipal Wastewater and Rural Domestic Sewage Treatment and Utilization of Solid Waste Resources", aims to collect original research articles and reviews on municipal wastewater and rural domestic sewage treatment, and on the application of new techniques that favor sustainable wastewater treatment. Moreover, we welcome contributions from different perspectives, such as sustainability and materials science, that propose solutions for the disposal of solid wastes to promote the utilization of solid waste resources. Moreover, we welcome contributions related to the separation and purification of water, air and solids.

Therefore, we hope that this Special Issue will enable researchers to share ideas on the treatment of wastewater and solid wastes and complement the existing literature. For this reason, we encourage submissions from researchers working in the purification of wastewater and the utilization of solid wastes.

We look forward to receiving your contributions.

Modified persimmon peel–montmorillonite composites (PMHC-KOH/NaHCO3) for efficient and rapid removal of methylene blue (MB) were synthesized using hydrothermal carbonization and simple alkali impregnation. The surface properties and material compositions of the hydrochars were determined with SEM, zeta potential, and XRD, and the adsorption mechanism of MB on two modified hydrochars was analyzed with FTIR, XPS, and DFT calculation. The results showed that modified hydrochars with a rough surface structure and rich oxygen-containing groups exhibited a strong affinity for MB, and the adsorption capacity of PMHC-NaHCO3 and PMHC-KOH for MB reached 121.28 mg/g and 278.41 mg/g, respectively, with PMHC-KOH achieving more rapid adsorption of MB, at a rate of 0.043 g/mg/min. After five adsorption/desorption cycles, the two modified hydrochars still maintained a high adsorption rate of MB (92.32%/98.43%). The excellent adsorption performance of the modified hydrochars was attributed to hydrogen bonding, π-π interaction, electrostatic attraction, and ion exchange. DFT calculations revealed that oxygen-containing groups of the modified hydrochars played an important role in the adsorption of MB and confirmed that electrostatic attraction, hydrogen bonding, and π-π interactions were the key forces for rapid and efficient adsorption of MB. The prepared adsorbents gave full play to the regenerative applicability of agricultural waste, the simple alkali impregnation method eliminated the need for the additional cost of pyrolysis and activation, and their application in MB adsorption realized the treatment of waste with waste.
