Research progresses in degradation of organic pollutants with calcium peroxide

With good stability,calcium peroxide （CaO₂） in water and soilcan gradually decompose to generate hydrogen peroxide （H₂O₂）,which is oxidant for oxidation reaction. CaO₂ has been used as a substitute for H₂O₂ in the field of environmental protection. The functional mechanism of CaO₂ is introduced. The research progresses of CaO₂ for treatment of wastewater containing halogenated substances,dyes,antibioticsand benzene series organics are reviewed.The research progresses of CaO₂ for treatment of contaminated soil containing petroleum hydrocarbons,polycyclic aromatic hydrocarbons,benzene series and pesticides are summarized. Future research directions are proposed：exploring the chemical-biological combination remediation technology by making full use of the characteristics of CaO₂ hydrolysis to generate O₂ and H₂O₂;exploring the combination of CaO₂ and other oxidants,to increase the applicability and economics of the CaO₂ remediation technology.
