PURPOSE: A wastewater sludge fuel producing system is provided to reuse wastewater containing impurities discharged from a cleaning process of a dust collecting purification device. CONSTITUTION: A wastewater sludge fuel producing system comprises the following: a mixer(7) mixing 10~15wt% of wastewater sludge, 10~15wt% of waste lime powder, 30~35wt% of waste coal, 25~35wt% of food waste, and 5~10wt% of waste oil, after inserting 4~6wt% of seawater during a hot air receiving process; a pellet molding unit(8); a pellet arrangement device(9); first, second, and third drier(10,11,12); a fuel tank(13) storing dried pellets, and supplying the pellets for the combustion; a hot air and water boiler(14) for producing hot air and heating water; a dust collecting purification device(15) for purifying the gas discharged from the driers and the hot air and water boiler; a water purifier(16) for purifying wastewater; an ion exchanger(17) for sterilizing contaminants; and first and second substitution filtering absorption devices(18,19). |
