Abstract
The invention relates to the technical field of water treatment materials, in particular to a preparation method of a ferromagnetic iron-based flocculant and efficient phosphorus removal application of the ferromagnetic iron-based flocculant. The preparation method of the ferromagnetic iron-based flocculant comprises the following steps: adding an iron salt solution into an oxalic acid solution, stirring until yellow precipitate appears, standing, and then sequentially carrying out suction filtration, washing and drying to obtain a ferrous oxalate precursor; and carrying out plasma treatment on the ferrous oxalate precursor to obtain the ferromagnetic iron-based flocculant. The invention provides the iron-based flocculant which is environment-friendly and efficiently synthesized at low temperature, is suitable for efficiently removing phosphorus in sewage and eutrophic water, and solves the problems of heavy pollution and low phosphorus removal efficiency in the traditional process.
