chemical oxygen demand

基本解释

Chemical oxygen demand discharges: 30.3 billion tonnes (44% from agriculture)
化学需氧量：303亿吨（44%来自农业）
Sulfur dioxide emissions and chemical oxygen demand kept falling, down 5.95% and 4.42% respectively, and this trend became more firmly set.
二氧化硫、化学需氧量排放量减少的势头得到巩固，全年分别下降5．95％和4．42％。
According to the study agriculture is responsible for 43.7% of the nation's chemical oxygen demand (the main measure of organic compounds in water) 67% of phosphorus and 57% of nitrogen discharges
研究表明，水质43.7%的化学需氧量（测量水质有机化合物的主要指标）、67%的含磷量和57%含氮量应归咎于农业。

China also missed its target for chemical oxygen demand, a measure of water pollution.

化学需氧量
As for water pollution,chemical oxygen demand（COD）is an important measure of organic pollution in water.
在水污染监测中,COD,即化学需氧量,是衡量水体有机污染的重要指标。
化学耗氧量
电气浮

化学需氧量
This fluctuation in the hydrogen yield was attributed to the formation of propionate. The rate of chemical oxygen demand (COD) removal reached 17%in the study.
化学需氧量(COD)的去除率最高达到66%,最后稳定在17%,。
