JP5788640B2 - Waste liquid treatment method - Google Patents

Description

  The present invention relates to a method for treating a waste liquid derived from food such as soy sauce cake.

  Conventionally, raw garbage from food factories and restaurants is outsourced to industrial waste disposal companies for incineration or disposal, and local government also incinerates raw garbage from each household. Most cases.

  When incinerating such garbage, fuel is required, and particularly when incinerating garbage containing a large amount of water, more fuel is required.

  For this reason, in recent years, taking into consideration the influence on the environment, attempts have been made to implement and reuse organic matter such as garbage by decomposing using microorganisms, composting and reusing.

  For example, the applicant installs a casing in which a water flow layer and an earthworm breeding layer are laminated in order on the rooftop of a building, and uses garbage generated from the building as food for earthworms on the earthworm raising layer of the casing. By spraying, it is proposed to digest raw garbage with earthworms, promote the decomposition of raw garbage by underground microorganisms with its excrement, compost the raw garbage and reuse it as soil for plant cultivation (For example, refer to Patent Document 1).

  On the other hand, when producing soy sauce, soy sauce cake containing a large amount of moisture is generated. In this case, attempts to use soy sauce cake as feed have also been proposed (see, for example, Patent Document 2), but most of them are dehydrated, and then the wastewater is diluted and dumped into rivers, and the residue is incinerated. ing.

  In addition, plum vinegar is generated when producing umeboshi, and shochu is produced when producing shochu. In addition, cooking oil waste oil is generated from each household. Such waste liquid derived from food is also almost discarded or incinerated.

  By the way, when making the soy sauce cake mentioned above into feed, it is necessary to process through various processes in a factory, and it is necessary to input much energy.

  It is also conceivable to compost food-derived wastewater using earthworms, but earthworms are aerobic animals, and if they are directly sprayed with food-derived wastewater whose water content is 90% or more, they become water-soaked. It ’s something that drowns and dies.

  The present invention has been made in view of such problems, and the waste liquid derived from food that has been incinerated or discarded so far is reused for organic fertilizer or the like by using earthworms without incineration or disposal. The present invention provides a method for treating waste liquid.

The present invention dries a wooden piece, bamboo piece or sawdust, absorbs the waste liquid derived from food into the dried wooden piece, bamboo piece or sawdust, and absorbs the waste liquid, the wooden piece, bamboo piece or sawdust, After forming the earthworm soil by mixing it with the breeding floor where the earthworms are cultivated, the earthworm soil is spread on the soil partitioned by the frame , and then the earthworm soil that has been spread is divided into multiple pieces. The food residue is regularly sprayed on each earthworm soil, and the food residue is digested by the earthworm, and the excrement promotes the activity of soil microorganisms. The soil microorganisms decompose the food residue and earthworm soil. The earthworm excrement is formed, and then the food residue is sprayed on only one half of the earthworm excrement in the frame. After laying earthworm soil on the other half of the soil, the food residue was sprayed only on the earthworm soil, and after a certain period of time, one half of the frame body was removed, and the earthworm soil was removed. In the other half of the earth, earthworm soil is spread again, and then the food residue is regularly sprayed on the divided earthworm soil in the frame in order, and the food residue and earthworm soil are decomposed to form earthworm feces. It is characterized by repeating the removal of earthworm dung.

  According to the present invention, earthworm nodule is prepared by spraying and mixing wood fragments or bamboo pieces or sawdust that have absorbed waste liquid derived from foods such as soy sauce cake, plum vinegar, shochu, and household waste oil on the earthworm floor. After creating the earthworm, spread the earthworm soil on the soil divided by the frame and spread it to a certain depth. Next, if the earthworm soil in the frame is divided into a plurality of parts, and the food residues are regularly sprayed on the divided earthworm cultures in order, the earthworms will remove the food residue that has been applied to the divided earthworm soils. It digests as food and excretes excreta. The excrement of earthworms activates the activities of soil microorganisms, so that the soil microorganisms decompose food residues and wood fragments that absorb the waste liquid derived from the earthworm nourishment. Then, the decomposed food residue and the wood fragments of the earthworm nourishment soil are digested again by the earthworm, and the excrement is excreted.

  In this way, by periodically spraying food residues in order on the divided earthworm soil, it is possible to spray food residues that match the amount of earthworms in the divided earthworm soil, and ensure that the food residues are digested. Can be made.

  Hereinafter, by repeatedly spraying food residues in order on the divided earthworm soil, food residues and wood fragments of earthworm soil are digested by earthworms and decomposed by soil microorganisms. After a certain period of time, it is converted into earthworm dung.

