The invention relates to an iron-manganese-boron porous microsphere catalyst, which comprises MnFe 2 O 4 , Fe 2 O 3 , FeBO 3 , B 2 O 3 and trace carbon; wherein, MnFe 2 O 4 and Fe 2 O 3 are catalysts Active component, B 2 O 3 is a skeleton component, FeBO 3 is both a catalytically active component and a skeleton component, and the mass percentage of the catalytic active component in the catalyst is 80-95%; B 2 O 3 is used as a binder, polyethylene Alcohol is used as foaming agent, and iron - manganese powder catalyst is used as functional component, which is obtained by high temperature calcination. The respective catalytic properties of MnFe 2 O 4 , Fe 2 O 3 and their synergistic catalytic effect can better improve the production of OH in the reaction process, the removal efficiency of COD, chroma, organic nitrogen and organic phosphorus is high, and the degradation product molecules are more efficient. Small, more easily biodegradable, low concentration of iron ions in effluent, low cost, high catalyst hardness, strong erosion resistance, no hardening and no damage, low catalyst dissolution, excellent stability and long service life. |
