System for reducing environmental pollutants

The system for reducing environmental pollutants according to the present invention comprises: a first water immersion tank for producing strongly alkaline water by receiving a supply of bottom ash, which has been created by and has been accumulated at the bottom of a combustion furnace, and reacting it with water accommodated on its inside; an elimination reaction tank which is provided on a combustion pathway extending from the combustion furnace, and which internally accommodates the strongly alkaline water supplied from the first water immersion tank, and which also eliminates carbon-based compounds contained in exhaust gases which are discharged through the combustion pathway; a sludge-storage tank for receiving and storing sludge which has been produced as a consequence of the elimination reaction within the elimination reaction tank; a first aggregate storage tank for receiving and storing bottom-ash aggregate remaining within the first water immersion tank after the neutralization which follows as a consequence of the production of the strongly alkaline water; and a second water immersion tank for supplying the elimination reaction tank with strongly alkaline water which is produced by reacting water, accommodated on its inside, with a supply of fly ash which has been generated by the combustion furnace and has accumulated in a dust-collecting device on the combustion pathway.
