▎ 摘  要

NOVELTY - Digester comprises 10-20 wt.% nano titanium dioxide, 20-40 wt.% activated carbon, 5-10 wt.% nano ferroferric oxide, 5 10 wt.% silica gel, 0.5 1 wt.% silver composite, 5 10 wt.% graphene, 10 20 wt.% diatomaceous earth, 0.1-0.5 wt.% palladium, 1-5 wt.% reducing agent, 10-20 wt.% nano-calcium oxide. USE - Digester for micro-environmental pollution control. ADVANTAGE - The digester has low cost, reduces pollution and realizes rapid regeneration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing digester for micro-environmental pollution control, which involves: (A) adding nano titanium dioxide, nano ferroferric oxide, silver composite material, palladium chloride and reducing agent to dispersant solution, slurrying at stirring speed of 500-600 revolution/minute; (B) adding diatomaceous earth and silica gel, continue to stirring uniformly, spray-drying at temperature of 130-150 degrees C, mixing spray drying material with activated carbon, graphene and nano-calcium oxide, mixing uniformly; and (C) pressed to diameter of 10-20 and height of 0.3-0.6mm.
