Description

  The present invention relates to a microorganism carrier used as a bed of aerobic bacteria and anaerobic bacteria in purification treatment of organic waste such as sewage and a method for producing the same.

  Inside the cedar, in order to spread the water sucked up from the roots to every corner, the water pipe is stretched like a thin blood vessel, and there is a cap everywhere in the water pipe, and this cap makes the cedar Does moisture adjustment.

  The cap of the water pipe has the property of closing when the cedar is cut. The number of closing is relatively large, about 160 per square centimeter. When such a cap is closed, moisture in the water pipe is trapped inside the cedar wood. Other general timbers other than cedar wood also have a cap in the middle of the water pipe, and the phenomenon of closing the cap by cutting and confining moisture due to this occurs.

  By the way, in general wood, the cap of the water pipe opens relatively easily by natural drying or treatment in a drying furnace, and the water in the water pipe easily escapes to the outside. On the other hand, cedar wood cannot be dried by natural drying similar to general wood because the cap does not open in the natural drying time similar to general wood. Even using a drying furnace, it is difficult to sufficiently dry cedar wood.

  Since cedar wood is relatively porous when its structure is examined, it can be used as a microorganism bed for purification of organic waste such as sewage. If the above-mentioned water pipe cap of cedar wood can be opened by some method, a porous structure composed of a large number of water pipes from which moisture has been removed is generated inside the cedar wood.

  For this reason, cedar wood after opening the cap has a significant increase in the percentage of porosity compared to cedar wood before opening the cap, resulting in a better microbial bed and purification of organic waste for the day. The amount of treatment can be increased, or a large amount of organic waste can be purified with a small amount of cedar wood.

  By the way, in patent document 1, the method of opening the cap of the water pipe of the cedar wood mentioned above is disclosed. In this method, cedar wood chips are processed at 100 to 150 ° C. in a furnace in which far infrared rays (5 to 20 μm) are generated (see paragraph 0006 in the document 1).

  However, even the method of Patent Document 1 described above reveals that it is difficult to open all the water pipe caps, and there are many closed caps. Since the water tube with the cap closed does not constitute a porous tissue, it is not used as a microbial bed, and is currently playing. If the closed cap can be opened, the percentage of the cedar wood will increase further, and it will become an even more excellent microbial bed, contributing to the improvement of the purification capacity per day. Alternatively, a larger amount of organic waste can be purified with a smaller amount of cedar wood.

  Patent Document 2 discloses an embodiment that includes cedar wood chips and mica ore that is a far-infrared emitting ore as an example of a constituent material of the sewage purification material (see paragraph 0014 in the same document 2). However, it is not disclosed that the mica ore is mixed in the heating stage of the cedar wood chip as in the present invention described later, and the mica ore in the document 2 is to open the cap of the water pipe of the cedar wood chip. It has not contributed.

[Outline of production method of microbial carrier]
FIG. 1 is an explanatory view of a method for producing a microbial carrier to which the present invention is applied. The method for producing the present microbial carrier shown in the figure is a method for producing a microbial carrier comprising a plurality of cedar wood chips, (1) a chip production process for producing a plurality of cedar wood chips, and (2) far-infrared radiation. An ore particle size adjusting step for adjusting the particle size of the ore, (3) a mixing step for mixing far-infrared radiation ore with adjusted particle size into the plurality of cedar wood chips, and (4) a plurality of particles containing far-infrared radiation ore. A heating step of heating the chip in a heating furnace, and (5) a removal step of obtaining a microbial carrier consisting only of a plurality of cedar wood chips by removing far-infrared radiation ore from the plurality of cedar wood chips after heating. , Including.

[Details of chip manufacturing process]
In the chip manufacturing process, using a well-known pulverizer or the like, cedar wood is crushed into small pieces to form chips, and a plurality of cedar wood chips are manufactured. As for cedar wood to be converted into chips, for example, branch portions of cedar wood that cannot be effectively used as furniture materials may be used. The average chip diameter of cedar wood chips is preferably in the range of 3 mm to 10 mm. The reason is as follows.

