PROBLEM TO BE SOLVED: To obtain a deodorizer to be used in various kinds of use, whose using method is simple with a high stability by forming it by means of a deodorizer stock solution with humic acid as an effective component, which is extracted from humic soil containing humic acid, etc. SOLUTION: Water obtained by adjusting pH to be about 7.6-8.5 by sodium bicorbonate in tap water from which chlorine is removed by an activated carbon, etc., or natural water from which a floating object is removed is put into a stainless steel-made tank 1 provided with a stainless steel lid. Water temp. is adjusted to be about 36 deg.C - about 40 deg.C so as to put humic soil in it. While stirring it by a mixer 9, it is exposed to air by air pumps 4 and 7, 8. Besides, in accordance with prescribed procedures, the deodorizer stock solution is filtered by way of heating and leaving. Activation is improved in the stock solution under the existence of an effective microorganism group in a dirty water tank, etc., so that the solution becomes the liquid deodorizer which indicates a deodorizing effect with humic acid as an effective component. When it is used in a spray, etc., in a garbage accumulating place, etc., for example, it is diluted by neutral water. Thus, it is used for various kinds of use with the stability. |
