NEUTRALIZATION TREATMENT METHOD AND NEUTRALIZING AGENT |
摘要 |
Provided is a neutralization treatment method, whereby, in a neutralization treatment that is carried out for discharging a process solution generated in a metal refining process to the outside of a system, it becomes possible to reduce the amount of a neutralizing agent to be used, such as slaked lime, and to carry out the neutralization treatment with high efficiency. The neutralization treatment is carried out using, as a neutralizing agent for a solution discharged in the metal refining process, boiler ash which is produced after the combustion of a fluidized-bed boiler and which is produced by burning a sulfur content derived from coal, which is a fuel, while adding lime stone to the sulfur content and desulfurizing the sulfur content. |
