“…However, due to their low removal efficiency, high treatment cost, and the production of secondary pollutants, considerable work remains to be done. The electrocatalytic oxidation technique is a multifunctional advanced oxidation processes (AOPs) which has been widely used in organic matter degradation treatments, for example in the treatment of phenol, antibiotic, and perfluorooctanoic acid containing wastewater [10][11][12]. The generated hydroxyl radicals (•OH) can realize the mineralization or decomposition of organic matter [13].…”

The efficient removal and kinetic modelling of methyl orange (MO) degradation using an electrocatalytic oxidation method in an activated carbon (AC) packed electrode reactor (ACPER) were conducted. A significantly high (81.2%) chemical oxygen demand (COD) and 100.0% MO decolorization efficiency were observed under the experimental conditions of current density of 3.0 mA·cm−2, flow velocity of 0.3 L·h−1, and treatment duration of 1.68 h using a β-PbO2/Ti anode. The high removal efficiency is ascribed to the anode expansion effect after AC packing. The anode expansion coefficient (λ) of the ACPER was calculated to be 0.63 from the cyclic voltammetry (CV) measurement, which means the further current utilization for MO oxidation. Based on the current utilization efficiency on anodic and particle electrode surfaces, a phase-reaction kinetics model was proposed for the simulation of MO COD removal efficiency. Our simulation results showed that the newly established average current efficiency (ACE) and energy consumption (Esp) model well matched the MO experimental degradation data. Our work broadens the scope of the application of ACPER in the treatment industry wastewater containing organics and provides a new strategy for the energy utilization evaluation during the removal of organic matter by electrocatalytic oxidation.

Freshwater shortages and water pollution have threatened the sustainable development of human beings. Efficient and sustainable technologies are urgently needed to achieve seawater desalination and wastewater treatment. Here, a hybrid device is developed consisting of photovoltaics (PV), membrane distillation (MD), and electrochemical advanced oxidation processes (EAOPs) for sustainable freshwater production and wastewater treatment. The device obtains freshwater from seawater with a stable rate of 0.97 kg m–2 h–1 under 1 sun, and the produced clean water reaches the drinking water limit of the WHO. This device also obtains freshwater from a methylene blue (MB) solution at a stable water production rate of 0.75 kg m–2 h–1, and the concentrated MB solution demonstrates a degradation rate of 96.05% by in situ degradation of EAOPs. The high water‐production performance and degradation performance is attributed to the well‐designed structure of the three stages PV‐MD‐EAOPs device, which enables both the latent heat recycle of water evaporation and the contaminants enrichment of wastewater. To summarize, a new path is explored for in situ thermal and electricity utilization of photovoltaic for efficient treatment of wastewater, which is a meaningful way for synchronous clean water production and wastewater treatment.

Petrochemical wastewater and produced water from oil and gas operations typically contain an array of organic and inorganic contaminants. The complexity of the wastewater, stringent environmental regulations, and the need for sustainable solutions have driven many research efforts in studying and developing advanced technology or combined treatment processes. On the other hand, the wastewater itself can be resources for water, energy, and other valuable product if appropriate technology is developed to recover them in a cost-effective fashion. The research advances in wastewater treatment and resource recovery technology are reviewed and summarized. For petrochemical wastewater, progresses were made in advanced oxidation, biological processes, and recovery of energy and water from wastewater. For produced water, many efforts were focused on membrane processes, combined systems, and biological treatment.
