Abstract

The invention relates to a preparation method of a multifunctional composite magnetic seed and an application of the multifunctional composite magnetic seed to a water treatment magnetic flocculationprocess, and belongs to the technical field of water treatment. Ferric iron salt, ferrous iron salt, activated carbon, polyvinyl alcohol, iron ore powder and sodium hydroxide serve as main raw materials, and the multifunctional composite magnetic seed is prepared by a co-precipitation method and applied to sewage and wastewater treatment. The multifunctional composite magnetic seed prepared by themethod is high in yield, simple to operate, low in cost, free from secondary pollution and high in reusability and has good removing effects on CODCr (chemical oxygen demand chromium), SS (suspendedmatters), TP (total protein), heavy metal ions and the like in wastewater.

Description

technical field [0001] The invention relates to a preparation method of a multifunctional composite magnetic seed and its application in the magnetic flocculation process of water treatment, belonging to the technical field of water treatment. Background technique [0002] Magnetic technology has developed rapidly since it was explored by experts and scholars at home and abroad in the 1970s and 1980s. It has achieved good results in the treatment of phenolic wastewater, heavy metal wastewater, dye wastewater, and radioactive wastewater, including magnetic separation and magnetic flocculation. , magnetic biology and other technical branches have formed a relatively complete theoretical system of process technology and magnetic technology. [0003] Magnetic separation technology refers to the selective separation of substances with different magnetic properties under the action of an external magnetic field force. It has the advantages of simple structure, small footprint, hig...