  The microbial carrier according to the present invention is produced using the cedar wood chip as a starting material, and is finally filled in a septic tank or the like, and used as a bed of aerobic bacteria and anaerobic bacteria. The average particle diameter of the microbial carrier during this use is substantially the same as the average chip diameter of the cedar wood chips. Therefore, when the average chip diameter of the cedar wood chips is smaller than 3 mm, clogging in the septic tank or the like is likely to occur. On the other hand, if the average chip diameter of the cedar wood chips is larger than 10 mm, the gap between the microbial carriers becomes too wide when filling the septic tank or the like, and it becomes difficult for the sewage to be purified to come into contact with the microbial carrier, Since the total surface area of all the microbial carriers filled in the container cannot be sufficiently secured, problems such as a reduction in purification ability occur.

[Details of ore particle size adjustment process]
In the ore particle size adjustment step, a mica ore having a maximum far infrared emissivity of 94% was prepared as an example of the far infrared radiation ore. The wavelength of infrared rays emitted from the mica ore is 10 μm to 100 μm. And the mica ore of a particle size larger than the average chip diameter of a cedar wood chip was produced by crushing the prepared mica ore. This is to facilitate removal of the mica ore in a subsequent removal step.

  In addition, instead of using mica ore, for example, quartz, bakuhanite, ceramic, etc. may be used as another far infrared radiation ore, or two or more kinds of far infrared radiation ore can be used in combination. .

[Details of mixing process]
In the mixing step, a predetermined amount of far-infrared radiation ore (grain mica ore in the present embodiment) whose particle size has been adjusted is mixed in a plurality of cedar wood chips, and these are mixed well. At this time, it is desirable that the far-infrared radiant ore whose particle size has been adjusted is uniformly dispersed in the plurality of cedar wood chips. This is because, with a uniform arrangement, it is possible to irradiate a plurality of cedar wood chips evenly with far infrared rays emitted from the far infrared radiation ore.

  The mixing of the plurality of cedar wood chips and the far-infrared radiation ore whose particle size has been adjusted may be performed in the wooden box K (see FIG. 2) or outside the wooden box K. When the mixing is finished, a plurality of cedar wood chips containing far-infrared radiation ore are put in a wooden box K and sent to the next heating step. In addition, although the wooden box K used here was a dimension of 400 mm x 400 mm x 400 mm, a wooden box larger or smaller than this can also be used.

[Details of heating process]
In the heating process, the heating furnace 1 of FIG. 2 in which far-infrared radiant ore is stuck on the inner wall surface of the furnace is prepared, and a plurality of cedar wood chips CH containing the far-infrared radiant ore 4 are placed in the heating furnace 1. In the present embodiment, since the plurality of cedar wood chips CH containing the far-infrared radiating ore 4 are accommodated in the wooden box K as described above, the plurality of cedar wood chips CH containing the far-infrared radiating ore 4 are stored in the wooden box. It is placed on the shelf 5 in the heating furnace 1 while being put in K. A plurality of wood chips CH containing the far-infrared radiating ore 4 can be placed directly in the heating furnace 1 without being put in the wooden box K.

  The heating furnace 1 is an electric furnace in which the entire inner surface of the furnace outer wall material 2 is covered with a refractory brick 3 as shown in FIG. 2 and a far infrared radiation ore 4 is stuck on the inner surface of the refractory brick 3. Has a plurality of shelves 5 on which wooden boxes K are placed.

  In addition, since this heating furnace 1 assumes that an operator enters in a furnace in order to put the wooden box K on the shelf 5, the far-infrared radiation ore 4 is not stuck on the floor surface of the heating furnace 1. However, if a configuration such as placing the wooden box K on the shelf 5 in the furnace by remote control is adopted, the far-infrared radiation ore may be stuck on the floor surface of the heating furnace 1.

