微生物消毒剂的应用是实现一次和二次消毒的必要条件。 不幸的是，大多数消毒剂与饮用水中的成分发生反应，形成不必要的消毒 副产品（DBPs）。这迫使许多公用事业公司优化其氯气剂量，或在生产中使用氯胺 分配系统。此外，一些工厂可能需要优化现有的处理工艺或 添加先进的处理技术来控制DBP。如果使用氯，这些方法将得到促进 在新的剂量和治疗条件下，氯胺衰变更容易预测。这项研究 开发了一些实用模型，预测不同剂量或不同剂量后的氯和氯胺衰变 基于单一消毒剂衰变研究和简单需求结果的不同处理工艺 在新的条件下进行测试。从三种不同的饮用水中收集了三种不同水质的水源水 处理厂。 到达时总有机碳（TOC）、溶解有机碳（DOC）、UVA254、pH碱度、硬度、浊度和 测量每种水的氨和溴浓度。 一部分水源用1微米的过滤器过滤，并留作原水 消毒。其余的水在分批混合槽中通过强化混凝处理 絮凝沉淀，然后用1微米过滤器过滤。这水的一部分被留作备用 成品强化凝固（EC）水。其余患者接受了进一步的临床试验 处理过程:活性炭吸附（GAC），臭氧氧化，然后 生物过滤（O₃/BF），或单独（仅O₃）和紫外线照射。按照指定的处理水 收集质量分析数据。对每个处理过的水测量TOC和UVA₂₅₄。此外 测量每种EC水的DOC、pH碱度、浊度和氨浓度。包括7个参考文献、表格、图表。

Application of microbial disinfectants is necessary to achieve primary and secondary disinfection. Unfortunately, most disinfectants react with constituents in drinking water to form unwanted disinfection byproducts (DBPs). This is forcing many utilities to optimize their chlorine doses or use chloramines in the distribution system. In addition, some plants may need to optimize existing treatment processes or add advanced treatment technologies to control DBPs. These approaches would be facilitated if chlorine and chloramine decay could be more easily predicted under new dose and tretment conditions. This study developed some practical models that predict chlorine and chloramine decay at different doses or after different treatment processes based on a single disinfectant decay study and results of a simple demand test at the new conditions. Three source waters with varying water quality were collected from three different drinking water treatment plants. Upon arrival total organic carbon (TOC), dissolved organic carbon (DOC), UVA254, pH alkalinity, hardness, turbidity, and ammonia and bromide concentration were measured for each water. A portion of the source water was filtered with a 1-micron filter and set aside for raw water disinfection. The rest of the water was treated in a batch-mixing tank by enhanced coagulation, tapered flocculation and settling, and then filtered with a 1-micron filter. A portion of this water was set aside as finished enhanced coagulated (EC) water. The rest was further treated with bench-scale advanced treatment processes: GAC adsorption (GAC), ozonation followed by biofiltration (O₃/BF), or alone (O₃ Only), and UV irradiation. Following the designated treatment water quality analysis data was collected. TOC and UVA₂₅₄ were measured for each treated water. In addition, DOC, pH alkalinity, turbidity, and ammonia concentration were measured for each EC water. Includes 7 references, tables, figures.
