Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a seeding agent using livestock manure as a raw material, a method for producing the same, a method for solidifying the seeding agent, and a solidified seeding agent. Here, the “seeding agent” is also called “seed agent” in the field of septic tank treatment, and means an effective microbial additive or chemical substance additive for promoting fermentation. The term "seeding agent" used in the present invention also includes those referred to as nutrition promoters, nutrients and the like.

2. Description of the Related Art In a septic tank, sewage treatment is performed using microorganisms and protozoa. In order to improve the treatment efficiency in such a septic tank, it is essential to adapt the biota in the tank to the inflow pollutants into the tank. In other words, it is important to add a large amount of biota corresponding to the pollutants flowing into the tank. However, the quality and the inflow amount of sewage flowing into the septic tank are generally not constant due to the fact that they differ for each household (that is, for each septic tank) or change over time. Therefore, there arises a problem that the biota in the septic tank deviates from the ideal state, and thereby the treatment efficiency decreases. In such a case or at the beginning of use of the septic tank, a seeding agent may be added to the septic tank in order to stabilize the biota in the septic tank quickly and effectively. As seeding agents, commercially available ones that use cultured microorganisms, ones that are made by mixing such microorganisms with sewer sludge and food residue sludge are commercially available.

[0003]

However, since the conventional seeding agent is liquid or powdery, the residence time in the septic tank is short and it is difficult to effectively use the seeding agent. . In particular, since the seeding agent is relatively expensive, the short residence time has been a serious defect. More specifically, even if a liquid or powdered seeding agent is put into the septic tank, if a large amount of sewage flows into the septic tank in a short time, the seeding agent does not come into sufficient contact with the sewage in the tank. As it is, it has flowed out of the tank, and there is a problem that the effect of the seeding agent can hardly be enjoyed. In particular, due to the recent revision of the Building Standards Law, the capacity of the septic tank has been reduced and the risk of the seeding agent flowing out has increased, so this problem has become apparent. Therefore, there is a strong need for a solid seeding agent to enable effective use of the seeding agent.

On the other hand, a large amount of livestock excrement discharged is conventionally used only as a compost, and a large amount of livestock excrement not used as a compost is drained or permeated underground, resulting in enormous cost. Some of the waste is treated as industrial waste. Further, livestock manure has a characteristic that it is difficult to be used for anything other than compost due to its high water content. Therefore, there is a social demand for applications that can make effective use of livestock excrement.

Therefore, in order to meet such demands, the present invention provides a seeding agent using livestock manure as a raw material, a method for producing the seeding agent, and an effective use of the seeding agent in order to realize the reuse of the livestock excrement. It is an object of the present invention to provide a method for solidifying a seeding agent and a solidified seeding agent so that the seeding agent can be solidified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the drawings. First, a method for producing a seeding agent using livestock manure as a raw material will be described. First, about 20 wt% to about 40 wt% sewage sludge, about 20 wt% to about 40 wt% livestock manure, about 0 wt% to about 5 wt% inoculum, about 0 wt% to about 5 wt%. Small fish and about 20 wt% to about 30 wt% of the water content adjusting agent are mixed and mixed by a mixing stirrer (for example, a maneuver spreader) (mixing step. In the present specification, all or a plurality of the above components are mixed. The mixture is called "raw material").

Here, the seed bacteria include seed compost obtained by fermenting compost, a commercially available microbial agent, and the like. What is a small fish?
It means non-sellable fish, fish bones, rough fish, etc. In addition, livestock manure includes cow manure, horse manure, chicken manure, sheep manure, and the like, and includes both feces only and a combination of feces and urine. As the water content adjusting material, not only wood waste but also sawdust, rice husk, waste wood waste, and the like are used.

