The method comprises the following steps: introducing the comprehensive sewage of smelting into a wastewater regulatingtank to regulate a pH value of the sewage; then lifting the comprehensive sewage to a reduction reaction tank, adding a reducing agent, and carrying out a reduction reaction; after the reaction, introducing the comprehensive sewage into a coagulation reaction tank, adjusting the pH value of the comprehensive sewage to 7, then adding a heavy metal remover, and carrying out treatment; introducing the treated sewage into an inclined-tube sedimentation tank for flocculating settling, enabling the obtained supernatant to enter a clean water tank, and treating the obtained sludge for refining of heavy metals or other treatment; introducing the obtained supernatant into an LEC electro-catalytic oxidation device for degradation of organic pollutants, and discharging the sewage after the sewage reaches the standard. When the method is used for treating the comprehensive sewage, high efficiency and low cost are achieved, environmental protection is facilitated, and certain social benefits and economic benefits are achieved.
