ABSTRACT:
A water treatment method and device can perform a regeneration treatment of the muddy water once used in a water excavation work to decrease its specific gravity for reuse in the water excavation work, and a dehydration treatment of various waste waters such as muddy water from the water excavation work and industrial waste water for final disposal.
The dehydration treatment includes a flocculating step for flocculating fine muddy particles, a solid-liquid separating step for separating the floccus to a solid part and a liquid part, a discharging step for discharging the liquid part through a filtering and water cleansing step, and a solid part treatment step for treating the solid part separated at the solid-liquid separating step, and the regeneration treatment including a solid-liquid separating step for separating the muddy water to a solid part and a liquid part and a reusing step for reusing the separated liquid part which is free from the muddy particles by the solid-liquid separating step, and a solid part treatment step for treating the solid part separated at the solid-liquid separating step.
The solid-liquid separating step is achieved by a centrifugal separator whose inner basket is composed of a non-perforated wall and a wheel shaped bottom.
