HEAVY METAL WASTEWATER TREATING SYSTEM USING MEMBRANE SEPARATION-ION EXCHANGE, AND WASTEWATER TREATING METHOD USING SAME

The present invention relates to a heavy metal wastewater treating system using membrane separation-ion exchange, and a heavy metal wastewater treating method using the same, capable of improving removing performance of a pollutant by filtering a heavy metal hydroxide by using a membrane having 1-3 μm gaps without using a polymer coagulant; and adsorbing an ionic substance by exchanging filtered processing water with ions. The heavy metal wastewater treating method using membrane separation-ion exchange comprises: a raw water treatment step of forming the heavy metal hydroxide by preprocessing raw water including heavy metal (S100); a membrane separating step of filtering the raw water including the heavy metal hydroxide by using the membrane, and separating treated water, and concentration water of the raw water (S200); and an ion exchange step of absorbing the ionic substance included in the treated water through the membrane separating step (S300).
