The present invention relates to a method for integrated treatment of
dyeing wastewater by using magnetic
activated carbon. According to the method, an improved magnetic
activated carbon adsorption process and an Fe3O4-H2O2 based Fenton-like technology are organically combined based on the preparation of a PAC-Fe3O4
composite material, and a
dyeing wastewater treatment technology integrated with adsorption and regeneration is proposed, and the materials after adsorption can be synchronously regenerated by using the Fenton-like technology in the
processing system. According to the method, the adsorption property of the PAC-Fe3O4
composite material and the Fe3O4 Fenton-like catalyst characteristic are fully used. At the time that the material performs
adsorption effect on the dye pollutants, H2O2 is synchronously added to form a Fe3O4-H2O2 Fenton-like
system to perform regeneration, so that the
processing ability of the
system is effectively improved, and the
processing cost is lowered. The advantages of a pure PAC process and a conventional Fenton process are organically combined, so that the shortages that the conventional PAC and the treated
wastewater are difficult to separate are easily to be lost, and cannot be regenerated are solved, and the problems that
ferric salt needs to be continuously added in the conventional Fenton process, and the
sludge output amount is large are improved. The method has the advantages of being simple, efficient, economical and the like, thereby having a large
potential market in
dyeing wastewater treatment applications.
