食品廃棄物の処理方法が提案されている。As one of the methods for treating such organic waste, Japanese Patent Laid-Open No. 6-116073 discloses that organic waste of humans or animals is treated with bio-aged corroded soil and larvae by the life activity of house flies of the species Synanthrops. It has been proposed to produce a biological substance (biomass), use the former as an organic fertilizer, and use the latter as animal feed.
JP-A-215785 proposes a method for treating food waste, in which organic waste such as livestock manure is inoculated with housefly (Musca domestica) eggs and treated with larvae to obtain biomass and digestion residues.

ると、消化残渣から蛹化の場所を求めて表面に這い出し
てくる。The method of treating organic waste by the life activity of these house flies is, for example, about 60 mm deep in a container designed so that odor does not leak outside.
× Wood about 5m × length about 20m, a tray-shaped processing tray called a dung disperser is arranged in multiple stages.
The thickness of the animal dung to be treated from the hopper arranged outside the container is sequentially transferred to the treatment tray by a pump with a thickness of 4 to 5c.
After feeding so as to be about m, the housefly inoculates with housefly eggs, and the room temperature varies depending on the season and the type and amount of organic waste to be treated.
When the temperature and humidity are kept at about 60 to 90%, it usually hatches in about 1 day, stays in the feces for about 4 to 5 days, digests and absorbs the feces with digestive enzymes, and decomposes the feces. When it is sterilized to generate a digestion residue and grows to a body length of about 5 to 8 mm, it crawls out on the surface in search of the place of pupation from the digestion residue.

る。Thus, unless the larvae crawling on the surface of the digestive residue are allowed to escape from the digestive residue, they become pupa in the digestive residue and it becomes difficult to use them as animal feed.
Both sides of the processing tray in the longitudinal direction are outwardly angled by about 2
When the larva escape slope is formed by inclining it about 0 degree and a larva housing box is placed below the front edge of this larva escape slope, the larva crawling on the surface in search of the place of pupation from the digestion residue Since the larva escape slope is climbed by itself, as a result, it falls down from the front edge and is accommodated in the larva accommodation box, which can be sterilized or used as a live feed.

率は実用化の点で隘路となっているものである。However, since the method for separating the digestive residue from the larvae by the self-escape of the larvae is based on the self-power of the larvae which can move only by the peristaltic movement, the larvae have a slope for larvae escape of the side plate. It is difficult to crawl well, and the above publication describes that collection is extremely easy. However, as will be described later, the recovery rate of feces is a bottleneck in terms of practical use.

As shown in FIG. 3, the side walls 3 and 3 facing each other in the longitudinal direction of the tray main body 2 having a shallow bottom are respectively inclined outward so that the upward slope is about 20 ° or less to form a larva escape slope. The side walls 4, 4 facing each other in the lateral direction are formed perpendicular to the bottom plate 2a.

する部位は一辺のみであってもよい。When forming the larva escape slope on the tray main body 2, it is necessary to incline each side plate integrally provided on the four circumferences of the bottom plate 2a to the outside at a predetermined angle to limit the larval crawling outlet. Since it is not ideal, in this case, it is not realistic to narrow the passage because the larva housing box has to be arranged on the four circumferences. Therefore, the side walls 3 and 3 which face each other in the longitudinal direction are formed on the edge of the bottom plate 2a. Although it is desirable to incline outward with respect to the base point so that the upward slope is about 20 ° or less, the site forming the larva escape slope may be only one side.

Are provided at a required interval on a rubber sheet member 5 having a relatively large frictional resistance. Are formed in parallel with each other, and the concave stripes 7, 7 ... Formed between the convex stripes 6 and 6 are used as escape paths for larvae, and the sheet member 5
The ridges 6 can be fixed to the larval escape slope surface in a state orthogonal to the longitudinal direction of the tray main body 2 to give the larva escape slope a rollover prevention function.

にすることもできる。In this case, the sheet member 5 may be attached to the entire surface of the larva escape slope, but as shown in FIG. 1, the digested residue produced by digesting and decomposing the contained organic waste. By sticking only on the surface position of, for example, the upper half position of the larva escape slope, the cost of the sheet member can be reduced and the sticking work can be facilitated. It is also possible to form a hook that engages with the leading edge of the side wall and to impart a rollover prevention function to the larva escape slope without adhering to facilitate replacement of the sheet member.

Are formed in parallel on the sheet member 5 with a required space, and the ridges 7 between the ridges 6, 6 are used to escape the larvae. When forming the path, the width of the concave streak portion 7 is about 2 to 5 mm in consideration of the body length of the larva, and the depth is preferably about 1 to 3 mm, but the width and the depth are not necessarily limited to the above numerical values.

For example, the surface of the side wall forming the slope for larva escape is harmless to larvae. After forming the adhesive layer, it can also be achieved by spraying synthetic resin so that the entire surface becomes uneven, in short, if the slope surface itself can be roughened to the extent that the larva can crawl by itself. Well, the degree of roughening can be set in consideration of the material of the side wall and the like.

く自力による脱出を可能とさせることが判明した。<Embodiment 3> Without using a sheet member attached to each larva escape slope surface of the stainless steel treatment tray in Embodiment 1, a paper file is used to roughen the entire surface, and then the treatment is performed. 25 kg of pig manure was placed in a tray for inoculation, and about 23.7 g of housefly (Musca domestica) eggs were inoculated, and the environment was maintained at a temperature of about 30 ° C and a humidity of about 70%. It started to crawl along the escape slope and fell into the larva collection box from the tip edge of the larva escape slope. The collected amount is 60g on the 4th day, 140g on the 5th day, and 1g on the 6th day.
20g, 640g on the 7th day, 0g on the 8th day, totaling 960
g were recovered. The recovery rate from feces was 4.1%.
This recovery rate against feces is extremely low compared to the above-mentioned examples, but due to the degree of surface sparseness of the slope, by making the surface sparser than that of a conventional wooden tray, it is possible to escape by itself without overturning. It turned out to be possible.

である。前記の結果を表１に示す。From the above results, in order to allow the hatched larvae to smoothly escape to the outside of the processing tray by themselves, if there is almost no frictional resistance on the larval escape slope surface on which the larvae climb, the anti-fecal recovery is performed. Although the rate is lower than that of conventional treatment trays, when using a larva escape slope that forms an escape route for larvae, the fecal recovery rate is dramatically doubled compared to conventional treatment trays. It has been found that this has improved, and when larvae escape by themselves, increasing the frictional resistance of the slope surface for larva escape is one of the important factors, but the important condition for escaping by themselves is to prevent rollover. It is clear that The results are shown in Table 1.

化することができる。In particular, the organic waste treatment tray of the present invention is used when a larva climbs the larva escape slope to a larva escape slope formed to facilitate escape of the larva from the treatment tray. Since a rollover prevention function was added to prevent the rollover that occurs in the larvae as much as possible, the larval recovery rate can be greatly improved and the larvae can be remarkably reduced from pupa in the digestive residue. Therefore, it is not necessary to provide a step of separating the composted organic waste and the biological material, and the organic waste can be easily and easily separated, so that the organic waste can be extremely efficiently composted.
