饮用水处理中常规氧化及紫外高级氧化强化除锰的研究进展
Research Progress of Conventional Oxidation and UV/AOP on Enhanced Manganese Removal in Drinking Water Treatment
摘要
Abstract
[Objective]Mn(Ⅱ)is a major cause of"yellow water"and discoloration in drinking water distribution systems.The development of efficient,stable,and controllable manganese removal processes has therefore become a critical issue in water supply engineering.This review systematically summarizes recent advances in the enhancement of manganese removal from drinking water by conventional oxidation and advanced oxidation process(AOP).[Methods]Relevant studies are reviewed to examine the application of conventional oxidants,including potassium permanganate(KMnO4),ozone(O3),sodium hypochlorite(NaClO),and chlorine dioxide(ClO2),as well as ultraviolet/AOP(UV/AOP),such as UV/hydrogen peroxide(UV/H2O2),UV/KMnO4,UV/O3,and UV/ClO2.The manganese removal performance,reaction mechanisms,and key influencing factors of these oxidation systems are comparatively analyzed.[Results]Conventional oxidation processes generally remove Mn(Ⅱ)through its oxidation to insoluble manganese oxides,followed by subsequent separation.The performance is strongly affected by oxidant dosage and pH conditions.Among these oxidants,KMnO4 and O3 are beneficial for promoting filter media maturation,whereas ClO2 is more suitable for controlling low to moderate manganese contamination.UV/AOP can markedly enhance Mn(Ⅱ)removal through the generation of reactive species to strengthen the oxidation process.In particular,UV/KMnO4 and UV/O3 have shown considerable potential for the treatment of medium-to high-mass concentration Mn(Ⅱ).However,these processes still face several challenges,including competition from organic matter,insufficient operational stability,and difficulties in by-product control.[Conclusion]Greater emphasis should be placed on source control,and manganese removal processes should be optimized in accordance with raw water Mn(Ⅱ)concentration,background water quality,and the risk of by-product formation.Future research should focus on elucidating the underlying reaction mechanisms,regulating interference from coexisting substances,and improving intelligent process operation,thereby promoting the development of manganese removal technologies toward higher efficiency,lower risk,and broader engineering applicability.关键词
