氧化降解含氮藥物及其對(duì)消毒副產(chǎn)物生成勢(shì)的影響研究摘要：氧化降解是一種強(qiáng)力的水處理方法，能夠降解水中的有機(jī)污染物和消毒副產(chǎn)物，其中含氮藥物是一種重要的有機(jī)污染物。本研究探討了氧化降解含氮藥物對(duì)消毒副產(chǎn)物生成勢(shì)的影響，并通過實(shí)驗(yàn)和模擬計(jì)算，揭示了不同條件下氧化降解過程中消毒副產(chǎn)物生成的規(guī)律與機(jī)制。結(jié)果表明，氧化劑種類、pH值、反應(yīng)時(shí)間、氯離子濃度等因素均對(duì)消毒副產(chǎn)物生成有明顯影響，同時(shí)含氮藥物的結(jié)構(gòu)和氧化降解產(chǎn)物的性質(zhì)也對(duì)消毒副產(chǎn)物的生成有關(guān)鍵作用。本研究結(jié)果為水處理過程中含氮藥物的處理及消毒副產(chǎn)物的控制提供了重要參考。
