The invention of being related to a recovery and water treatment facilities and water treatment method using the same reduction is made in the sludge, the water treatment facility according to the present invention, O, sludge reduction means for reduction of the sludge discharged from a water treatment apparatus for treatment of waste water and, in the water treatment facility comprises a recovery means for recovering the received moisture in the sludge discharged from the water treatment apparatus and a reduction means, it said reduction means includes an alkaline agent in aqueous solution of sodium hydroxide in the sludge supplied from the water treatment device (1) this is the inlet through which the inlet to be mixed configuration, respectively, inside is equipped with blades which shred the cause solubilization with a mixed aqueous solution of sodium hydroxide sludge at a high speed, it characterized in that the discharge port for discharging the sludge, disrupted by the blade to the outside consists It shall be.
Therefore, the reduction due to the configuration of the water treatment device and the weight means due to the solubilization of the sludge consists of the enhanced digestion efficiency effect can be stably treated without the summer, the amount of waste water in the end to improve the treatment efficiency, which flows into the water treatment facility relationship the exercises.
In addition to the plan of the recycling to recover the efficiently due to the construction of the recovery means of reducing the load of the water treatment process while being to enable the added value is the effect that enables the effluent water quality.
