本powerpoint演示文稿首先简要概述了新出现的消毒副产品（DBPs）及其毒性。卤代硝基甲烷（HNM）形成的研究目标是:研究不同氧化剂和处理策略（O₃、Cl₂、O₃-Cl₂、NH₂Cl、O₃-NH₂Cl）的影响；调查溴和亚硝酸盐浓度的影响；研究pH值的影响。I-THM形成的目标是研究pH值（预成型的一氯胺）的影响；加氨前的预氯化接触时间（预氯化与预氯化一氯胺）；预氧化（KMnO₄、ClO₂、H₂O₂w/O UV）在预先添加一氯胺之前。实验方法包括:HNMs的形成电位测试- 在不同的饮用水源中添加过量的臭氧、氯、一氯胺、臭氧氯和臭氧一氯胺，消毒剂的剂量满足不同成分的不同水源的消毒剂需求，也满足NH₃和NO₂^-等部分成分的氧化剂需求；均匀形成条件（HNMs，I-THMs）-添加氯和一氯胺浓度，以在24小时后分别达到约1.0 mg/L和2.0 mg/L的消毒残留；并且，用MTBE提取萃取-I-THMs和HNMs，并用配备µ-ECD的气相色谱分析。介绍了氧化剂对HNM形成电位的影响，以及pH值（预氯化一氯胺）的影响，处理策略（预氯化和氨）的影响，以及- 预氧化（高锰酸钾、二氧化氯和过氧化氢）的影响。包括表格，数字。

This powerpoint presentation begins by providing a brief overview of emerging disinfection byproducts (DBPs) and their toxicity. Study objectives for Halonitromethane (HNM) formation were to: investigate the effects of different oxidants and treatment strategies (O₃, Cl₂, O₃-Cl₂, NH₂Cl, O₃-NH₂Cl); investigate the effects of bromide and nitrite concentrations; and, investigate the effect of pH. Objectives for I-THM formation were to investigate the effects of: pH (preformed monochloramine); prechlorination contact time prior to ammonia addition (prechlorination vs. preformed monochloramine); and, preoxidation (KMnO₄, ClO₂, and H₂O₂ w/o UV) prior to preformed monochloramine addition. The experimental approach included: formation potential tests of HNMs - excess amount of ozone, chlorine, monochloramine, ozone-chlorine and ozone-monochloramine were added to different drinking water sources, and the dose of the disinfectants satisfy the disinfectant demands for different water sources with different compositions and also satisfy the oxidant demands of some components such as NH₃ and NO₂^-; uniform formation conditions (HNMs, I-THMs) - chlorine and monochloramine concentrations were added to achieve disinfection residuals of approximately 1.0 mg/L and 2.0 mg/L, respectively, after 24 hours; and, extraction - I-THMs and HNMs were extracted with MTBE and analyzed with gas chromatography equipped with µ-ECD. The effect of oxidants on HNM formation potentials is presented, along with the effect of pH (preformed monochloramine), the effect of treatment strategy (prechlorination and ammonia vs - preformed monochloramine), and the effect of preoxidation (potassium permanganate, chlorine dioxide, and hydrogen peroxide). Includes table, figures.