  If earthworm excrement is obtained, divide the earthworm excrement in the frame into two parts, spray food residue on only one half of it, take out the earthworm excrement in the other half after a certain period of time, and reuse it as organic fertilizer . Next, after the earthworm soil was spread on the other half of the earthworm excrement, the food residue was sprayed only on the earthworm soil. Arrange the earthworm soil again. In other words, earthworms have the property of sequentially moving to one side or the other side to which food residue as food is spread, so after a certain period of time, only the earthworm excrement on the other side or one side to which the earthworm has moved is harvested. be able to. Hereinafter, the food residue is regularly sprayed on the divided earthworm soils in the frame, the food residue and the earthworm soil are decomposed to form earthworm feces, and the earthworm feces are taken out.

  As a result, food waste that has been incinerated or disposed of so far and soy sauce cake, ume vinegar, shochu, and waste oil derived from foods such as household waste oil can be reused as organic fertilizer using earthworms without incineration or disposal. Can contribute to the prevention of global warming. Moreover, since thinned wood and abandoned bamboo forests can be used effectively at that time, satoyama can be maintained, and a new workplace can be created to revitalize the local community.

According to the present invention, it is possible to harvest only earthworm manure using earthworms without incinerating or discarding the waste liquid derived from food that has been incinerated or disposed of until now. Can be reused.

It is a perspective view explaining one Embodiment of the processing method of the waste liquid of this invention. It is the sectional view on the AA line of FIG. It is process drawing explaining the processing method of the waste liquid of this invention. It is process drawing explaining the processing method of the waste liquid of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show an embodiment of the waste liquid treatment method of the present invention.

  This treatment method is performed by arranging the frame body 2 on a field, a rice field, or abandoned cultivation ground, and spreading earthworm soil 3 in the frame body 2 to form the earthworm farm 1.

  Here, earthworm soil 3 mixes woody debris that absorbs waste liquids derived from foods such as soy sauce cake, ume vinegar, shochu, and household waste oil in the breeding floor such as humus that cultivates earthworms such as earthworm and red earthworm Formed.

  In addition, the wood fragments are obtained by cutting thinned wood and then crushing it into chips using a small crusher brought to the logging site. In this case, instead of the wood fragments, bamboo fragments obtained by crushing bamboo harvested in a stand bamboo forest and sawdust generated at a sawmill can be used.

  Such wood fragments are transported from the logging site to the earthworm farm 1 and then dried in the sun. Then, after the sun-dried wood fragments and the like are put into the pool, the waste fluid derived from food is absorbed into the dried wood fragments by spraying the waste fluid derived from food.

  Wood fragments or the like that have absorbed such food-derived waste liquids may be used as they are in the earthworm soil 3, or the wood fragments or the like may be dried again to absorb the food-derived waste liquid again.

  The earthworm soil 3 is kept at a suitable humidity for the earthworms to inhabit by spraying wood fragments, etc. that have absorbed the waste liquid derived from food, and mixing them to form the earthworm soil 3. be able to.

  When the earthworm soil 3 is sprayed and spread in the space defined by the frame body 2, the food residue 4 is sprayed on the earthworm soil 3 as food for earthworms.

  In this case, the frame 2 is preferably formed of wood in order to ensure air permeability. Further, the food residue 4 is preferably pulverized and sprayed from the viewpoint of promoting its decomposition, but is not necessarily pulverized. Furthermore, in order to prevent the occurrence of flies, it is preferable to prevent the exposure of the food residue 4 by spraying the earthworm soil 3 or the like on the sprayed food residue 4.

  When the food residue 4 is sprayed on the earthworm soil 3, the earthworm digests the food residue 4 as food and excretes excreta. And the excrement of earthworm promotes decomposition | disassembly of the food waste 4 and the waste wood derived from the food which comprises the earthworm nourishment 3 by activating the activity of soil microorganisms, and the decomposed food The food residue 4 and the wood fragments of the earthworm soil 3 are gradually decomposed by repeating the digestion and excretion of the residues 4 and the wood fragments of the earthworm culture 3 and the like.

  Hereinafter, the food residue 4 is regularly sprayed on the earthworm soil 3 so that the earthworm digests the food residue 4 and decomposes the soil microorganisms. After several months, earthworm soil 3 is converted to earthworm manure 5 (see FIG. 4 (a)). If the earthworm manure 5 is obtained in this way, the earthworm manure 5 can be taken out from the frame 2 and reused for organic fertilizer or the like.

  If the earthworm excrement 5 is taken out from the frame 2, the earthworm excrement 5 may be formed by laying the earthworm soil 3 again inside the frame 2 and supplying the food residue 4 repeatedly.

