[Claims]
(1)
Peroxide and nitrate ions having a peroxide concentration of 10% by weight or more and less than 50% by weight in terms of hydrogen peroxide in waste water, sludge, dewatered cake or washing water of a washing device containing a sulfur odorous substance. A deodorant method which comprises adding a deodorant containing the compound and a bactericide.
(2)
The deodorizing method according to claim 1, wherein the peroxide and the nitrate ion of the deodorant are represented by the formula (1).
