提高油气田废水中硫化物分析准确度的探讨

A DISCUSSION ON ENHANCING THE ANALYSIS ACCURACY OF THE SULFIDE IN THE WASTE WATER OF OIL-GAS FIELDS

从提高硫化物分析准确度入手,探讨了在复杂水样预处理过程中,如何消除基体干扰、控制pH值、防止硫化物损失,并对吹气装置做了一些改进,优化了操作条件,使硫化物回收率有显著提高,且设备简单、经济、操作方便。

Starting from enhancing the analysis accuracy of the sulfide in the waste water of oil-gas fields in the coures of pre-treating complex water sample,the problems of how to eliminate matrix disturbance,control pH value,avoid sulfide loss are discussed. Air blower is improved and its operating conditions are oplimized to make sulfide recovery ratio enhace remarkably.
