| abstract | Selenium contained in dechlorinated washing water of cement kiln bleed dust is treated to 0.1 mg / L or less which is less than or equal to the wastewater standard value according to the Water Pollution Control Law. The chlorine concentration in dust containing chlorine and selenium is measured, water is added to the dust to form a slurry, solid-liquid separation is performed, and the ferrous salt compound is supplied to the liquid phase after solid-liquid separation. In doing so, the supply amount of the ferrous salt compound is controlled in accordance with the measured chlorine concentration. It is preferable to adjust the pH of the liquid phase from 8 to 11 by supplying a pH adjuster when supplying the ferrous salt compound. After supplying the ferrous salt compound, solid-liquid separation is performed, and the ferric salt compound is supplied to the liquid phase after the solid-liquid separation.
