The objective of this project are to identify and quantify chemical reaction products when chlorine is used to disinfect wastewater treatment plant effluents. Special emphasis in this project is on reactions between nitrogenous organic compounds such as the amino acids and peptides in the effluents with chlorine. Spectral techniques are planned to be used for identification of the chlorination products, in the process of characterizing their stability and to determine how conventional methods of analysis respond to the presence of these compounds. Chlorination is relied on heavily in the United States for disinfection of effluents prior to their placement in environmental waters. Chlorine is known to react with organic compounds to form products many of which have not been fully characterized with respect to their environmental significance for downstream water users. Results of this project are expected to provide the basis for any changes that may be necessary in engineering design and use of chlorination to avoid or eliminate environmental problems associated with use of this process.

该项目的目标是识别和量化使用氯对废水处理厂废水进行消毒时的化学反应产物。 该项目特别关注废水中的氨基酸和肽等含氮有机化合物与氯之间的反应。 光谱技术计划用于鉴定氯化产物，表征其稳定性，并确定传统分析方法对这些化合物的存在有何反应。 在美国，污水在排入环境水域之前严重依赖氯化进行消毒。 众所周知，氯会与有机化合物反应形成产物，其中许多产物对于下游水用户的环境意义尚未得到充分表征。 该项目的结果预计将为工程设计和氯化使用中可能必要的任何改变提供基础，以避免或消除与使用该工艺相关的环境问题。
