Abstract
Efficient treatment of viscous oil wastewater and oily residue is always a technical problem which puzzled the oil field management. To solve this problem, special chemical reagent is utilized to change the oily impurity contained in wastewater into coagulation through reaction of neutralization, demulsification, bridge formation, flocculation etc. Then through the physical method of compression, aeration, mixing evenly, rotational flow, release, floated by aeration，separation and blockage etc., the reaction between reagent and impurity is accelerated to let coagulation be separated to purify the water. Under the circumstance of above room temperature, reducing agent will be put into oily residue and be stirred sufficiently to let reducing reaction occur, separating the residue into petroleum and water with aluminum（iron）ion. The technique has achieved good result in terms of equipment efficiency, operation expense and condition after practice and explore of the last three years. Recycle and treatment of oil residue not only eliminate second pollution and complement the domestic technical deficiency but also achieve obvious environmental efficiency and economic benefit.关键词
