Abstract

The invention discloses novel emulsion breaker for sewage treatment. The emulsion breaker is prepared from, by weight, 5-10 parts of an initiating agent, 3-5 parts of a polymer flocculation compound, 15-20 parts of sodium hydroxide, 5-10 parts of isobutyl alcohol, 3-5 parts of succinic acid, 8-15 parts of ethoxy polysilane and 5-10 parts of carboxymethylcellulose. The novel emulsion breaker for sewage treatment and a preparation method thereof are provided for overcoming the defect that existing emulsion breaker for sewage treatment is low in emulsion breaking effect.

Description

technical field [0001] The invention relates to the field of environmental protection. More specifically, the present invention relates to a novel demulsifier for sewage treatment and a preparation method thereof. Background technique [0002] Oily substances contained in oily wastewater include natural petroleum, petroleum products, tar and its fractions, and edible animal and vegetable oils and fats. In terms of pollution to water bodies, it is mainly oil and tar. Due to the great difference in the oil concentration in the wastewater discharged from different industrial sectors, such as the wastewater generated in the oil refining process, the oil content is about 150-1000mg / L, the tar content in the coking wastewater is about 500-800mg / L, and the wastewater discharged from the gas generation station The tar content can reach 2000-3000mg / L. Therefore, the treatment of oily wastewater should first use the grease trap to recover slick oil or heavy oil, the treatment effic...
