气田水治理的初步研究

某些气田水溴含量高及COD高,本研究采用了曝气—混凝—氧化法降低COD以及离子交换法从气田水中直接制溴化钠的新工艺,并估算出了治理的成本与效益,为综合利用与治理气田水提供了一条经济的技术路线。

Preliminary Study on the Controll of Wastewater from Natural Gas Wells

A new technique, the processes of aeration--coagulation--oxidization is adopted to control the wastewater from natural gas weUs. Considering the high content of Br in the waste water, a new ion exchange technigue is used to directly extract Br and produce NaBr from the waste water. The preliminary estimation of the controlling cost shows a higher applied potentical of the technique for the control and comprehensive utlization of wastewater from natural gas wells economically.
