The present invention relates to a total preprocessing facility. More specifically, the total preprocessing facility includes: an inflow unit through which raw water flows in; a fine dust removing unit removing fine impurities contained in the raw water flowing in through the inflow unit; a sediment removing unit sinking and removing sediment contained in the water passing through the fine dust removing unit; an outflow unit from which the water where the sediment is removed flows out; an ultra-fine dust removing unit formed between the fine dust removing unit and the sediment removing unit and removing the ultra-fine impurities with a smaller particle size than the fine impurities; and an ultra-fine impurity removing unit formed between the sediment removing unit and the outflow unit and capable of removing ultra-fine impurities with a smaller particle size than the fine impurities. The total preprocessing facility can remove the impurities with a minimum particle size to reduce a load and a failure in a reaction treatment process at the rear end of a preprocessing facility and to improve reaction treatment efficiency. The total preprocessing facility can prevent the failure by reducing a load in a dust removing unit by minimizing an installation area and passing through the dust removing units in several steps. The total preprocessing facility also improves impurity removing efficiency. The sediment removing unit enables the sediment to sink by a settling tank wherein vortex is generated. Therefore, the total preprocessing facility improves sediment removing efficiency. |
