Treatment process and treatment device system for softened water extracted from gas field

The invention relates to a treatment process for softened water extracted from a gas field and a treatment device system thereof, and the treatment process comprises the following steps: introducing the softened water extracted from the gas field into a first-stage electrolysis device for electrolysis treatment, and then introducing the softened water into a second-stage electrolysis device for electrolysis treatment; the method comprises the following steps: adding hydrogen peroxide into water to remove hypochlorite ions, then adding sodium hydroxide to remove redundant hydrogen peroxide, then sequentially introducing the water into a high-pressure reverse osmosis device and a low-pressure reverse osmosis device for reverse osmosis treatment until the concentration of chloride ions in effluent is less than or equal to 100mg/L, and then introducing the water into an electron beam irradiation device for circulating irradiation, the treatment of the softened water extracted from the gas field is completed.
