密封法测定焦化厂废水COD_(Cr)值的研究

Study on determining value COD_(Cr) of wastewater in coking plants by sealing method

通过用密封法与回流法对焦化厂废水 CODCr的测定实验比较表明 ,密封法与回流法有很好的相关性。密封法应用于焦化废水的 CODCr测定中 ,具有可进行批量分析。

Determining value COD\-\{Cr\} of wastewater in coking plants by sealing and reflux method has shown that sealing method has a better correlation with r eflux one. When sealing method is applied to determining value COD Cr of wa stewat er in coking plants, it has the advantages of batch analysis and lower consumpti on of reagent, water and electricity.
