Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compost / liquid fertilization method for regenerating solid organic waste such as feces and garbage and liquid organic waste such as urine as fertilizer.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. 57-10658
As disclosed in No. 8, after receiving organic waste such as manure into a treatment plant, in this treatment plant, organic waste such as rice husks and sawdust is used as a modifier for moisture adjustment. To reduce the water content of the organic waste, and then heat-dry the mixture until the water content becomes 10 to 20%, so that manure and the like are composted. Are known.

[0003] There is also a method of composting organic waste such as garbage generated in large quantities at home (Japanese Patent Laid-Open No. SHO 52-52).
-31573 gazette). In this method, after receiving organic waste such as garbage into a treatment plant, the water content of the organic waste is reduced to an optimum value (for example, about 60%) at the treatment plant, and the water content is reduced to an optimum value. The resulting organic waste is put into a fermenter or the like for several days, aerobic fermented by aerobic fermenting bacteria, and then aged, so that garbage and the like are composted.

[0004]

However, in the method for composting organic waste such as manure and garbage, temperature is an important factor. That is, apart from the former, the temperature of which is increased by heating, apart from the latter, aerobic fermentation by aerobic fermentation bacteria, because organic waste contains a large amount of water, In the fermenter, the temperature does not rise to a temperature required for aerobic fermentation (for example, 60 ° C.), which is a factor that delays fermentation degradation by aerobic fermentation bacteria.

[0005] Therefore, in particular, when an organic waste including manure and the like is subjected to aerobic fermentation by aerobic fermenting bacteria, the fermentation decomposition by the aerobic fermenting bacteria is delayed by urine in which almost 100% becomes water, and the A bad odor is generated over the entire area.

Therefore, organic waste containing only feces, excluding urine, is used as a raw material for compost, and the water content of solid organic waste not containing urine is kept low in advance. While enabling the temperature rise of organic waste in the fermenter to promote fermentative decomposition by aerobic fermenting bacteria,
It is conceivable to suppress malodor generated over a long period due to urine in a short period of time.

However, during the process from fermentation to aging of solid organic waste such as feces and garbage, the solid organic waste after fermentation has insufficient water content. Water must be supplied to the solid organic waste in preparation for ripening after fermentation, and fresh water is prepared to eliminate moisture from urine. There is a need.

In this case, it is conceivable to use liquid organic waste such as urine as conditioning water. However, when urine is directly added to solid organic waste deodorized by fermentation decomposition, solid organic waste is used. Odor is generated again from the system waste.
In addition, since the urine itself delays fermentation and decomposition by aerobic fermenting bacteria, urine cannot be easily used as a raw material for compost, and urine treatment becomes extremely difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and an object of the present invention is to separate feces and urine and smoothly compost solid organic waste such as feces and garbage. On the other hand, liquid organic waste such as urine is separately converted to liquid fertilizer to process urine as liquid fertilizer and to effectively use liquid fertilizer when solid organic waste has insufficient water content. It is assumed that.

[0010]

Means for Solving the Problems To achieve the above object, a solution taken by the invention according to claim 1 is to compost solid organic waste such as feces and garbage by a composting treatment facility. Liquid composting of liquid organic waste such as urine and liquid fertilization by liquid fertilization treatment equipment as a method of composting and liquid fertilization of organic waste. In the above composting treatment equipment, solid organic waste Receiving step, a fermentation step of fermenting the solid organic waste received in the receiving step, and an aging step of aging the solid organic waste after completion of the fermentation step. Composting of organic waste. On the other hand, in the liquid fertilization treatment equipment, a receiving step of receiving the liquid organic waste, a heat fermentation step of heating and fermenting the liquid organic waste received in the receiving step, An aeration step in which liquid organic waste is aerated while solid-liquid separation into a solid and a liquid component mixed in the waste, and after the aeration step, the liquid organic waste is stored. A liquid organic waste is subjected to a liquid fertilization treatment through a storage step and a liquid storage step. Then, the liquid fertilizer of the liquid organic waste liquidified in the liquid fertilization treatment facility is supplied as adjusted water for moisture adjustment in the process of composting the solid organic waste in the composting treatment facility. I have to.

