Description

Method for pig excreta treatment

The present invention relates to a pig manure treatment method, and more specifically, in the process of adhering the slurry of pig manure discharged from a pig pen, a deodorizing agent is added and heated and stirred to remove the bad smell of pig manure at the beginning of the pig manure treatment process. It relates to a method of processing pig manure that prevents bad odors from occurring during the overall process of treating pig manure by removing it.

A living space for pigs is provided in the pig farm, and the pig manure excreted by the pigs is stored in a manure storage tank installed below through a penetration hole provided in the floor. Pig manure contains odor-emitting substances such as methane gas and hydrogen sulfide mercapdan, which creates a strong odor. If pig manure is not discharged frequently from the manure storage tank, pigs may contract disease and die.

If pig manure discharged from a manure storage tank is discharged without treatment, it causes serious environmental pollution. Therefore, pig manure normally discharged from the manure storage tank must undergo a predetermined treatment process before being discharged. However, pig manure contains a very high concentration of organic matter, and in order to satisfy the discharge water quality standards, the organic matter in the pig manure must be sufficiently removed. In order to sufficiently remove the organic matter contained in the pig manure, multiple unit treatment processes are required. There is a problem that a large cost is incurred because it must be installed.

To solve this problem, in Republic of Korea Patent No. 10-2198471, pig manure discharged from pig farms is separated into solids and manure liquid using a solid-liquid separator, and the separated solids are composted through fermentation and post-ripening, and separated. One manure solution discloses a 'circulating liquid fertilizer manufacturing system for pigs' (hereinafter referred to as 'conventional patent') that removes odorous substances from a fermentation tank and turns them into liquid fertilizer.

However, in the case of conventional patents, there is a limitation in that a large odor is generated during the treatment process before removing odorous substances from the fermenter. In addition, excipients such as sawdust are added in the process of separating pig manure into solids and liquids, but there is also a limitation that the economic burden due to the cost of these excipients still remains.

Republic of Korea Patent No. 10-2198471 Republic of Korea Patent No. 10-0951307

The present invention is to solve the problems of the prior art mentioned above, and the purpose of the present invention is to add a deodorizer and heat and stir in the process of making the slurry of pig manure discharged from the pig pen stick to the pig manure, The aim is to provide a pig manure treatment method that removes the odor of pig manure at the beginning of the treatment process.

In addition, another object of the present invention is to provide a pig manure treatment method that minimizes the amount of excipients input by making slurry stick from pig manure and reusing the separated solids as excipients.

In addition, another object of the present invention is to provide a pig manure treatment method in which a part of the separated manure solution is stored in a washing water storage tank and reused as washing water for pig farms since the separately discharged manure solution contains a deodorant. .

The pig manure treatment method according to an embodiment of the present invention involves adding a deodorant and an excipient to the pig manure discharged from a pig pen, heating and stirring it through a heating stirrer, removing the bad smell of the pig manure, and adding a slurry of the pig manure to the excipients. It includes a heating and stirring step to cause adhesion, and a solid-liquid separation step in which the solids produced by the slurry sticking to the excipient and the manure liquid from which the slurry has been removed from the pig manure are separated and discharged through a solid-liquid separator.

It may further include a step of supplying washing water to be used as washing water by supplying it to the pig pen.

In addition, the pig manure treatment method according to this embodiment may further include a solids treatment step of supplying the solids separated and discharged from the solid-liquid separator to a heating agitator to be reused as an excipient in the heating agitator, or producing compost through the solids. there is.

Additionally, in the solids treatment step, the solids used for compost production in the heating stirrer may be solids that have been reused as an excipient at least once to further adhere the slurry.

In addition, the solid material processing step includes measuring the weight of the solids supplied from the solid-liquid separator in a heating stirrer, determining whether to reuse the solids as an excipient based on the measured weight, and depending on the result of the decision to reuse the solids as an excipient. It may include the step of reusing the supplied solid material as an excipient, or drying and fermenting the supplied solid material to produce compost.

In addition, in the step of determining whether to reuse as an excipient, if the weight of the measured solid is less than the standard weight, reuse as an excipient is decided. If the weight of the measured solid is more than the standard weight, compost production is decided. The standard weight is the excipient. By reusing it, it can be set lightly as the number of consecutive decisions increases.

