Abstract

The invention discloses a high-efficiency demulsifier. : 0.008‑0.015: 0.008‑0.015 mass ratio of the mixture. Excellent demulsification and water absorption when filtering high-concentration samples.

Description

【Technical field】 [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency demulsifier. 【Background technique】 [0002] The oil contained in sewage and domestic wastewater has always caused pollution to the environment, and the situation cannot be underestimated. With the development of the economy, my country has issued a series of testing standards for oil in water. The Montreal Environmental Protection Convention signed by Montreal, Canada stipulates that on January 1, 2019, my country officially abolished the standard for the extraction of oil in water with carbon tetrachloride as the extraction agent, and at the same time updated the extraction agent in the standard to tetrachloroethylene. , it is incidental that due to the chemical properties of tetrachloroethylene, serious emulsification of high-concentration oils is inevitable during the extraction process, and the new standard does not clearly mention that when emulsi...