Next, the raw materials are fermented for a predetermined time (primary fermentation step). At this time, the temperature of the raw material is a predetermined temperature (preferably about 50 ° C. to about 65 ° C., more preferably about 53 ° C. to about 57 ° C., most preferably about 55 ° C.).
Air is supplied to the raw materials so that oxygen is not deficient until C) is exceeded. The standard of the air supply amount is about 100 liter / m ³ / min. Then, when the temperature of the raw material becomes equal to or higher than the predetermined temperature, the air supply amount to the raw material is reduced to about (1
/ 10) to about (1/14). Note that the reduction of the air supply amount may be achieved by reducing the air amount per unit time, or may be achieved by intermittently supplying the air without reducing the air amount per unit time. Good. In the primary fermentation step, it is preferable to cut the raw material several times in order to make the fermentation uniform. The time required for the primary fermentation process is usually about 10 to 14 days. The water content of the raw materials in the primary fermentation process is 40%
Lower half to 50% lower half.

Then, when the temperature of the raw materials begins to drop,
The amount of air supplied to the raw materials is approximately (1 /
20) to ferment the raw material in a state of being reduced to about (1/30) (secondary fermentation step). In the secondary fermentation step, it is preferable to cut the raw materials several times in order to make the fermentation uniform. The time required in the secondary fermentation step is usually about 10 to 14 days. In the secondary fermentation process, the water content of the raw materials is in the high 30% range to low 40% range.

Then, the air supply is completely stopped and the raw materials are aged until the temperature of the raw materials reaches room temperature (finishing step). The time required for the finishing process is usually about 10 to 14 days. In the finishing process, the water content of raw materials is in the 20% range.

Next, the raw materials are set to 7 mm, 5 mm and 2 mm.
2mm sieve to make the product.
Used as the next raw material as seeds (sieving process).

In the above-mentioned example, a mixture of sewage sludge, livestock manure, inoculum, small fish, and a water adjusting material was used as a raw material, but about 50% to about 80% by weight of livestock manure,
A mixture of about 20% by weight to about 45% by weight of a water conditioner and about 0% by weight to about 5% by weight of an inoculum may be used as a raw material.

FIG. 1 is a table showing the results of tests conducted to verify the effectiveness of the seeding agent produced as described above. In FIG. 1, “Sample 1” uses sewage sludge, horse dung, cow dung, small fish, and moisture control material as raw materials, and “Sample 2” uses horse dung, cow dung, and moisture control material as raw materials, Sample 3 ”uses sewage sludge as a raw material, and a moisture conditioner. When the general viable cell count was measured for each sample, it was found that Sample 1 and Sample 2 in which the raw material contained livestock excrement showed a larger value than Sample 3 in which the livestock excrement was not included. It was Since the fact that the number of general viable bacteria is large is one of the indicators of whether or not it can be used as a seeding agent, the effectiveness of a seeding agent containing livestock excreta was demonstrated. Further, it is said that it is better that the seeding agent does not have high electric conductivity, and thus the effectiveness of the seeding agent containing livestock excrement can be seen from this point as well.

Next, a method for solidifying the seeding agent will be described. First, the raw material of the seeding agent is prepared. As the seeding agent, one obtained by the following method may be used, or one obtained from the livestock excrement as a raw material obtained as described above may be used. First, a water conditioner, an inoculum (for example, Bacillus), and one or both of sewage sludge are put into a container, and air is introduced from the bottom of the container for about 2 weeks to perform aerobic fermentation. At this time, in addition to the inoculum, the sewage sludge, and the water content adjusting material, livestock excrement or marine product waste (for example, starfish carcasses) may be added. By fermentation, the temperature in the container reaches about 60 ° C to 80 ° C, and the seeds contained in the sewage sludge die. The above process is called a primary fermentation process. As the water content adjusting material, wood waste, sawdust, rice husks, waste wood waste, and the like are used.

Ammonia gas and volatile organic acid are generated in the primary fermentation process. When exhaust gas is emitted to the outside, these gases are deodorized with a microbial deodorant or adsorbed on activated carbon for deodorization. The exhaust gas from the primary fermentation process has a raised temperature due to fermentation, but this exhaust gas is preferably used for the secondary fermentation process and / or finishing process described below.

Next, water is added to the seeding agent raw material that has been subjected to primary fermentation, and air is introduced from the bottom of the container for a couple of weeks to aerobically ferment to grow microorganisms. On this occasion,
The water content is adjusted so that the water content ratio is about 40% by weight to about 50% by weight. Due to fermentation, the temperature in the container is 50 ° C to 6 ° C.
It reaches about 0 ° C. The above process is called a secondary fermentation process.

