A water treatment method according to the flocculant injection time is provided to minimize the consumption of an inorganic flocculant by promptly settling and removing sludge in a settling tank. A water treatment method according to the flocculant injection time comprises: degrading organic matters using microorganisms of an anaerobic tank or aeration tank and transferring treated water to a settling tank to settle sludge in the settling tank; transferring supernatant of the settling tank to a filter tank to filter residual suspended solids from the supernatant; injecting a flocculant into treated water flown into the settling tank from the anaerobic tank or aeration tank between a rear part(a treated water outlet) of the anaerobic tank or aeration tank and a front part(a treated water inlet) of the settling tank to chemically flocculate non-degraded organic matters in the treated water. |
