摘要:针对制浆造纸废水的复合仿酶深度处理技术，通过对复合仿酶处理前后的总有机碳(TOC)、Fe元素变化，对复合仿酶处理废水的反应产物与废水有机污染物凝胶渗透色谱（GPC）、气相色谱-质谱(GC-MS)、红外光谱图(IR)，以及对复合仿酶处理废水反应产物的X射线光电子能谱(XPS)的分析研究，明晰了复合仿酶处理体系对自由基反应的控制、引导和终止路径，揭示了“适度氧化-反应沉淀”的反应机理。

Abstract:The advanced treatment of pulp and paper wastewater was carried out by using composite biomimetic enzyme process. The changes of TOC and Fe element, the average molecular weight of reaction products in the wastewater after composite biomimetic enzyme treatment were investigated and the reaction products were analyzed by GC-MS, IR and XPS. The controlling, guiding and terminating paths of free radical reaction in composite biomimetic enzyme process were clarified, and the reaction mechanism of “modest oxide-reactive precipitation” was proposed.
