Abstract

The invention discloses a magnetic particle. The magnetic particle comprises a magnetic core and a porous shell coating the external of the core; the core is made of hydrocarbon oil, nanometer magnetic powder and a surfactant; and the shell is made of a photoinitiator, polyethylene glycol dimethacrylate, a pore forming agent and the surfactant. The invention also discloses a preparation method and an application of the magnetic particle. The magnetic particle is placed in sewage to separate oily pollutants from the sewage, and the filtered water is reused in industrial production.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a magnetic particle, a preparation method and an application thereof. Background technique [0002] With the rapid development of economy and society, water pollution has become an increasingly serious environmental problem. Water pollution is mainly caused by pollutants produced by human activities, including mine pollution sources, industrial pollution sources, agricultural pollution sources and domestic pollution sources. Water pollution affects industrial production, increases equipment corrosion, affects product quality, and even makes production impossible. Water pollution also affects people's lives, destroys ecology, and directly endangers people's health, causing great damage. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. Existing water treatme...
