摘　　要：在油气田的开发过程中产生的气田废水,主要有硫化物、COD、Cl-、氨氮、SS、油等有害杂质,该类气田水如直接排放或者回注,可能导致污染地下水和土地资源环境。本文通过对该类废水进行化学沉淀、混凝、吹脱等方法获取多效蒸发原水,以及对多效分段蒸发脱盐的工艺研究,研究出了该类废水治理的工艺流程,实现了对气田废水的无害化综合治理和综合利用。The gas field waste water which is produced during the gas field＇ s development process mainly contains the following deleterious impurities： sulfide, COD, CI^-, Ammonia Nitrogen, SS and oil. It may pollute the underground water and land resources environment again if this kind of gas field water is emission and re-injection directly. According to the chemical precipitation, cocoagulating and blow-off of this kind of waste water to obtain multiple-effect evaporation raw water, and the technical research of desalted multiple-effect stage evaporation, this paper works out the technological process of the treatment of waste water. At the same time, this paper achieves the harmless comprehensive treatment and utilization of this gas field waste water.