In addition, the deodorant added in the heating and stirring step may be a deodorant manufactured by adding functional silicate clay minerals to crude wood vinegar from which the tar component has not been removed by producing softwood through a dry carbonization method.

According to the present invention, in the process of adhering the slurry of pig manure discharged from the pig pen, a deodorizing agent is added and heated and stirred to remove the bad smell of pig manure at the beginning of the pig manure treatment process, thereby eliminating the overall process of treating pig manure. Bad odor may not occur.

In addition, the present invention allows slurry to stick from pig manure and reuses the separated solids as excipients, thereby minimizing the amount of excipients input, thereby reducing the cost burden on excipients, and the amount of slurry stuck during the reuse process increases. do.

In addition, in the present invention, since the separately discharged manure solution contains a deodorant, a part of the separately discharged manure solution can be stored in a washing water storage tank and reused as washing water for pig farms, thereby saving the cost of washing water. Additionally, the waste water used as washing water can be saved. Since the liquid is sterilized through a heating process, using the washing water can be beneficial to the health of the pigs.

Hereinafter, the method of treating pig manure according to the present invention will be examined in more detail with reference to the attached drawings.

Figure 1 is a block diagram schematically showing a pig manure treatment system to which the pig manure treatment method according to an embodiment of the present invention is applied.

The present invention is to remove the odor of pig manure discharged from a pig pen and separate solid-liquid to produce liquid manure and compost. The pig manure treatment method according to this embodiment includes adding a deodorant and heating and stirring at the initial stage of the pig manure treatment process. By ensuring that the odor of pig manure is removed at the beginning of the pig manure treatment process, bad odors are prevented from occurring during the overall process of treating pig manure.

Looking at the pig manure treatment system to which this pig manure treatment method is applied with reference to Figure 1, the pig manure treatment system includes a pig pen 10 into which washing water is input and pig manure containing the injected washing water is discharged, and the pig manure discharged A heating stirrer (30) that removes bad odors and causes the slurry of pig manure to stick to the excipients, a solid-liquid separator (50) that separates and discharges the excipients and manure liquid to which the slurry adheres, and the manure separated and discharged from the solid-liquid separator (50). It may be configured to include a liquid manure storage tank 70 that stores part of the liquid and liquefies it, and a washing water storage tank 90 that stores the remaining part of the manure liquid separated and discharged from the solid-liquid separator 50 and supplies it to the pig pen 10. .

The pig pen 10 is a space where pigs are raised, and a manure storage tank is formed at the bottom of the pig's living space, and a through hole communicating with the manure storage tank is formed at the bottom of the pig's living space. Washing water is sprayed into the pigs' living space to improve hygiene and reduce odor inside the pig pen, and the pig's manure is stored in a manure storage tank along with the sprayed washing water. Here, the pig manure stored in the manure storage tank contains a large amount of washing water.

Pig manure stored in the manure storage tank is discharged to the outside of the pig pen (10), and for this purpose, the manure storage tank is provided with a discharge means such as a pump or transfer screw, or the bottom surface is inclined downward toward the discharge direction to guide the manure discharge flow path. It can be.

Pig manure discharged from the pig pen (10) is supplied to the heating stirrer (30). The heating stirrer 30 heats and stirs the pig manure with a deodorant and excipients added in order to remove the bad odor of the pig manure supplied from the pig pen 10 and to cause the slurry contained in the pig manure to stick and be removed.

At this time, the deodorant added to remove the odor of pig manure in the heating stirrer (30) can be manufactured by adding functional silicate clay minerals to the crude wood vinegar from which the tar component has not been removed by producing softwood through a dry carbonization method. there is.

Specifically, functional silicate clay minerals added to crude wood vinegar can be zeolite, activated clay, etc.; the larger the specific surface area, the higher the adsorption capacity of malodorous components, so it is preferable to use a relatively high specific surface area. This broad zeolite can be used.

In addition, the higher the fineness of the zeolite, the larger the specific surface area, so zeolite particles that have passed through a sieve with a particle size of 100 mesh or more after pulverization can be used. At this time, since grinding time and cost are required to increase the fineness of zeolite, the particle size of the sieve may be 300 mesh or less to prevent excessive grinding time and cost.

