Abstract

PROBLEM TO BE SOLVED: To provide a treatment process for organic industrial waste to convert it to a compost readily absorbable by plants that efficiently ferment organic industrial waste, so that the bad small from the waste is alleviated and removed and to provide substances to be user for converting the organic industrial waste to a compost. SOLUTION: An alkali mixture that contains a Ca-containing compound and a Mg-containing compound at a weight ratio of Ca/Mg of 3/1-10/1 is added to organic industrial waste in an amount of 0.1-2.5 wt.% and the mixture is subjected to fermentation treatment thereby converting to compost. During the compost treatment, K (potassium) in the fermentation system can be adjusted to 1/2 of Mg by weight by adding K. In addition, cellulose and/or lignin of wood such as sawdust or rice grain chaff may be added.

It is necessary to control the / N ratio, supply of water, oxygen, etc., but in general, the conditions for fermentation are too bad for the treatment of general organic industrial waste, and it is not an environment in which useful microorganisms grow. It doesn't work. In other words, in the case of general organic industrial waste, food processing residues, sludge, and animal dung often decay and give off odors. Does not always grow well. Therefore, at present, fermentation treatment using a useful microorganism cannot be successfully performed by itself.

【０００６】また、酸でミネラル類を溶解させて用いる

つＣａ及びＭｇがよい。The composting reaction of organic industrial waste is preferably neutral to weakly alkaline, and these pH ranges provide a favorable environment for actinomycetes and the like, in particular, decomposition of polysaccharides such as cellulose or decomposition of chitin. Is a good environment. Therefore, the fermentation treatment system is preferably Ca and Mg which are always kept from neutral to slightly alkaline.

So that it becomes 2. The amount of the composting material added is preferably 0.1 to 2.5% by weight based on the weight of the organic industrial waste, and if it is less than 0.1% by weight, the effect of the composting is significantly reduced.
If the content is more than 10% by weight, the cost and alkalinity increase, which is not preferable for the composting reaction. Preferably,
0.3 to 1.5% by weight is preferred.

As organic acid salts such as calcium hydroxide, calcium carbonate, calcium oxide, calcium sulfate, calcium acetate and calcium citrate; as magnesium, magnesium carbonate, magnesium hydroxide, magnesium oxide, magnesium sulfate, magnesium acetate and magnesium citrate, etc. Potassium nitrate, potassium dihydrogen phosphate and the like can be selected as the organic acid salt of K. For example, the solubility of calcium hydroxide and magnesium hydroxide in water is not large, and as the alkalinity is neutralized, calcium hydroxide and magnesium hydroxide further dissolve. It will not be rapidly dissolved and will be consumed depending on the reaction. Therefore, the treatment with alkalinity requires C 6 H in the decomposition of cellulose or the like in the composting reaction.
When CO 2 is generated by the reaction of 12 O 6 + O 2 → CO 2 + H 2 O, the neutralization reaction proceeds, and when an organic acid is generated, (C 6 H 12 O 6
→ CH 3 COCOOH), pH drop, pH 5
When it becomes below, the composting reaction is remarkably reduced, and the bond between cellulose and lignin in wood is adhered by hemicellulose, but since this hemicellulose is easily dissolved in alkali, it loosens this adhesion,
Since wood can be easily decomposed, it is convenient for composting woody materials such as sawdust or those containing a large amount of cellulose or lignin such as rice hulls.

By solubilizing minerals, it solubilizes minerals and acts as a catalyst for composting reactions. Therefore, under certain conditions, the form of an organic acid salt such as calcium acetate or calcium citrate or an organic acid salt such as magnesium acetate or magnesium citrate may be good.
