COD监测技术的发展及在生活污水处理中的运用

摘要

Chemical oxygen demand(COD) was an important parameter in the water quality monitoring,which reflected the extent of the water by reducing substances pollution.A brief comment on the most commonly used in monitoring methods and the development status of them was carried out.The applications of the methods in water treatment were made a short review.The advantages,disadvantages and trends of various methods as a conclusion,critical control factors of COD monitoring for sewage was representative of water samples as another.%化学需氧量（COD）是水质监测中的一个重要参数,它综合反映了水中受还原性物质污染的程度。文章对COD监测技术目前的常用方法、发展现状及其在生活污水处理中的应用做一简要评述,得出各种方法的优缺点及发展趋势和生活污水COD监测中的关键控制因素是水样的代表性这两个结论。
