Special Issue Information

Dear Colleagues,

In recent years, advanced and novel wastewater treatment technologies have obtained increased attention. An increasing number of new technologies with better performance and new applications have recently been developed, such as physical, chemical, and biological techniques and advanced oxidation processes (AOPs). Consequently, the development of new environmentally friendly technologies that are able to quantitatively and quickly remove organic pollutants and recover resources in wastewater has become an extremely urgent challenge.

This Special Issue aims to collect original, high-quality articles related to wastewater treatment. Fundamental and applied research papers covering multidisciplinary topics, as well as review papers with new perspectives, will be considered.

The scope of interest:

  • Recent advances in wastewater treatment technology;
  • Development of novel chemical oxidation technologies involving ozone-, chlorine-, peroxide-, UV-, electro-, catalyst-, and Fenton-based chemical oxidation processes;
  • Evaluation of oxidation mechanisms involving (non-)radical species formation and utilisation;
  • Understanding of oxidation byproduct formation, toxicity evolution, and operation optimisation;
  • The synthesis and application of active catalysts for chemical oxidation treatments;
  • The combination of chemical oxidation with other physical adsorption/separation or biological treatments.

Refractory organic wastewater mainly includes wastewater from papermaking, textile, printing and dyeing, petrochemical, coking, pharmaceutical and other industries, as well as landfill leachate and its membrane-treated concentrate. The traditional biochemical method is difficult to adapt to its harsh conditions such as high toxicity, high organic load and high salinity. Compared to other methods, the electro-oxidation (EO) process owns the attractive characteristics of being clean and eco-friendly, highly efficient and producing no secondary pollution. EO systems mainly include electrodes, a reactor, a power supply and other basic units. The design of reactors with different electrodes was the key link in the application of EO technology. This paper mainly reported the different configurations of electrochemical reactors (ECRs) for refractory organic wastewater treatment, and summarized the advantages and disadvantages of them, including reactor structure, flow mode, operation mode and electrode construction. Compared with traditional reactors, the improved reactors such as 3D-ECR achieve higher mass transfer efficiency by increasing the contact area between the electrode and the fluid. Additionally, it has a higher removal rate of organics and a lower energy consumption. Finally, the future perspectives of the treatment of refractory organic wastewater by ECRs is discussed. This paper is expected to provide a reliable scientific basis for the real application of EO technology in refractory organic wastewater treatment. Full article
