▎ 摘　　要

NOVELTY - Micro-electrolytic filler comprises 40-50 wt.% iron powder, 20-30 wt.% activated carbon powder, 15-25 wt.% anaerobic sludge, 3-5 wt.% manganese powder, 0.1-0.5 wt.% graphene, 3-5 wt.% hydroxypropyl methylcellulose and 5 -8 wt.% sodium silicate. USE - Micro-electrolysis filler used for treating industrial waste water (claimed). ADVANTAGE - The micro-electrolytic filler preparation is simple and product has high strength, long service life, reduces heavy metal content and color of waste water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing microelectrolyte filler which involves: (A) adding iron powder, activated carbon powder, anaerobic sludge, manganese powder and graphene into water for obtaining semi-finished product A; (B) adding hydroxypropylmethyl cellulose and the sodium silicate to the semi-finished product A, and uniformly mixing to obtain the semi-finished product B; (C) providing spherical particles shape to the semi-finished product B, where particle diameter is 2-3cm; and (D) drying spherical particles at 100-120 degrees C for 8-10 hours, then performing calcination at 500-600 degrees C for 10-12 hours, then cooling to room temperature for obtaining finished product.
