METHOD FOR WATER TREATMENT AND APPARATUS FOR WATER TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for water treatment and an apparatus for water treatment, which economically reduce an ammonia nitrogen concentration in raising water and improves cleaning of raising water of life and transparency of raising water of the life when water to be treated is raising water of the life.

SOLUTION: A raising water tank 1 is charged with raising water useful for raising life and micronanobubbles are generated from a micronanobubble generator 15 mounted in the raising water tank 1. Micronanobubble-containing raising water obtained by adding micronanobubbles to raising water is brought into contact with braid-shaped polyvinylidene chloride filling materials 20 and introduced into a filter. The micronanobubble-containing raising water passed from the filter is reintroduced into the raising water tank 1.
