Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of preparing sodium hypochlorite which is drastically lower in a preparation cost than the technique in the prior art and a preparation facility for the same. SOLUTION: An aqueous solution essentially consisting of sodium chloride is formed by treating the hydrogen chloride in the waste gas evolved from a furnace for incinerating the material to be incinerated with a drug consisting of an alkaline compound, taking dust and/or the reaction production thereof out of the furnace and adding water thereto. The materials exclusive of the aqueous sodium chloride solution are classified and removed and further the impurities of the aqueous solution containing the sodium chloride are separated in an electrolytic cell 11 using an ion exchange membrane 12 and the aqueous solution is subjected to electrolytic treatment, by which the sodium hypochlorite is prepared.
