Title: Disposal of dust collecting water discharged from steel making furnace
Inventor: FUKUDA TADASHI
IPC: C02F1/66
Filed: 1980-02-21
Abstract: PURPOSE: To neutralize a dust collecting water discharged from a steel making furnace in two steps using a waste acid.  
     CONSTITUTION: A dust collecting water discharged from a steel making furnace is introduced to the first reaction vessel provided with an air blowing pipe, where the water is mixed with a waste acid used for pickling steel articles to adjust the pH value of the solution at about 9 (8.5W9.5). The solution is then carried to the second reaction vessel provided with an air blowing pipe, where the same acid is added to the solution to adjust the pH value of the solution at about 7 (6.5W7.5). In the first step, divalent iron ions contained in the waste solution are oxidized to a trivalent state effective in formation of ferric hydroxide having a good precipitation ability, because the water is neutralized to an alkaline level of pH about 9. This first neutralization is also effective in reducing the concentration of iron ions which will remain in a reaction solution after neutralized in the second step. The oxidation reaction is completed by the neutralization in the second step to a sufficient extent. Consequently, the waste solution is separated to a sludge portion mainly composed of ferric hydroxide and a liquid portion whose iron ion concentration is lower than a permissible level for discharging waste water.
