The development of highly efficient and selective ozonation catalysts is crucial for enhancing the treatment of nitrogen-containing wastewater. In this study, a Co/Mg(OH) nano-hexagonal sheets ozonation catalyst was prepared by one-pot hydrothermal method, and the structural characteristics of this catalyst were comprehensively analyzed. The O/O ratio of this catalyst was 41.

Article Synopsis
  • A new treatment method called the intimately coupled catalytic ozonation and biodegradation (ICOB) reactor was developed to address the challenges of treating coking wastewater.
  • The ICOB system significantly improved the removal rates of contaminants like copper, iron, and color, outperforming traditional biodegradation methods.
  • It also boosted the presence of beneficial microorganisms that can break down harmful substances, leading to higher mineralization rates and reduced toxicity in the treated wastewater.

Article Synopsis
  • The development of O-dominated selective decontamination faced challenges due to excessive hydroxyl (HO) consumption and insufficient oxygen (O) generation.
  • A new approach was introduced that includes manipulating the spin state of iron (Fe) using nitrogen atoms, enhancing the efficiency of HO and oxygen generation under visible light.
  • The innovative system showed strong performance in diverse pH levels and resilience against various contaminants, paving the way for advanced water purification technologies.

Coking wastewater contains high concentrations of cyanide, phenols, pyridine, quinoline, and polycyclic aromatic hydrocarbons. Its high toxicity and low biodegradability leads to long hydraulic retention time of biological process and high cost of advanced oxidation process. In this study, the simultaneous combination of ozonation and biodegradation (SCOB) was proposed to treat coking wastewater.

In this study, a new intimately coupling technology of advanced oxidation and biodegradation was proposed, called simultaneous combination of ozonation and biodegradation (SCOB), which uses ozonation in place of traditional photocatalysis. SCOB was evaluated for its ability to degrade and detoxify tetracycline hydrochloride (TCH). Biodegradation alone only resulted in negligible TCH removal, while ozone alone caused less effective performance, with TCH degradation rate constants of 29-171% lower than those of SCOB.

Much attention has been paid on doping TiO to narrow its band gap to promote the absorption of visible light and restrain the recombination of electron-hole pairs to improve its efficiency in photoelectrocatalysis (PEC) under visible-light irradiation. However, the oxidation potential energy of photo-induced holes for the modified catalysts by visible-light excitation is lower than that without modification by UV excitation. In this work, we synthesized a co-coupled TiO electrode (denoted ERT) with the Er :YAlO and reduced graphene oxide (RGO), achieving the synergetic effect of visible-light-to-UV up-conversion and response and great electron transfer ability.
