Abstract

The invention discloses a sewage treatment agent for an oil production plant, belonging to the technical field of preparation of the sewage treatment agent. The sewage treatment agent for the oil production plant is prepared from the following raw materials in parts by weight: 40 to 80 parts of demulsifier, 30 to 60 parts of flocculant, 30 to 60 parts of foaming agent, 20 to 50 parts of flotation agent, 15 to 35 parts of fungicide, 10 to 20 parts of slow rot scale inhibitor, and 10 to 20 parts of deoxidant. The treatment agent provided by the invention for the oil production plant has the advantages of high deposition rate, good effluent quality, low treatment cost, no corrosive effect, nontoxicity, no pollution, safety in use, and the like; after oil production plant sewage is treated by adopting the treatment agent provided by the invention, the pH value basically reaches neutral pH, the SS removing rate can reach 99.09% to 99.27%, the COD removing rate can reach 99.02% to 99.11%, and the oil removing rate can reach 99.04% to 99.12%.

Description

【Technical field】 [0001] The invention relates to the technical field of preparation of sewage treatment agents, in particular to a sewage treatment agent for oil production plants. 【Background technique】 [0002] The chemical precipitation method is widely used in sewage treatment. It is to add some chemical agents to the waste water to make it chemically react with the pollutants in the waste water to form insoluble solid products, and then separate the solid and liquid to remove the water. A method of contamination. At present, in some industries, such as coal slime water, oil field wastewater, printing and dyeing wastewater, papermaking wastewater, etc., the chemicals used have poor treatment effects, slow sedimentation speed, high chemical costs, and some enterprises have caused serious corrosion of equipment. [0003] The produced water of the oil field oil production plant is extracted from the oil layer together with the crude oil. The wastewater not only carries cr...