According to the first aspect of the present invention, when composting solid organic waste, solid organic waste excluding liquid organic waste such as urine, that is, feces and By using garbage as raw material for compost,
The water content of solid organic waste (feces, garbage, etc.) is reduced, and the temperature in the fermentation process can be increased to promote fermentation and decomposition by aerobic fermentative bacteria. Is suppressed in a short period of time.

On the other hand, liquid organic waste such as urine is deodorized in a short period of time by promoting fermentation and decomposition by aerobic fermentation bacteria by heat fermentation, and then is aerated while solid-liquid separation, and then stored to be liquid fertilizer. Be transformed into

In other words, by separating organic waste into solid and liquid and treating them separately, fermentation and decomposition by aerobic fermenting bacteria during liquid fertilization and composting are each independently promoted, and malodor is reduced in a short period of time. It disappears and liquid manure and compost can be obtained effectively.

In addition, when the solid organic waste after the fermentation step has a shortage of water between the fermentation step and the ripening step of the solid organic waste, the subsequent ripening is performed. The liquid fertilizer of the odorless liquid organic waste that has been liquid fertilized without newly preparing water for water adjustment in preparation for the process is effectively used.

[0015] The solution means taken by the invention of claim 2 is as follows.
In addition to the requirements of the invention according to claim 1, between the receiving step and the fermentation step in the composting treatment facility, the absorbent organic material such as rice hulls is used as an adjusting material for adjusting moisture to solid organic waste. Intervene in the supply of adjusting material. In the adjusting material supply step, the hygroscopic powder is supplied to the solid organic waste by pneumatic transportation.

According to the second aspect of the present invention, when the solid organic waste has a large water content during the receiving step in the composting treatment facility, the hygroscopic powder is supplied in preparation for the fermentation step. Thus, the water content can be adjusted to an optimum water content, the temperature can be smoothly increased in the fermentation step, and the fermentation decomposition by the aerobic fermentation bacteria is further promoted. In addition, the supply of the hygroscopic powder such as the rice husk causes the solid organic waste to be dressed and the odor to be sealed off. Furthermore, since moisture-absorbing powder such as rice hulls is transported by air, powders (such as rice hulls) that are easily scattered during transportation are transported efficiently, and the working environment in the vicinity is improved. Moreover, when the rice hulls and the like are reduced to the soil together with the compost, they become humus, the physical properties of the soil are improved, and the nutrient holding capacity of the soil is enhanced.

Thus, each of the air transport pipes 77a, 83, 83,
The solid organic waste before fermentation is dressed by the crushed rice hulls supplied through the paddle 85 to seal off the odor, thereby effectively suppressing the generation of offensive odor. Furthermore, by transporting the rice husks by air, the rice husks can be transported efficiently without being scattered during transportation, and the working environment in the vicinity can be improved. Moreover, when the crushed rice hulls are reduced to soil together with compost, they become humus, the physical properties of the soil are improved, and the nutrient holding capacity of the soil can be enhanced.

Next, a method for composting solid organic waste in the first step of the composting facility 11 will be described.

First, as a garbage receiving step, as shown in FIG. 1, the garbage transporting cargo truck 3 gets into the first receiving place 11a, and the operator sequentially places the containers 2 on the loading platform 3a in the first pits 12a. The garbage is put into the garbage receiving hopper 13 inside the garbage, and the garbage is dropped on the apron conveyor 14 and replaced.

Next, as a raw garbage adjusting / supplying step, when the amount of water in the raw garbage received in the raw garbage receiving step is too large, the husk crushed To make the water content of the garbage appropriate.

Thereafter, as a garbage transporting step, the garbage is transported by the apron conveyor 14 and then transferred to the garbage transporting conveyor 15 at the downstream end in the transport direction. It is transferred to the conveyor 16.

