The experiment results shown that: 1 the smaller the pH value, the smaller the use amount of alkaline metal and the alkali earth metal electrolyte demulsifier, when the pH value was 3, the waste fluid could be demulsified no any demulsifier and the use amount of the demulsifier did not increase remarkably along with the wiredrawing fluid concentration increased. 2 Using polymeric ferric sulfate as coagulant demulsifying, when the pH value was 8.4, the best adding amount was 40 mL per liter wastewater and the best precipitation time was 4 hours. Then the COD concentration was 480 mg/L, reaching the water quality requirements to enter the sewage treatment plant.
