chemical oxygen demand(cod) meaning in Chinese
化学含氧量
Examples
- The quick determination technologies of chemical oxygen demand ( cod ) are summarized , and the applications of them are introduced
摘要文章介绍了化学需氧量( cod )的快速测定技术，以及在实际水质监测中的应用。 - This course demonstrate the important sorts of wastewater analysis , it includes chemical oxygen demand ( cod ) , biochemical oxygen demand ( bod ) , suspended solids ( ss ) , volatile suspended solids ( vss ) , ammonia nitrogen , organic nitrogen , nitrite nitrogen , nitrate nitrogen , orthophosphate , total phosphate , sulfate , and sulfide
本课程包含污水分析重要项目的原理解说及实验分析，分析项目包括：化学需氧量、生化需氧量、悬浮固体物、挥发性悬浮固体物、氨氮、有机氮、亚硝酸盐氮、硝酸盐氮、正磷酸盐、总磷、硫酸盐及硫化物。 - The experiments demonstrated that the removal of color and chemical oxygen demand ( cod ) and decolorization percentage is satisfying using pulse voltage waveform . moreover , the applications of pulse voltage waveform in the wastewater result in less power and electrode consumption than dc voltage , which reduces the cost
实验研究结果表明，与传统的直流电压波形相比，脉冲电压波形在取得满意的cod去除率和色度去除率的同时，节省可观的电耗和电极损耗，提高电能净化效率，降低污水处理的经济成本。 - Whereas being influenced by environment factors and influx material characters , urban rainwater is polluted in some degree and its content of chemical oxygen demand ( cod ) reaching thousands mg / l and containing some poisonous matter such as heavy metal etc . if this polluted rainwater is filled to ground , it must pollute groundwater
但由于城市环境因素和汇水面材料的影响，城区雨水受到相当程度的污染， cod可高达数千毫克每升，并含有重金属等有毒物质，如果将这些雨水直接回灌地下势必污染地下水源。
