Abstract

The invention provides a hollow nano-activated carbon rod and a preparation method thereof. The hollow nano-activated carbon rod is composed of 20-60 wt.% of 80-280-meshed attapulgite powder, 40-90 wt.% of 60-300-meshed activated carbon powder, and 30-75 wt.% of 200-600-meshed rubber powder. According to the hollow nano-activated carbon rod, the attapulgite powder, the activated carbon powder andthe rubber powder can achieve good synergistic effects; the rubber power contributes to bonding and shaping of the attapulgite powder and the activated carbon powder and further avoids falling powderor falling powder during application of the hollow nano-activated carbon rod and ensures high strength and hardness; meanwhile, the hollow nano-activated carbon rod can effectively inhibit bacteria breeding and is long in service life of COD (chemical oxygen demand) removal and environmentally friendly.

Description

technical field [0001] The invention relates to a filter material, in particular to a hollow nano activated carbon rod and a preparation method thereof. Background technique [0002] At present, the filter materials with activated carbon as the main raw material used for water treatment are easy to breed bacteria during the treatment process, have low COD capacity, short COD removal life, are easy to drop powder and fall apart during use, have low strength and hardness, and are not environmentally friendly. friendly.
