It is put into the waste water of the grease trap device installed according to the allowable inflow flow rate and the standard intercepting grease amount shown in "1". The grease trap device shown in FIG. 1 has an inflow port 1 on the upstream side of the input layer T, and the waste water that has flowed in traps food residues in the basket 2 and then traps the waste water and the grease contained in the waste water. This is a system in which the partition plates 3, 4 and 5 block the waste water, and the waste water is discharged to the trap pipe 6 on the downstream side of the charging tank T. The volume of the charging tank T has been commercialized over various specifications depending on the amount of inflow and the amount of processing, and at present, a relatively large number of grease trap devices equipped with the charging tank T having a capacity of 60 to 3000 liters are manufactured or installed. Most of the devices adopt the same method as that shown in FIG. 1, regardless of the capacity.

Input so that it is in the range of%. The mechanism of odor reduction is due to the redox property of the phenolic structure of lignin contained in enucleated torula yeast due to its huge molecular structure (lignin sulfonic acid) and the intercalation (substitution ability) retained by synthetic mica.

るので、使用側の要求に併せた使用が出来る。Examples using the odor reducing material will be described below. [Example] As the odor reducing material, a kneaded and kneaded product composed of 99% of denuclearized Torula yeast and 1% of synthetic mica was used. The enucleated torula yeast used was a product name "Yeast B" manufactured by Nippon Paper Industries Co., Ltd., and the synthetic mica used was a product name "Somasif" manufactured by Coop Chemical Co., Ltd. For kitchen wastewater whose solid-liquid component consists of 98% water, the above mitigating material was put into a grease trap (volume specification of the input tank T of 100 liters) with an inflow rate of 100 liters / day and denuclearized Torula yeast (99%). Synthetic mica (1
%) 500 g (0.5% of the volume of the charging tank T) of the kneading-mixing odor reducing material was added to the drainage in a powder form. The drainage temperature was 25 ° C and the inflow PH was 6. After the lapse of 10 days from the introduction, a considerable amount of unpleasant odor such as ammonia was felt from the grease trap and the piping around it. However, after the lapse of 10 days from the introduction, the odor from the grease trap and its surroundings can be reduced, and the residual gas in the grease trap remains. The reduction of oil content was observed. This is a huge molecular structure (lignin sulfonic acid) with a structure made of lignin phenol contained in enucleated torula yeast.
It is the result that the redox property and the intercalation (substitution ability) of synthetic mica were exhibited. The ratio of enucleated torula yeast and synthetic mica is set to 1 to 15%, but in the case of 1 to 5%, 100 liters (daily dose) 5 to 10%, 100 to 500 liters (daily dose) 10 In the case of 15%, it is used in the range of 500 to 3000 liters (daily dose). This is because the inflow rate is fast, and the probability that the input amount stays in the wastewater decreases, and the original effect may not be exhibited in some cases. When the oil content (especially cup instant noodles) contained in the wastewater is 0.3 liters or more per day, it is necessary to decompose the odor generated from the oil content and the oil content attached to the drain trap. By increasing the input amount, the redox capacity and the substitution action of the odor reducing material can be promptly exerted, so that the odor reducing material can be used in accordance with the requirements of the user.