Next, water is added to the seeding agent raw material that has been secondarily fermented, and air is introduced from the bottom of the container for about one week to perform aerobic fermentation to suppress the activation of microorganisms. At this time, the water content is adjusted so that the water content ratio is about 35% by weight to about 45% by weight. Due to fermentation, the temperature in the container is 15 °
It reaches about C to 25 ° C. The above process is called a finishing process.

The seeding agent obtained as described above is granular and has a water content of about 20% by weight to about 25%.
It becomes weight%.

The seeding agent obtained as described above is solidified. First, a binder is added to the granular seeding agent. As the binder, rice bran, rice flour, starch,
Alternatively, wheat flour (milling residue of cereals) is preferable. As a result of various experiments conducted by the present inventor, the amount of the binder added was about 1% by weight to about 30% with respect to 100 g of the seeding agent.
It has been found that preferably about 5% by weight, most preferably about 5% by weight. Addition amount of binder is 1% by weight
If it is less than, the seeding agent is hard to harden. On the other hand, when the amount of the binder added is 30% by weight or more, the BOD (biochemical oxygen demand) load in the tank increases, which is not preferable.

After adding a binder to the seeding agent and kneading, water is added to the seeding agent. The inventor
As a result of various experiments, it was found that the amount of water added is preferably about 5 ml to about 20 ml, and most preferably about 15 ml, per 100 g of the seeding agent. If the amount of water added is less than 10 milliliters, the seeding agent will be broken and will not solidify. On the other hand, when the amount of water added is 20 ml or more, the water content ratio becomes too large, and the seeding agent is apt to rot, which is not preferable.

The seeding agent added with the binder and water as described above is put in a mold as shown in FIG. A pressure device (not shown) is used to apply pressure to the seeding agent placed in the mold to solidify the seeding agent. As a result of various experiments, the present inventor has found that the pressure applied to the seeding agent is preferably about 0.5 kilogram to about 30 kilogram per square centimeter, and most preferably about 8 kilogram. Found out. If the pressure is less than 0.5 kg, the seeding agent will not set. On the other hand, when the pressure is 30 kg or more, the seeding agent becomes too hard due to the pressurization, and it becomes difficult to appropriately dissolve the seeding agent. The mold shown in FIG. 2 is merely an example, and molds having other shapes may be used.

Next, a method of arranging the solidified seeding agent 10 will be described with reference to FIG. In FIG. 3, 12 is a treated water tank, 14 is a backwash pipe, 16 is an air diffuser, 18 is a backwash air diffuser, 20 is a carrier, and 22 is a carrier outflow prevention net. As shown in FIG. 3, the solidified seeding agent 10 may be arranged on the carrier outflow prevention net 22 of the septic tank, or may be suspended from the carrier outflow prevention net 22 by using the hook member 24. Good. The seeding agent 10 solidified by the method of the present invention is used for 72 hours after it is placed in the septic tank (on average, about 72 hours later, the seeding agent in the seeding agent It is solidified to a hardness that completes the dissolution when the growth approaches the maximum value.

The present invention is not limited to the above-described embodiments of the invention, and various modifications can be made within the scope of the invention described in the claims, and they are also within the scope of the invention. Needless to say, it is included in.

[0050]

BEST MODE FOR CARRYING OUT THE INVENTION Next, a method for solidifying a seeding agent according to a preferred embodiment of the present invention will be described with reference to the drawings. First, the raw material of the seeding agent is prepared. As the seeding agent, one obtained by the following method may be used, or one obtained from livestock manure as a raw material may be used. First, a water conditioner, an inoculum (for example, Bacillus), and one or both of sewage sludge are put into a container, and air is introduced from the bottom of the container for about 2 weeks to perform aerobic fermentation. At this time, in addition to the inoculum, the sewage sludge, and the water content adjusting material, livestock excrement or marine product waste (for example, starfish carcasses) may be added. By fermentation, the temperature in the container reaches about 60 ° C to 80 ° C, and the seeds contained in the sewage sludge die. The above process is called a primary fermentation process. As the water content adjusting material, wood waste, sawdust, rice husks, waste wood waste, and the like are used.

