PURPOSE: A waste gas treatment system is provided to remove F, Cl, NO, SO, CO, H2S and dioxine in flue gas easily by aqueous NaOH solution and activated carbon. CONSTITUTION: In a waste gas treatment system where hazardous components in flue gas are removed through treatment tank filled with aqueous NaOH solution, the system comprises a cooler(21) installed at the bottom of a treatment tank(20) to cool the NaOH solution; a waste gas supply device(22) installed above the cooler(21) for supplying waste gas discharged from stack; more than two of NaOH spray plates(23) having a plural holes(23a) removably installed sequentially above the waste gas supply pipe(22), the holes(23a) being circular holes projected upward from the spraying plates by a fixed height; a sprayer(24) having many spray nozzles(24a) installed above the NaOH solution spray plates(23) for spraying NaOH solution; a dioxine adsorbing filter(25) of activated carbon set at the uppermost position.
