    • The present invention relates to a treatment system and a treatment method for recycling steel wastewater. More particularly, the present invention relates to a treatment method for recycling steel wastewater, comprising the steps of: lowering the pH of the steel wastewater by introducing the steel wastewater into a pH adjustment part; filtering the wastewater, which has been discharged from the pH adjustment part, by introducing the wastewater into a membrane filtration part; generating final process water by introducing the wastewater, which has been filtered by the membrane filtration part, into an RO filtration part; introducing concentrate into a concentrate treatment part via the RO filtration part, and discharging RO produced water for recycling; and evaporating the concentrate, which has been introduced into the concentrate treatment part, to combine the obtained steam with the produced water of the RO filtration part again.
    • 本发明涉及回收钢水废水的处理系统和处理方法。 更具体地说,本发明涉及一种回收钢铁废水的处理方法,包括以下步骤:通过将钢废水引入pH调节部分来降低钢水废水的pH值; 过滤从pH调节部件排出的废水,将废水引入膜过滤部分; 通过将由膜过滤部分过滤的废水引入RO过滤部分来产生最终工艺水; 通过RO过滤部分将浓缩物引入浓缩处理部分,并将RO排出水回收再循环; 并将已经被导入浓缩处理部的浓缩物蒸发,再次将得到的蒸汽与RO过滤部的生成水结合。

    • PURPOSE: A cyclone filter is provided to improve the filtering efficiency and remove ions and particles from a fluid. CONSTITUTION: A cyclone filter (1000) comprises a cyclone unit (100), an ion exchange fiber unit (300), and a conveyance unit (400). A fluid flows into the cyclone unit, and the particles contained in the fluid are separated by a centrifugal force and then discharged downwardly. The ion exchange fiber unit is coupled with an outer portion of the cyclone unit to filter fine particles and ions contained in the fluid passing through the cyclone unit. The conveyance unit is disposed between the cyclone unit and the ion exchange fiber unit to discharge the fluid, thereby preventing the decrease in the flow rate of the fluid passing through the ion exchange fiber unit.
    • 目的:提供旋风过滤器以提高过滤效率,并从流体中去除离子和颗粒。 构成:旋风过滤器(1000)包括旋风单元(100),离子交换纤维单元(300)和输送单元(400)。 流体流入旋风单元,并且流体中包含的颗粒被离心力分离,然后向下排出。 离子交换纤维单元与旋风单元的外部部分结合,以过滤包含在通过旋风单元的流体中的细颗粒和离子。 输送单元设置在旋风单元和离子交换纤维单元之间以排出流体,从而防止通过离子交换纤维单元的流体的流量的降低。

    • PURPOSE: A water-treatment apparatus and a water treatment method are provided to rapidly and accurately confirm a point of time for regenerating an ion-exchange resin. CONSTITUTION: A water-treatment apparatus(100) comprises a housing(110) in which a space is formed; a waste-water supply pipe(120); an ion-exchange resin(130); a waste-water discharge pipe(140); and a volume measuring part(150). The waste-water supply pipe supplies waste water to the space inside the housing through one side of the housing. The ion-exchange resin is located inside the space in the housing and removes treatment object ions from the waste water using an ion-exchanging method. The waste-water discharge pipe discharges the waste-water from which the treatment object ion is removed through another side of the housing. The volume measuring part measures a volume change of the ion-exchange resin and comprises a plate(152). A through-hole is formed in the plate for movement of the waste-water. When a value of the volume reaches a predetermined volume value, a regenerating material is injected into the space in the housing for the regeneration of the ion-exchange resin.
