废水COD_(Cr)在线监测仪中硫酸汞的合理使用

The Rational Use of Mercuric Sulfate in Wastewater COD_(Cr) On-Line Monitoring Instrument

选取了当地三家安装北京环科CODCr在线监测仪的单位作为代表,进行了掩蔽剂硫酸汞使用量是否合理的实验。通过检测三家单位水样中的氯离子含量,得出了现行仪器中硫酸汞使用量偏高的结论。针对三家不同的单位,提出了硫酸汞的适宜用量;并对硫酸汞用量改变前后,进行了数据对比,实验表明降低硫酸汞用量是可行的。

Three local units that installed the CODCr on - line monitor instrument as representative, whether mercuric sulfate were reasonably use was tested. Through examined the chloride ion content in three units water samples, it got that in the present instrument, the mercuric sulfate amount of use were high, and the fair use of mercuric sulfate was proposed. To the comparison of the data that before and after, the experiment showed that it was feasible to reduce the amount of mercury sulfate.