  For the far-infrared radiant ore 4 to be attached to the inner wall surface of the heating furnace 1, mica ore having a maximum far-infrared emissivity of 94% was used. Quartz, bakuhanite, ceramic, etc. described in (1) may be used.

  In this heating step, the furnace temperature of the heating furnace 1 was set in the range of 80 ° C. to 140 ° C., and the heating time was set in the range of 24 hours to 48 hours. Thereby, far-infrared radiation is emitted from both the far-infrared radiation ore 4 on the inner wall surface of the furnace and the far-infrared radiation ore 4 mixed in the plurality of cedar wood chips CH. The plurality of cedar wood chips CH in 3 are heated from inside and outside of the wooden box 3 as indicated by arrows A and B in FIG.

[Details of removal process]
In the removal step, the far-infrared radiation ore 4 is removed from the plurality of cedar wood chips CH after the heating, and this removal operation can be easily performed using a sieve or the like. This is because the particle diameter of the far-infrared radiation ore 4 is adjusted to be larger than the average chip diameter of the plurality of cedar wood chips CH. About the removed far-infrared radiation ore, you may send it to the mixing process demonstrated previously, and may reuse it. A plurality of cedar wood chips from which far-infrared radiation ore has been removed are packaged and shipped as a final product.

  In the method for producing a microorganism carrier according to the present embodiment described above, far infrared radiation ore 4 is mixed in a plurality of cedar wood chips CH, and a plurality of cedar wood chips CH containing the far infrared radiation ore 4 are mixed in the heating furnace 1. A far infrared ray A emitted from the far infrared radiation ore 4 on the inner wall surface of the heating furnace 1, and a far infrared ray B emitted from the far infrared radiation ore 4 mixed in the plurality of cedar wood chips CH, In both cases, a method of heating a plurality of cedar wood chips CH from inside and outside is adopted. For this reason, the heating efficiency of the cedar wood chip CH by the far infrared rays A and B in the heating furnace 1 is increased, and the cap CAP (see FIG. 3C) of the water pipe P of the cedar wood chip CH is shown in FIG. As shown in b), it succeeded in opening more than the conventional method.

  Thus, according to the microorganism carrier comprising a plurality of cedar wood chips obtained by the manufacturing method of the present embodiment, the water pipe of cedar wood that has been played without being used as a microbial bed as in the past, that is, cap CAP Since the number of closed water pipes P is greatly reduced (see FIGS. 3 (a) and 3 (b)), and the porous structure of the cedar wood is further promoted, the number of aerobic and anaerobic fungi increases, The purification processing capacity per day can be improved, or a large amount of organic waste can be purified with a smaller amount of cedar wood, and the purification processing facility can be made compact.

  When the purification capacity of sewage using a microbial carrier composed of cedar wood chips is shown by specific numerical values in relation to the daily treatment amount of sewage, it consists of cedar wood chips whose cap is opened by the method of Patent Document 1. When the microbial carrier was used, it was necessary to fill the septic tank with an amount of microbial carrier corresponding to about 400% of the daily treatment amount of sewage. On the other hand, when a microbial carrier made of cedar wood chips obtained by the production method of the present embodiment is used, the septic tank can be filled with an amount of microbial carrier equivalent to about 30% of the daily treatment amount of sewage. As a result, the capacity of the microbial carrier necessary for the treatment of sewage in one day could be greatly reduced.

  In FIGS. 3 (a) and 3 (b), the aerobic bacteria mainly propagate because the porous holes constituting the cedar wood chip CH, that is, the vicinity of the inlet P1 of the water pipe P from which moisture has escaped, contact with air. In the vicinity of the hole P2, it is difficult for air to enter, so anaerobic bacteria mainly propagate, and in the vicinity of the hole outlet P3, both aerobic and anaerobic fungi are generated.

  Cedar wood contains chemical components such as lignin and pentosan, and when they come into contact with water, the red pigment flows out by a chemical reaction. However, according to the manufacturing method of this embodiment, the pigment does not easily flow out. It became clear that
