Special Issue Information

Dear Colleagues,

The activity of people will exert a negative impact on the environment, especially industrial production and daily life, which can generate large amounts of industrial wastewater (such as coking wastewater, polymer-flooding wastewater, printing and dyeing wastewater, landfill leachate, pharmaceutical wastewater, and mining wastewater) and municipal sewage, respectively. Due to the existence of various refractory organic pollutants, the direct discharge of the contaminated water into natural water may cause serious damage to water ecology and the water environment, affecting the sustainable development of water resources throughout the world. Thus, the effective removal of organic pollutants in contaminated water is the first barrier to maintaining a high-quality living environment for human beings.

The aim of this Special Issue is to promote the development of the treatment of organic wastewater. Specifically, it is interested in the studies about the preparation methods and working mechanism of heterogeneous Fenton-like catalyst and adsorbent, the microbial enhancement means concerning the degradation of various refractory organic pollutants, the microbial mechanisms involved in the relevant processes, the effects of the treated pollutants on the natural water environment, the remediation/recovery mechanism of nitrogen, pilot studies or practical applications by electrochemical/chemical technologies, and the electrocatalytic conversion of carbon dioxide.

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

  • Synthesis and application of Fenton-like catalyst/adsorbent in wastewater treatment;
  • Removal of organic pollutants by Fenton-like, adsorption, electrochemical process, and biochemical processes;
  • Application of physical field in the degradation of organic pollutants;
  • Microbial community investigation concerning the enhanced treatment of organic wastewater and analyses of the metabolic mechanisms involved;
  • Removal/recovery of nitrogen by electrochemical/chemical technologies;
  • Integrated experimental and computational insights into the electrochemical process;
  • Electrocatalytic reduction of carbon dioxide.

We look forward to receiving your contributions.

This study focuses on the riverbed sediments in the Changsha-Zhuzhou-Xiangtan (CS-ZZ-XT) section of the lower reaches of the Xiangjiang River. Principal element analysis, ecological risk analysis, and early warning methods were used to explore the distribution pattern and risk assessment of various chemical elements in the sediments. The results indicated that the vertical distributions of Sc, Co, Th, and U were more homogeneous, while Cr, V, Cu, and Ni distributed heterogeneously with significant changes. Risk assessment of heavy metals was explored by using the Geoaccumulation index, potential ecological risk index, and ecological risk index, suggesting that the contamination levels followed: ZZ > XT > CS. ZU and ZX points in the ZZ section exhibited the higher ecological risk. The ecological risk of heavy metals followed the order of: Pb > Cu > Zn > Ni > Co > Mn > V > Cr, and the contamination of Cd and Mn was located at the severe warning condition. Additionally, it was suggested that Th, U, Pb, Zn, Cu, and Mn mostly originated from both anthropogenic activities and natural processes, while Ni, Cr, Co, V, Sc, and Ba were derived from natural processes. Therefore, the contamination of Cd, Th, U, Pb, Zn, Cu, and Mn, especially Cd and Mn, should be considered by the environmental protection strategies in the studied watershed. Full article

Ultrasound waves have been widely used in the field of organic wastewater treatment due to their mechanical, thermal, and chemical effects derived from their cavitation effect. Many researchers have combined ultrasound waves with other organic wastewater treatment methods because they have the potential to offset the disadvantages of other methods. In recent years, many authors within the literature have reviewed the application of ultrasound combined with a certain wastewater treatment method. In this review, we introduce the working mechanism of ultrasound in the treatment of organic wastewater and then examine the synergistic effects of ultrasound with other organic wastewater treatment methods based on various applications, indicating a strong synergistic effect between ultrasound and other wastewater treatment methods. Subsequently, we introduce typical ultrasound-enhanced organic wastewater treatment equipment and propose some possible developmental directions for ultrasound in the treatment of organic wastewater.
