    • 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.
    • 水处理方法和装置可以在水开挖作业中使用一次使用的泥浆水进行再生处理,以降低其在开挖作业中的重力,再次利用水中的各种废水进行脱水处理 挖掘工程和工业废水进行最终处置。 脱水处理包括絮凝微细泥浆颗粒的絮凝步骤,用于将絮凝物分离成固体部分和液体部分的固液分离步骤,通过过滤和水清洗步骤排出液体部分的排出步骤,以及 用于处理在固液分离步骤分离的固体部分的固体部分处理步骤,以及包括用于将泥水分离成固体部分和液体部分的固液分离步骤的再生处理和重新使用分离的 通过固液分离工序不含泥浆颗粒的液体部分,以及用于处理在固液分离步骤分离的固体部分的固体部分处理步骤。 固液分离步骤通过离心分离器实现,其内篮由无孔壁和轮形底部组成。
