摘　　要：针对鄂东某区块高盐、高硬度、高化学需氧量(COD)以及高氨氮(NH_(3)-N)的深层煤岩气采出水在达标处理过程中COD与NH_(3)-N氧化降解难度大的问题,文章对芬顿氧化、臭氧催化氧化以及电解催化氧化三种氧化方法进行了探讨与分析,结果显示,电解催化氧化更适用于深层煤岩气采出水的氧化处理。通过本文研究可为深层煤岩气废水处理中氧化工艺的合理选择提供参考依据,助力相关领域的技术决策与实践应用。In view of the difficulty in oxidation and degradation of chemical oxygen demand(COD)and ammonia nitrogen(NH_(3)-N)in the water produced from deep coalbed gas with high salinity,high hardness,high COD and high NH_(3)-N in a certain block in eastern Hubei during the standard-reaching treatment process,this paper discusses and analyzes three oxidation methods:Fenton oxidation,ozone catalytic oxidation and electrolytic catalytic oxidation.The results show that ozone catalytic oxidation and Fenton oxidation only have a good effect on the removal of COD and their removal effects are similar.In terms of the removal of NH_(3)-N,Fenton oxidation and ozone catalytic oxidation have poor effects,while electrolytic catalytic oxidation has a good effect on the removal of both COD and NH_(3)-N.Therefore,electrolytic catalytic oxidation is more suitable for the oxidation treatment of water produced from deep coalbed gas.The research conclusions of this article can provide a reference basis for the rational selection of oxidation processes in the treatment of water produced from deep coalbed gas,and contribute to technical decision-making and practical applications in related fields.
