In addition, although the result of the dissolution test of clinker ash was shown in Table 4, there is almost no worry about water pollution.

The aragonite-like calcium carbonate used in the present invention is known as the Yoshida shell layer (Middle Pleistocene Pleistocene Ulm period) that is produced in Nishisata-cho, Kagoshima City, Kagoshima Prefecture (100,000 to 400,000 years ago) Sedimentary deposits), mainly clams such as bivalves. Unlike the hardly soluble calcium, this shell fossil is characterized by being easily eluted with aragonite calcium and having a porous surface.
Table 5 shows the chemical composition of the Yoshida shell fossil.

The porous soft silica used in the present invention is from Iwojima, Kagoshima Prefecture.
It is clear from the electron micrograph shown below that it is porous.
Measurements were taken at the Kagoshima Prefectural Industrial Technology Center.
The analyzer is a scanning electron microscope (JSM-840) / manufactured by JEOL Ltd. Observation conditions / acceleration voltage = 15 KV, 3 types of magnification (300 times, 1000 times, 3000 times)
The results are shown in FIGS. 6, 7A, 7B and 8.

  The results of chemical analysis of Iwojima silica are shown in Table 6. The analysis was performed by fluorescent X-ray analysis at the Kagoshima Prefectural Industrial Technology Center.

The work in the fermenter 102 is as follows.
(1) About seed meal, it is applied to rice (at the time of becoming 35-40 ° C) which cooked a commercially available koji mold hard, and uses it in a moromi state after about 24 hours. About 1 to 3 g of koji mold is added to 500 g of rice.
(2) About the initial seed soup input amount, input 1/500 as a guide for the solid content. Seeds are sprayed over the entire surface of the solids supplied to the fermenter.
(3) Next, ethanol solution, waste molasses solution and acetic acid solution are added to promote fermentation.
Waste molasses is 1/100 times the total volume of the 10-fold diluted solution.
Ethanol solution (60 degrees) is 1/100 of the total amount
For acetic acid solution (0.1%), 1/100 of the total is used as a guide.
(4) Stir twice in the morning and evening (5 minutes) and ferment at room temperature 30-35 ° C. for 4-5 days.
(5) The separated liquid part is returned to the solid-liquid separator 101. The settled solid (moromi) is sent to the next fermenter 102 and reused as seed potato. At this time, the ratio of solid: liquid is approximately 20:80.
The excess solid is taken out and used as fertilizer.

The staying days of the liquid in the storage tank 103 are about 3 days. While adding lactic acid bacteria and suppressing the occurrence of spoilage and malodor, microbubbles are sent to promote the decomposition or flotation separation and sedimentation separation of organic matter.
The retention time of the liquid in each filtration tank including the first to fourth (105, 107, 109, 111) and final filtration tank 113 is approximately 0.5 days. The liquid content residence days of the 1st microbubble crushing tank 106 and the adjustment tank 108 shall be about 1 day-1.5 days. The second microbubble crushing tank has a residence time of 2 to 4 days. The residence time of the liquid in the final adjustment tank 112 is about 1 to 1.5 days.

Table 7 shows the expected values and actual measured values at the time of planning for values such as BOD.
In Table 7, the literature values are the numerical values described in Table 2.

In Table 7, the water quality analysis results in the final adjustment tank 112 and the final filtration tank 113 are good values exceeding the plan, and it can be said that the treatment method for the shochu distiller of the present invention has provided excellent results. .
However, it can be seen that the analysis values in the first microbubble crushing tank 106, the adjustment tank 108, and the second microbubble crushing tank 110 are poorer than planned, and the fluctuation is large depending on the date and time. However, since sufficiently purified water can be discharged in the end, it is considered that the effect of the silica used as the last filter medium was great.
The BOD value of the storage tank 103 is 32,000 ppm for June 20 sampling and 78,000 ppm for August 3 sampling. At the time of June 20 sampling, the middle layer excluding floating solids and sedimented sludge In contrast, the transparent part of the sample was collected on August 3, but it was considered that the sample was obtained by stirring and mixing all layers as a sample.
In addition, the second microbubble crushing tank has a BOD of 15,000 ppm on both July 24 and August 3, because both floating solids and settled sludge are stirred and mixed with microbubbles. This is probably because of this.