  As a result, there is no need to incinerate the food residue 3, and moreover, food-derived waste liquids that have been incinerated or discarded using a large amount of fuel, such as soy sauce cake, ume vinegar, household waste oil, Alternatively, shochu can be reused as organic fertilizer, soil improver, and deodorant with food residue 4 using thinned wood, abandoned bamboo forest, etc., which can contribute to the prevention of global warming. . It can also contribute to the elimination of thinned wood and abandoned bamboo forests and the effective use of abandoned farmland.

  An earthworm farm 1 as an embodiment of the present invention is formed by forming a frame 2 of 25 m in length, 5 m in width, and 0.7 m in height with wood and spreading earthworm soil 3 up to a height of 0.4 m in the inside. Is done. In this state, 50,000 earthworms live per cubic meter.

  Since earthworms dislike light, the earthworm farm 1 is usually covered with a frame 2 on the cold body. Moreover, the soil temperature is maintained at about 15 to 30 degrees except in the winter, and the treatment can be performed in the natural environment.

  The wood fragments constituting the earthworm soil 3 are those obtained by crushing thinned wood or the like to a particle size of 2 to 5 mm at the logging site, transporting them to the earthworm farm 1 and drying them in the sun. When the wood fragments are dried, after being sprayed on the pool, an amount of soy sauce cake corresponding to 90% of the volume is added, and the dried wood fragments absorb the soy sauce cake. Subsequently, the earthworm culture soil 3 is formed by throwing into the breeding floor 100 where the earthworm is cultivated and mixing the wood fragments into which the soy sauce cake is absorbed at a ratio of 30 to 50.

  On the other hand, the food residue 4 is pulverized by a pulverizer (not shown) and then sprayed on the earthworm soil 3 at different locations. Specifically, the inside of the frame body 2 is divided into seven parts, and the ground food residue 4 is crushed at about 1 ton per day every other day on the earthworm soil 3 of each divided section. Spray. (In FIG. 3, the earthworm farm 1 is divided into three parts for ease of explanation.) Hereinafter, the food residue 4 is dispersed by the earthworm by periodically spraying the food residue 4. Digested. In this case, earthworms are said to eat the same amount of organic matter as their weight per day.

  And when earthworm digests and excretes food residue 4, the activity of soil microorganisms is activated by the excrement, decomposes food residue 4, and decomposes wood fragments that have absorbed the soy sauce cake of earthworm soil 3 Let Moreover, it repeats that the earthworm digests and excretes the wooden fragments which absorbed the soy sauce cake of the food residue 4 and the earthworm soil 3 which were decomposed | disassembled.

  Hereinafter, by spraying the food residue 4 on the divided earthworm soil 3 periodically at different locations, the earthworm soil 3 becomes the earthworm excrement 5 (see FIG. 4 (a)) after 3 to 6 months. ).

  If the earthworm soil 3 in the frame body 2 is converted into earthworm excrement 5, the inside of the frame body 2 is divided into two parts, and the food residue 4 is supplied to only one half of the earth (see FIG. 4B). ). Thereby, since the earthworm of the other half part of the frame 2 moves to the one half part side with the food residue 4, the earthworm excrement 5 of the other half part side of the frame 2 can be harvested (FIG. 4 ( c)). Next, after the earthworm soil 3 is laid again on the other half of the frame 2 from which the earthworm excrement 5 has been taken out (see FIG. 4D), the earthworm soil 3 side that has been laid again, that is, the frame 2 The food residue 4 is spread | dispersed only to the other half part side, and the earthworm of the half part side of the frame 2 is moved to the other half part side (refer FIG.4 (e)). Similarly, after harvesting the earthworm excrement 5 on one half side of the frame 2 (see FIG. 4 (f)), the half part side of the frame 2 from which the earthworm excrement 5 has been taken out is spread with earthworm soil 3. The food residue 4 may be sprayed in turn on each divided earthworm culture 3 every day of the week.

  On the other hand, the harvested earthworm manure 5 is input to the farmland as a solid fertilizer, or liquid fertilizer is made using the earthworm manure 5 as a base material, and is input to the farmland or sprayed onto the crops.

  As a result, food waste 4 and soy sauce lees, which have been discarded and incinerated as wastes until now, are effectively used for the earthworm soil 3 of the earthworm farm 1 without being incinerated, and finally the earthworm manure 5 And can be returned to farmland as organic fertilizer to produce safe crops. In addition, it is possible to care for thinned wood and abandoned bamboo forests, to make effective use, and to make effective use of cultivated abandoned land.