In this way, the zeolite added to the deodorant can further improve the odor removal effect of the deodorant by adsorbing and removing odor-causing substances from organic waste that remain after being removed by crude wood vinegar. Additionally, zeolite can remove the unique odor of crude wood vinegar contained in deodorants. And since zeolite increases the adsorption and retention capacity of inorganic nutrients in the soil, improved quality compost can be produced from organic waste.

The deodorant can be prepared by stirring 90 to 99% by weight of crude wood vinegar and 1 to 10% by weight of zeolite at room temperature at a speed of 200 to 250 RPM for 2 to 3 hours. At this time, if the amount of zeolite added is further increased, the adsorption capacity for malodorous components can be expected to increase, but considering economic efficiency, it is preferable to limit it to 10% by weight or less.

And the deodorant introduced into the heating stirrer 30 may be added at 1% by weight based on pig manure.

The heating stirrer 30 assists the odor removal reaction of the deodorant through heating and stirring. For example, the heating stirrer 30 can add a deodorant and a booster to the pig manure supplied from the pig pen 10, heat it to 150°C, and stir it at a speed of 250 rpm for 3 hours. In this way, the heating stirrer 30 heats the pig manure to a high temperature of about 150°C, thereby enabling sterilization of the pig manure during stirring. In addition, when heating and stirring in the heating stirrer (30), raw water is added

Such high-temperature heating evaporates water during stirring and prevents the pig manure from being greatly diluted by the supplied raw water.

The excipient added to the heating stirrer 30 may be organic waste such as sawdust or rice husk, and the excipient added to pig manure may cause the slurry of pig manure to stick during heating and stirring to produce solid matter. Pig manure that adheres to the excipients and has the slurry removed becomes a manure liquid. And the pig manure and excipients supplied to the heating stirrer 30 become solids floating in the manure liquid when the heating and stirring is completed.

In this way, the manure liquid in which solids are suspended is supplied to the solid-liquid separator (50). The solid-liquid separator 50 separates and discharges the supplied solids and manure liquid. Specifically, the solid-liquid separator 50 may be used to pass the manure liquid with solids filtered through a fine mesh, generate vibration in the fine mesh, and discharge the solids filtered through the fine mesh to one side, but is not limited to this. , one or more solid-liquid separation methods may be selected and applied among various conventional solid-liquid separation methods that separate solids and liquids and discharge them.

The solids separated and discharged from the solid-liquid separator 50 may be provided back to the heating stirrer 30. Here, the solid material provided back to the heating stirrer 30 can be composted in the heating stirrer 30 or reused as an excipient, and a more detailed description of this will be described later with reference to FIG. 3.

Some of the manure liquid separated and discharged from the solid-liquid separator 50 may be supplied to and stored in the liquid manure storage tank 70, and the remaining portion may be supplied to the washing water storage tank 90 and stored. Specifically, 70% of the sewage liquid separated and discharged from the solid-liquid separator 50 may be supplied to the liquid manure storage tank 70, and the remaining 30% of the sewage liquid may be supplied to the washing water storage tank 90, but is limited to this. That is not the case.

The manure liquid stored in the liquid fertilizer storage tank 70 can be converted to liquid fertilizer through a predetermined treatment process. Specifically, the liquid manure storage tank 70 may be equipped with an aeration module that supplies oxygen to the stored manure solution to promote composting, and microorganisms may be introduced to promote the composting of the manure solution. In this way, the manure liquid that has undergone the composting process in the liquid fertilizer storage tank 70 can be liquefied and used as liquid fertilizer.

In this way, the pig manure treatment method according to this embodiment can produce liquid manure using the pig manure discharged from the pig pen 10, and the produced liquid manure can be sold to provide profit to pig pen farmers.

The manure liquid stored in the washing water storage tank 90 can be supplied to the pig pen 10 as washing water. At this time, the manure liquid stored in the washing water storage tank 90 has been sterilized by high-temperature heating in the heating stirrer 30, so when supplied to the pig pen 10 and used as washing water, it can be beneficial to the health of pigs in the pig pen. In addition, the deodorant added in the heating stirrer 30 may remain in the manure liquid supplied from the washing water storage tank 90 to the pig pen 10, which has the effect of removing bad odors in the pig pen when the manure liquid is used as washing water. .

