耗氧污染物

鸭粪中含有大量氮、磷、微生物和耗氧污染物。

Duck dung contents a large quantity of nitrogen , phosphorus , microbe and oxygen consuming matter .

雨季中与雨季后富营养化指标对水质变异的影响最大，基本理化参数次之，耗氧污染物的影响最小。

During and after the rainy season , the eutrophication indexes have the maximum impacts on water quality variation , and then come basic physical and chemical parameters , aerobic pollutants have the minimum impacts .

对耗氧率和污染物去除率相关性分析发现，对于微污染水来说，溶氧并不是人工湿地污染物去除率的限制性因素。

From the relative analysis between oxygen consumption rate and removal rate of pollutants , we found that the DO is not the limited factor for wetland to remove pollutants of slightly polluted water .
