Abstract

The invention discloses a sewage treatment agent with an emulsion breaking effect as well as a preparation method and application thereof. The sewage treatment agent is prepared from the following raw materials in parts by weight: 27-35 parts of vermiculites, 11-19 parts of propargyl chloride, 4-8 parts of fumaric acid, 1-5 parts of methyl-tri-butanone-oxime silane and 19-27 parts of chitin. The preparation method comprises the following steps: crushing the vermiculites and mixing with a propargyl chloride solution; heating and stirring to obtain a mixture A; mixing and grinding the chitin and fumaric acid and carrying out ultrasonic treatment on the chitin and fumaric acid, and a mixed solution of the methyl-tri-butanone-oxime silane and water to prepare a mixture B; mixing the mixture A and the mixture B; and carrying out ultrasonic treatment, heating and calcining to obtain the sewage treatment agent. The sewage treatment agent has high temperature resistance; the oil removal rate and the efficiency of removing solid suspension matters are remarkably increased; and the sedimentation velocity is rapid, the feeding amount is less, the impact-resisting capability is high and corrosion on equipment is not caused. The sewage treatment agent has the advantages that a preparation process is simple, the production cost is low and the sewage treatment agent is suitable for industrialized production; and the sewage treatment agent has inverse demulsification and water purification effects and is especially suitable for purification treatment of thick oil high-temperature sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent with demulsification effect and its preparation method and application. Background technique [0002] The components of heavy oil high-temperature sewage in oilfield sewage are very complex: they contain solid impurities, microorganisms, dissolved gases and soluble salts and other components, and there are generally miscellaneous organic substances, high salinity, high oil content, and scale formation. Characterized by high ion content. There are many difficulties in the purification and treatment of heavy oil high-temperature sewage, mainly as follows: (1) The temperature of the discharged sewage is high, reaching 80-90 ° C, while the traditional treatment agent is broken at 80-90 ° C due to molecular chain breaks or oil and suspended matter molecules (2) A large amount of chemical agents need to be added during the process of lifting the produ...
