Effect of baking soda dry deacidification on total soluble salt in fly ash in waste incineration power generation industry
As is known to all, garbage incineration fly ash is the material collected in the heat recovery and utilization system and flue gas purification system after household garbage incineration. The yield of fly ash is related to the type of garbage, incineration conditions, incinerator type and flue gas treatment technology, and generally accounts for about 3%-5% of the total amount of garbage incineration. The analysis shows that the fly ash of waste incineration is not a chemically inert substance, which contains a high content of Cd, Pb, Zn, Cr and other harmful heavy metals and salts that can be leached by water. If not properly treated, it will cause heavy metal migration and pollute groundwater, soil and air.