As described above, the pig manure discharged from the pig pen 10 is discharged with washing water included. Since the manure liquid used as the washing water is mixed with a deodorant, when the waste liquid stored in the washing water storage tank 90 is used as the washing water. Pig manure discharged from the pig pen 10 may be discharged with some deodorant included. Therefore, when adding a deodorant to pig manure discharged from the pig pen 10 in the heating stirrer 30, a sufficient odor removal effect can be shown even if the amount added is reduced, thereby saving the cost of the deodorant.

Figure 2 is a flow chart schematically showing a pig manure treatment method according to an embodiment of the present invention.

Looking at the pig manure treatment method according to an embodiment of the present invention with reference to FIG. 2, first, a deodorant and an excipient are added to the pig manure discharged from the pig pen 10, heated and stirred through a heating stirrer 30, and the pig manure is It can remove the bad smell of manure and make the slurry of pig manure stick to the excipient (S10).

When heating and stirring is completed in the heating stirrer 30, the manure liquid in which solids are suspended is supplied from the heating stirrer 30 to the solid-liquid separator 50. And the solid-liquid separator 50 separates and discharges the supplied solids and manure liquid (S20).

The solids separated and discharged from the solid-liquid separator 50 are re-supplied to the heating stirrer 30 and undergo a solids treatment process in which they are reused as excipients or composted (S30). A more detailed description of this solids treatment process is shown in FIG. 5. This will be described later with reference to .

Then, part of the manure liquid separated and discharged from the solid-liquid separator 50 is stored in the liquid fertilizer storage tank 70, and the remaining part is stored in the washing water storage tank 90 (S40). At this time, the supply of the solids separated and discharged from the solid-liquid separator 50 to the heating agitator 30 and the supply of the manure liquid separated and discharged from the solid-liquid separator 50 to the liquid manure storage tank 70 or the washing water storage tank 90 are in order. It can be done regardless and can be done simultaneously.

The manure liquid stored in the liquid manure storage tank 70 is converted to liquid fertilizer through a predetermined composting process (S50), and the manure liquid stored in the washing water storage tank 90 can be supplied to the pig pen 10 as washing water (S60). Here, the liquid fertilizer storage tank 70 and the wash water supply process of the wash water storage tank 90 can be performed continuously regardless of the order of the entire pig manure treatment process.

Figure 3 is a diagram illustrating a process in which solids are reused in a pig manure treatment method according to an embodiment of the present invention.

As described above, the solid material provided back to the heating stirrer 30 can be composted in the heating stirrer 30 or reused as an excipient. Hereinafter, the solid material reuse process will be examined in more detail with reference to FIG. 3.

First, the excipients in the initial state are put into the heating stirrer 30 and heated and stirred together with pig manure. The excipient forms a solid by causing the slurry of pig manure to stick during the heating and stirring process. The formed solids are supplied to the solid-liquid separator 50 in a floating state in the manure liquid after the heating and stirring is completed, and can be filtered in the solid-liquid separator 50 and discharged separately from the manure liquid. And the solids separated and discharged from the solid-liquid separator 50 can be supplied back to the heating stirrer 30.

The solids supplied to the heating stirrer 30 can be reused as an excipient again in the heating stirrer 30 or can be composted. At this time, the solid material used for compost production in the heating stirrer 30 may be a solid material that has been reused as an excipient at least once or more to further adhere the slurry.

The solid may be reused as an excipient about 10 times and then composted, but is not limited to this. When composting of the solids supplied from the solid-liquid separator 50 is determined, the heating stirrer 30 can dry the supplied solids for a predetermined time (about 12 hours) to compost the solids. Here, the solid material being composted is reused several times as an excipient, and the amount of slurry stuck during the reuse process increases, so the pig manure treatment method according to this embodiment is capable of producing compost of sufficient concentration.

Figure 4 is a functional block diagram of a heating stirrer according to an embodiment of the present invention.

When solids are supplied to the heating stirrer 30 as described above, the heating stirrer 30 can reuse the supplied solids as excipients or compost them. At this time, whether to reuse the solids supplied to the heating stirrer 30 as an excipient can be determined by considering the state of the solids (amount of attached slurry, etc.). Such a decision may be made by the manager, but in this embodiment, The following heating and stirring can also be performed directly without administrator intervention.

