这张幻灯片概述了使用氯胺的信息以及由此产生的硝化问题。课程包括:硝化问题总结；导致硝化作用的水质条件；研究目标包括建立一个框架来理解 导致 使用中试规模的配水系统进行硝化，并使用全规模的饮用水配水系统验证框架；采用质量平衡法建立框架；试点研究研究方法；结果和讨论。

This slide presentation outlines information on using chloramines and the resulting problem with nitrification. Topics covered include: nitrification problem summary; water quality conditions that lead to nitrification; research objectives that include establishing a framework for understanding the water quality conditions that lead to nitrification using pilot-scale distribution systems, and verifying framework using full-scale drinking water distribution systems; establish framework using mass balance approach; pilot scale studies research approach; results and discussion.