Thereafter, as a first unsuitable object sorting step, an operator in the monitoring room 17 manually sorts out unsuitable objects such as plastic and glass mixed in the garbage on the horizontal conveyor 16, and selects the unsuitable items. The waste is dumped into the waste box 19 via the chute 18, and the garbage from which the unsuitable material has been removed is transported downstream of the horizontal transport conveyor 16 in the transport direction.

In the cow dung receiving step, the cow dung transport dump truck 4 is driven into the second receiving place 11b,

Then, the cow dung transporting step is continued, and the cow dung is transported onto the horizontal transport conveyor 16 by the cow dung transporting screw conveyor 27 and replaced. In this case, the cow dung transporting screw conveyor 27 is configured to agitate the cow dung and the chaff milled powder during the transportation.

Thereafter, as a solid organic waste transporting step, cow dung is transported together with garbage on the horizontal transporting conveyor 16. In this solid organic waste transporting step, as a solid organic waste adjusting material supply step, rice husk crushed powder is supplied to solid organic waste of cow dung and garbage. I have.

More specifically, the weight of solid organic waste (cow droppings and garbage) is measured on the horizontal conveyor 16 by the weight meter 31. Then, in the fermentation bacterium supply device 33, a predetermined ratio of rice bran to aerobic fermentation bacteria, for example, a mixture of aerobic fermentation bacteria obtained by mixing rice bran at a ratio of about 30 kg with respect to 200 g of aerobic fermentation bacteria, The mixture obtained by mixing the rice husk crushed powder of the second moisture conditioner 34 with 10
00 kg of solid organic waste is supplied through a transport pipe 35. Thereby, even if the water content of the solid organic waste is large, the water content of the solid organic waste can be adjusted to the optimum water content for the subsequent fermentation by supplying the ground rice hulls. As a result, the temperature in the internal space of the rotating drum 36 can be smoothly increased, and the fermentation decomposition by the aerobic fermentation bacteria can be further promoted.

Then, as a fermentation process for solid organic waste, solid organic waste is put into the inlet 36a of the fermentation rotary drum 36 from the horizontal conveyor 16 and the inside of the fermentation rotary drum 36 is turned on. Heating is performed for about 3 hours to about 75 ° C. while stirring and mixing in the space to promote fermentation degradation by aerobic fermenting bacteria.
In this case, the temperature of the internal space of the fermentation rotating drum 36 is maintained only by the heat generated by fermentation decomposition by the aerobic fermentation bacteria.

Thereafter, as a primary ripening step, solid organic waste, the fermentation decomposition of which has been promoted, is dropped from the internal space of the fermentation rotating drum 36 onto the conveyor 37 through the discharge port 36b, and through this conveyor 37. The solid organic waste is sequentially packed in an empty aging container 38. Then, the aging container 38 filled with the solid organic waste is carried to the primary aging chamber 40 by the forklift 39, and the fermentation decomposition of the solid organic waste by the aerobic fermentation bacteria is continued.
In the primary maturation chamber 40, in a state where air is supplied, 60-70 ° due to heat generated by fermentation decomposition by aerobic fermentation bacteria.
The aerobic fermentation is continued for about 4 weeks while maintaining the high temperature of C.

Next, a liquid fertilization treatment method for liquid organic waste by the liquid fertilization treatment equipment 41 will be described.

First, as shown in FIG. 1, as a receiving step, the human waste collection vehicle 5 is moved into the human urine receiving place 41a. Then, the manhole 42d of the liquid heating fermenter 42 is removed, the input port 42e is opened, and the hose 5 is removed from the tank 5a.
b is led out and the tip is inserted into the storage part 42c of the liquid heating fermenter 42, and the cow urine in the tank 5a is transferred to the storage part 42c. When the transfer of cow urine is completed, an aerobic fermentative bacterium is introduced by a predetermined amount from the inlet 42e by an operator or the like.

