PROBLEM TO BE SOLVED: To provide a water treatment system capable of preparing, from seawater and accompanying water, injection water enabling oil drilling without abating the oil collecting efficiency while environmental protection is being taken into account.SOLUTION: The provided water treatment system is furnished with: a freshwater flow channel through which freshwater from a seawater desalinator 3 for obtaining freshwater by desalinating seawater is permeated; a treated water flow channel through which treated water from an oil-water separator 10 for obtaining treated water by removing the oil content included within accompanying water from an oil field is permeated; and an injection water preparation flow channel for preparing injection water to be injected into the oil field by merging the treated water permeated through the treated water flow channel and the freshwater permeated through the freshwater flow channel. |