To this end, the heating stirrer 30 according to this embodiment includes a weight measurement module 31 that measures the weight of the solids supplied from the solid-liquid separator 50, as shown in FIG. 4, and a weight measurement module 31 based on the weight of the measured solids. Thus, it may be configured to include a reuse decision unit 33 that determines whether to reuse the solid as an excipient, and a standard weight setting unit 35 that sets a reference weight that serves as a reuse decision standard in the reuse decision unit 33.

The heating stirrer 30 may be provided with a solids container that accommodates solids supplied from the solid-liquid separator 50, and a weight measurement module is provided on the lower side of the solids container to measure the weight of the solids contained in the solids container. .

The weight measurement module 31 provides weight information of the measured solids to the reuse decision unit 33. The reuse decision unit 33 determines reuse as an excipient if the weight of the solids provided is less than the standard weight set in the standard weight setting unit 35, and on the other hand, if the weight of the measured solids is more than the standard weight, it determines compost production. You can.

Here, the weight of the solid is the sum of the weight of the excipient and the adhered slurry, and the set reference weight may be the weight of the initially added excipient plus the expected weight of the slurry that is expected to adhere. For example, if the weight of the excipient initially added is 100 kg and you want to compost after 20 kg of slurry adheres to the excipient, the standard weight can be set to 120 kg.

In this way, the reuse decision unit 33 determines the reuse or composting of solids based on the set reference weight, so the slurry content of the produced compost can be kept constant, so the quality of the produced compost can be consistently maintained.

Meanwhile, the standard weight setting unit 35 may set the standard weight based on the expected weight value input from the manager. Specifically, when the manager inputs the excipient into the heating stirrer 30, the excipient is added to the solids container and then the excipient is added in the initial state (slurry not sticking) through the input unit provided in the heating stirrer 30. You can select and enter the input and enter the expected weight value. At this time, if the input of the expected weight value is omitted, the reference weight setting unit may determine the expected weight value as a predetermined value. The weight of the excipients added to the solid container is measured by the weight measurement module 31, and when the standard weight setting unit 35 inputs through the input unit that the input is the excipient in the initial state, the weight measurement module 31 The weight value (weight value of excipients) measured in is provided, and the weight obtained by adding the expected weight value to the provided weight value can be set as the standard weight.

Preferably, the standard weight setting unit 35 is provided with the decision result of the reuse decision unit 33, and can set the reference weight lighter as the number of consecutive times the reuse decision unit 33 determines to reuse the solid agent increases. there is. For example, if the standard weight setting unit 35 sets the standard weight to 120 kg and decides to reuse the solid agent, the standard weight setting value can be set lighter (for example, to 118 kg) and reset. And, when deciding to reuse the solid material supplied in the next round, the reuse decision unit 33 may decide whether to reuse it based on the reset reference weight (118 kg). If the weight of the supplied solids is measured to be greater than the reset reference weight and the reuse decision unit 33 determines composting of the solids, the reference weight setting unit 35 may initialize the reference weight setting value.

Figure 5 is a flowchart showing the solids treatment process in the pig manure treatment method according to an embodiment of the present invention.

As described above, the solids separated and discharged from the solid-liquid separator 50 are re-supplied to the heating stirrer 30 and undergo a solids treatment process in which they are reused as excipients or composted. Hereinafter, refer to FIG. 5 for this solids treatment process. So let's explain it in more detail.

First, when the solids separated and discharged from the solid-liquid separator 50 are supplied to the heating stirrer 30, the weight of the solids is measured by the weight measurement module 31 (S31). And the reuse decision unit 33 may determine whether the weight of the solids measured at the time when the supply of the solids is completed is more than the set standard weight (S32). Here, the reuse decision unit 33 continuously receives weight information of the measured solids from the weight measurement module 31, and if the weight information of the provided solids does not change for more than a predetermined time, it can be determined that the supply of solids is complete. .

If the measured weight of the solid is less than the set reference weight (S32-N), the reuse decision unit 33 may decide to reuse the supplied solid as an excipient (S33). And when reuse is decided, the standard weight setting unit 35 can reset the set standard weight by making it lighter by a predetermined weight (S35).

On the other hand, if the measured weight of the solid is more than the set reference weight (S32-Y), the reuse decision unit 33 may decide to compost the supplied solid (S36). And when composting is decided, the standard weight setting unit 35 can initialize the standard weight that was set to decrease (S37).