Next, as a high temperature fermentation step, burner 42
The heating unit 42b is heated by a, and the storage unit 42c is evenly heated from below to heat the cow urine to about 50 to 60 ° C., thereby promoting the fermentative decomposition of the cow urine by the aerobic fermentative bacteria and deodorizing the odor. I do.

Thereafter, as an aeration step, deodorized cow urine is pumped into the first chamber 43a through an opening 43e of the aeration tank 43 via a pipe 44. And this first chamber 43a
Is flowed through the opening 43g to the second chamber 43b, and the relatively mixed solid-liquid separation wire mesh 43k in the cow urine with respect to the facing space 43j of the second chamber 43b.

Solid matter such as relatively small cow dung mixed in the cow urine is blocked and sent to the confronting space 43j of the third chamber 43c by a fine solid-liquid separation wire netting 43m. Then, the blower 48c is operated to supply air through the main air hose 48b and the branch air hoses 48c, and the air is used to agitate the cow urine with the air in the aeration tank 43 to uniformly aerate the cow urine. Activate degradation fermentation by fermenting bacteria.

Thereafter, as a storage step, the third chamber 43c
Cow urine aerated from the confronting space 43j of the submersible pump 4
5, the urine is sent out to a storage tank 47 via a pipe 46, and the cow urine is stored in this storage tank 47 for several days to form a liquid fertilizer.

Here, a method of composting solid organic waste in the latter stage of the composting facility 11 following the earlier stage will be described.

In the first aging step, the solid organic waste that has been subjected to the aerobic fermentation for about 4 weeks in the first aging chamber 40 of the composting treatment equipment 11 is subjected to the second aging step.

In this secondary aging step, the primary aging room 40
Is transported to the secondary maturation chamber 51 by a shovel loader.

It is put into the mouth 54a. Thereafter, the rotating sieve 54 is used to remove unsuitable materials, such as plastic and glass fragments, from the solid organic waste that cannot be completely sorted out by the operator's hand, from the discharge port 54b to the collection container 55c as residues. It is discharged and removed, and the solid organic waste from which unsuitable substances have been removed is sorted by dropping it downward.

Next, as a magnetic sorting step, the solid organic waste from the unsuitable material sorting device 53 is sorted by the magnetic sorting device 55.

More specifically, the solid organic waste dropped below the rotary sieving machine 54 is transferred to the horizontal conveyor 5.
5a, and a magnetic separator 56 is used to flip off magnetic substances such as aluminum and iron from solid organic waste and collect them in a lower magnetic substance collector 58, and remove the magnetic substances. The organic waste is sorted by compost.

Thereafter, as a carry-out step, the compost (solid organic waste) from which the magnetic substances have been removed is transported to the stock yard 57 instead of being mounted on the transport conveyor 55b.
It is transported to the automatic packaging device 59 by the shovel loader 60. Thereafter, the compost is individually packaged by a predetermined amount (for example, 20 kg) by the automatic packaging device 59, transported to a carry-out location 61 by a forklift or the like, stacked on the mounting table 62, and prepared for carry-out (shipment).

Thus, in this embodiment, cow manure and cow manure are separated and collected at the time of collecting cow manure, and solid organic waste excluding liquid organic waste such as cow urine, that is, cow manure, By using garbage and raw compost as raw materials for compost, the amount of water in solid organic waste (cow droppings and garbage, etc.) is reduced, and the temperature in the internal space of the rotating drum 36 can be increased to aerobic. The fermentation decomposition by the fermenting bacteria can be promoted, and the generation of offensive odor can be suppressed in a short period of time.

On the other hand, the cow urine collected at the time of collecting cow manure is burned in the burner 42 in the liquid heating fermenter 42 in the high temperature fermentation step.
a, which is quickly heated to promote the fermentation decomposition by the aerobic fermentation bacteria, thereby being deodorized in a short period of time. Thereafter, in the aeration step, solid-liquid separation is performed in the aeration tank 43, followed by aeration in the storage tank 47 in the storage step. It can be stored and liquid fertilized.

That is, solid organic waste (cow manure and garbage) separated from solid and liquid and liquid organic waste (cow urine)
