Abstract

<P>PROBLEM TO BE SOLVED: To resolve the problem that when compost and stockbreeding animal excreta are conventionally treated to obtain fertilizer or fuel, smell of the compost and the excreta cannot be removed even by drying and exerts adverse influence on living environment of residents living in the vicinity. <P>SOLUTION: After a deodorant solution is poured into the compost and the excreta or the like of the stockbreeding animal, the compost and the excreta are agitated together with the deodorant solution and then the agitated liquid is subjected to solid-liquid separation to separate solid content from liquid. The solid content is blended with wood pieces and wood chips and obtained mixture is pulverized and dried. Thereby the mixture can be preserved in a smell-free state and further no malodor is produced when burned. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a processing apparatus and a processing method for compost and livestock animal manure that generate malodors, and more particularly to a processing apparatus and method for removing compost and livestock animal manure and the like, pelletizing them, and using them as fuel.

  Conventionally, for example, Patent Document 1 discloses a method for drying livestock excrement, pelletizing it, and using it as fertilizer or fuel. In addition, after fermenting and reducing the volume of organic waste, the fermented product is compressed and solidified, composted into pellets molded into a standard shape, and a method for controlling the moisture content is a method for controlling the moisture content as patented 2.

Japanese translation of PCT publication No. 2002-524093 JP-A-11-116369

  Patent Document 1 discloses a technique for expanding the surface area of stool and drying it so as not to have a bad odor with the conventional processing apparatus and processing method such as compost and livestock excrement as described above. Patent Document 2 discloses a method of eliminating malodor by controlling the moisture content. In both cases, it is necessary to reduce the moisture content, and there is a disadvantage that it is costly and troublesome, such as drying or controlling the moisture content.

  The present invention is intended to solve the problems of such a conventional configuration, and since manure and compost itself have malodorous components, the malodor is first removed and pelletized. It is intended for use as a fuel.

  Claim 1 of the present invention is a means for injecting deodorant liquid into manure and manure of livestock animals, a means of stirring manure and animal animal manure in which the deodorant liquid has been injected, and the agitated Means for separating the solids and liquid from deodorant liquid and compost and livestock animal manure, etc., means for mixing the solids with wood chips, wood chips, etc., to produce a mixture, and Means for subdividing the mixture to produce pellets, and a processing device for compost and livestock excreta etc. provided with a compost.

  A sixth aspect of the present invention is dependent on the fourth to fifth aspects of the present invention, and provides a method for treating manure, etc. of compost and livestock animals comprising a step of using the pellets as fuel.

  Claim 7 of the present invention is dependent on Claims 1 and 4, wherein the deodorizing liquid is an alkali-resistant photosynthetic bacterium (Rhodopseudomonas), an alkali-resistant orchid-colored bacterium (Synechococcus), more specifically, an alkali-resistant Rhodopseudomos A strain with bacteria chlorophyll a, neurosporene, lycopene, alkali-resistant bacterial chlorophyll a, photosynthetic bacteria with neurosporene B strain, alkali-resistant chlorophyll a, and orchid with β-carotene The present invention provides an apparatus and method for treating manure, etc. of compost and livestock animals containing a liquid that is a group of microorganisms containing at least one selected from a strain C of bacteria (Synechococcus).

  As described above, in the compost and livestock animal excrement processing apparatus and method of the present invention, after the deodorizing liquid is first injected into the compost and livestock animal excrement, no malodor is produced in the compost and livestock animal excrement, It is also convenient from the environmental point of view when the fuel manufactured using the compost and manure of livestock animals is manufactured.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 shows a processing apparatus for excrement of livestock including chickens according to the present invention, and FIG. 2 shows a processing apparatus for compost.
In FIG. 1, water is added to the deodorant liquid from the deodorant liquid storage tank 1 containing the deodorant liquid, or cleaning water 2 which is a stock solution of the deodorant liquid is sprinkled into the breeding house 3 and at the same time the livestock feces / urine 4 Also put on. The deodorant liquid is put into the agitation mixer 5 from the cleaning water 2 and the deodorant liquid storage tank 1 which are stored in the breeding house 3 and the feces / urine 4 and mixed. Thereafter, the solid-liquid separator 6 separates the liquid into the separated liquid 7 and the separated solid material 8. The separated liquid 7 is put in the settling tank 9 and the precipitated solid 10 is mixed with the separated solid 8. A part of the supernatant liquid 11 other than the precipitated solid matter 10 in the settling tank 9 is guided to the circulation purification treatment tank 12 to form a liquid fertilizer 13 and field spraying 14 is performed as necessary. Moreover, since the liquid which is not used as the liquid fertilizer 13 of the supernatant liquid 11 can be used as the deodorizing liquid 15, it is led to the deodorizing liquid storage tank 1.

  Here, the separated solid 8 and the precipitated solid 10 precipitated in the settling tank 9 are mixed by a wood chip / wood chip mixer 16 for mixing with wood chips / wood chips. It is put into a pelletizer 17 and subdivided and dried with a dryer 18 to produce an odorless pellet fuel product 19.

