High-activity three-dimensional particle electrode material for treating spraying wastewater and preparation method thereof

The invention provides a high-activity three-dimensional particle electrode material for treating spraying wastewater, which comprises 45-65 wt.% of powdered iron, 20-40 wt.% of activated carbon, 5-15 wt.% of a formula catalyst and 5-10 wt.% of an auxiliary material component. The high-activity three-dimensional particle electrode material is a sphere with a spherical honeycomb microporous structure, the diameter is 8-18 mm, and the resistivity at 20 DEG C is 20-200 m ohm.cm. Waste piezoelectric ceramics are pressed into fine powder of 200-400 meshes, the particle size is smaller, and the fine powder is basically in an amorphous state, so that the fine powder has higher surface activity, a nano-to-micron catalyst has a larger specific surface area, the electrochemical efficiency is effectively improved, the treatment effect is remarkably improved, the dispersity is better, and the fine powder is more easily and uniformly distributed in a final product. 本发明提供一种用于处理喷涂废水的高活性三维粒子电极材料，包括铁精粉(45～65wt.％)、活性炭(20～40wt.