Ammonia gas and volatile organic acid are generated in the primary fermentation step. When exhaust gas is released to the outside, these gases are deodorized with a microbial deodorant or adsorbed on activated carbon for deodorization. The exhaust gas from the primary fermentation process has a raised temperature due to fermentation, but this exhaust gas is preferably used for the secondary fermentation process and / or finishing process described below.

Next, water is added to the seeding agent raw material that has been subjected to primary fermentation, and air is introduced from the bottom of the container for a couple of weeks to aerobically ferment to grow microorganisms. On this occasion,
The water content is adjusted so that the water content ratio is about 40% by weight to about 50% by weight. Due to fermentation, the temperature in the container is 50 ° C to 6 ° C.
It reaches about 0 ° C. The above process is called a secondary fermentation process.

Next, water is added to the seeding agent raw material that has been secondarily fermented, and air is introduced from the bottom of the container for about one week to aerobically ferment to suppress the activation of microorganisms. At this time, the water content is adjusted so that the water content ratio is about 35% by weight to about 45% by weight. Due to fermentation, the temperature in the container is 15 °
It reaches about C to 25 ° C. The above process is called a finishing process.

The seeding agent obtained as described above is granular and has a water content of about 20% by weight to about 25%.
It becomes weight%.

The seeding agent obtained as described above is solidified. First, a binder is added to the granular seeding agent. As the binder, rice bran, rice flour, starch,
Alternatively, wheat flour (milling residue of cereals) is preferable. As a result of various experiments conducted by the present inventor, the amount of the binder added was about 1% by weight to about 30% with respect to 100 g of the seeding agent.
It has been found that preferably about 5% by weight, most preferably about 5% by weight. Addition amount of binder is 1% by weight
If it is less than, the seeding agent is hard to harden. On the other hand, when the amount of the binder added is 30% by weight or more, the BOD (biochemical oxygen demand) load in the tank increases, which is not preferable.

After adding a binder to the seeding agent and kneading, water is added to the seeding agent. The inventor
As a result of various experiments, it was found that the amount of water added is preferably about 5 ml to about 20 ml, and most preferably about 15 ml, per 100 g of the seeding agent. If the amount of water added is less than 10 milliliters, the seeding agent will be broken and will not solidify. On the other hand, when the amount of water added is 20 ml or more, the water content ratio becomes too large, and the seeding agent is apt to rot, which is not preferable.

The seeding agent added with the binder and water as described above is put in a mold as shown in FIG. A pressure device (not shown) is used to apply pressure to the seeding agent placed in the mold to solidify the seeding agent. As a result of various experiments, the present inventor has found that the pressure applied to the seeding agent is preferably about 0.5 kilogram to about 30 kilogram per square centimeter, and most preferably about 8 kilogram. Found out. If the pressure is less than 0.5 kg, the seeding agent will not set. On the other hand, when the pressure is 30 kg or more, the seeding agent becomes too hard due to the pressurization, and it becomes difficult to appropriately dissolve the seeding agent. The formwork shown in FIG. 3 is merely an example, and formwork having other shapes may be used.

Next, a method of arranging the solidified seeding agent 10 will be described with reference to FIG. In FIG. 4, 12 is a treated water tank, 14 is a backwash pipe, 16 is an air diffuser, 18 is a backwash air diffuser, 20 is a carrier, and 22 is a carrier outflow prevention net. The solidified seeding agent 10 may be placed on the carrier outflow prevention net 22 of the septic tank as shown in FIG. 4, or may be suspended from the carrier outflow prevention net 22 by using the hook member 24. Good. The seeding agent 10 solidified by the method of the present invention is used for 72 hours after it is placed in the septic tank (on average, about 72 hours later, the seeding agent in the seeding agent It is solidified to a hardness that completes the dissolution when the growth approaches the maximum value.

The present invention is not limited to the above-described embodiments of the invention, and various modifications can be made within the scope of the invention described in the claims, and they are also within the scope of the invention. Needless to say, it is included in.