  In the above example, the stool and urine 5 are described together. However, the scent and urine may be divided into stool and urine, respectively, and the stool and urine may be put into the stirring mixer 6 respectively.

  2 shows compost processing, in which 30 is used as compost instead of feces and urine 5 in FIG. 1, the deodorizing liquid from the compost 30 and the deodorizing liquid storage tank 1 is added to the stirring mixer 6 and stirred. The operation of is the same as in FIG.

  A tour of chicken manure treatment method was conducted as an example of a compost and manure urine treatment apparatus for livestock animals in Kagoshima Prefecture Y Poultry Farm.

  The place where the chicken manure treatment is carried out is in the shed of the Y poultry farm, using the chicken manure from the Y poultry farm, putting the same amount of water as the chicken manure into the water tank, and using a stirring propeller with blades at the tip of the electric drill. When stirring for 3 minutes to 5 minutes, chicken dung dissolves in water and becomes a muddy liquid, which generates bubbles but does not eliminate malodor. Inject the same amount of deodorizing liquid as chicken dung into the stirring solution. When stirring for 5 minutes to 5 minutes, a large amount of small bubbles were generated, so when the smell of the water tank was sniffed for 5 to 10 minutes until the bubbles repelled, the bad odor disappeared.

  In order to separate the mixed chicken and feces mixture, which has been deodorized by stirring, into solid and liquid, it is a rotary solid-liquid separator using a stainless steel mesh No. 120 mesh. In order to confirm that it was dried, the solid matter with a water content of 90% or more was put in a frying pan and heated on a gas stove. It did not stink.

  One of the participants was instructed to put a solid material with a water content of 90% or more separated only by water and chicken manure into a frying pan and heat it on a gas stove. He escaped far from the tour and recognized the effect of the deodorant solution, which did not clear the odor for a while.

  The separated solids were continuously charged into the rotary open dryer, but the chicken manure could be dried without generating bad odor. I picked up the warm solids coming out of the dryer and confirmed the smell, but all the visitors confirmed that they were deodorized.

  Dried chicken manure turned into white ash as soon as it burned, and no foul odors were generated, so we considered a method to produce deodorized chicken manure solids and fuel made from wooden chips. Therefore, we decided to use a commercially available wood pellet manufacturing method.

  The water content was adjusted with chicken manure and wood chips, and the molded product made into pellets could be used as a normal fuel, even if it burned, fired quickly and sustained, and the fire extinguished immediately with chicken manure alone.

  At the Mie composting plant, take out a part of compost mixed with compost and wood chips, put a deodorizing solution about half of the amount of compost and wood chips into a 90 liter garbage bucket, stir with rubber gloves, the bad odor disappears, and the sky No bad odor occurred even after sun drying.

  Horse dung and cow dung are also poured into the aquarium with the same amount of water as the dung, and when stirring with a bladed stirring propeller at the tip of an electric drill for 3 to 5 minutes, the dung melts into the water and becomes a muddy liquid. Injecting the same amount of deodorizing liquid as feces into the stirring liquid and stirring for 3 to 5 minutes will produce a large amount of small bubbles, so until the foam pops, The odor disappeared when the tank was smelled for 5 to 10 minutes.

  In order to separate the dung mixture liquid into solid and liquid, which was deodorized by stirring horse dung and cow dung, it was separated into solid and liquid with a rotary solid-liquid separator using stainless steel mesh No. 120. It took 4 to 5 days to dry the solids in the sun, and the dried dung solids did not smell.

  In the case of horse dung and cow dung, too, the durability to fuel is short, so it can be used as fuel by mixing with wood chips and pelletizing.

  The experiment will be conducted at the Miyazaki Farm, and the feces of the horse feces can be deodorized in a short period of time, and the solids that have been separated into solid and liquid are dried in the sun. Visitors of the ranch were impressed that the butterflies flew and no flies flew because they did not smell when they approached, and that the separated liquid did not feel any bad odor.

  It is a report of the measurement result which asked the Kagoshima Environmental Technology Association for the odor test in Kagoshima Prefecture I pig farm on September 21, 2005.

Manure processing device (6th tank)

  The odor index 26 (odor concentration 430) in the manure processing apparatus (first tank) is considered to be “strong odor” as described above, but the odor index 4 (odor concentration 2) in the manure processing apparatus (sixth tank). It was extremely low. Compared to the wastewater standard (this time adopting the odor index 28 “odor index 12 + 16”, which is the strictest standard in Kagoshima City), the odor index 4 and the odor index 4 are much lower than the standard value. It became.

  From around March 2006, the treated water was finally understood by the deodorant liquid and Mr. I, and it was used for cleaning water in the breeding house. What was the smell in the breeding house that was the pig hut odor 430? It is a weak smell that can be seen, and since it does not smell even if you smell the urine discharged by cleaning and the solid stool that is separated into solid and liquid, it does not smell, so everyone who comes to visit is a pig farm, It is said that it is strange that there is no smell.
