摘　　要：采用高铁酸盐处理难降解有机物磺化酚醛树脂(SMP),研究了各影响因素对SMP的COD_(Cr)去除率的影响,确定了最佳条件,当SMP初始浓度为0.05%(质量分数)时,高铁酸盐投量为1.2g/L、反应体系pH为13、反应2h,SMP的COD_(Cr)去除率为79.4%。高铁酸盐的投量对SMP的COD_(Cr)去除率有很大的影响,不同浓度的SMP应当选择不同的高铁酸盐投量。絮凝作用对SMP的去除效果占总去除率一定比例,但SMP的去除仍以氧化作用为主。结合紫外-可见分光光度法(UV-Vis)、凝胶渗透色谱(GPC)和气相色谱-质谱联用(GC-MS)分析可以断定SMP分子结构中磺甲基结构基本完全降解,SMP的大分子主链发生断裂生成分子量为1300左右的带有苯环结构的物质,当主链降解到一定程度后,苯环结构开始被氧化发生开环反应,生成烃类小分子有机物,最终氧化成CO_(2)和H_(2)O。The refractory organic matter sulfonated phenolic resin(SMP)was treated with ferrate.The influences of various factors on the COD_(Cr) removal rate of SMP were studied.The optimal conditions were determined.When the initial concentration of SMP was 0.05%(mass ratio),the ferrate was 1.2g/L,the pH=13 and the reaction time was 2h,the COD_(Cr) removal rate of SMP was 79.4%.The amount of ferrate had a great influence on the COD_(Cr) removal rate.Different concentrations of SMP should choose different ferrate dosage.The removal rate of SMP was still dominated by oxidation and flocculation accounted for a low proportion of the total removal rate.Combined with UV-Vis,GPC and GC-MS analysis,it can be concluded that the sulphomethyl structure of SMP was completely degraded,and the macromolecular backbone of SMP was broken to generate substances with a molecular weight of about 1300 with a benzene ring.When the backbone was degraded to a certain degree,the benzene ring began to be oxidized and the ring-opening reaction occurred to form small molecular organic hydrocarbons,which were eventually oxidized to CO_(2) and H_(2)O.
