NOVELTY - A water treatment micro-filler comprises a porous micro-filler, a metal-based nano-type chemical material, and a nitrogen-based chemical agent in a mass ratio of 1:(0.0001-0.1):(0.001-1). USE - Water treatment micro-filler. ADVANTAGE - The water treatment micro-filler: effectively improves biomass and sedimentation of the biotank; retains relatively long generation period of denitrifying functional bacteria in a water treatment system; adjusts the structure of the flora and improves the autotrophic denitrification rate of the water treatment biosystem; and promotes energy saving and reduces consumption of reclaimed water plant by using the treatment agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the water treatment micro-filler, which involves uniformly mixing porous micro-filler, metal-based nano-type chemical material, and nitrogen-based chemical agent.
