Description

Circulating pig manure treatment method and apparatus including flotation separation {Treatment Method and Apparatus of Swine Wastewater}

The present invention relates to a method and apparatus for treating circulating pig manure, including floating separation, and more particularly, to reduce the odor generated from pigs and further to selectively carry out liquid fertilizer production and discharge of treated water or only liquid fertilizer production. The present invention relates to a method and apparatus for treating circulating pig manure, including floating separation capable of economically and stably treating pig manure.

As a general method for treating manure, there is a situation in which the manure generated from each pig house is collected and processed together in a separate treatment plant or separately installed by installing a treatment plant in each pig house. In addition, these treatment plants produce manure by treating pig manure or remove pollutants to satisfy discharged water quality and discharge them to rivers.

The pig house is provided with a space part where pigs can live, and the manure excreted by the pigs is transferred to the manure storage tank installed below through an outlet provided on the floor. If the manure in the manure storage tank is not discharged frequently, bad smells such as methane gas, hydrogen sulfide, and mercaptan occur, and even pigs die from disease.

In order to solve the problem of odor and maintain clean pigs, the manure of the manure storage tank is frequently discharged, but this requires a lot of equipment installation and labor costs.

In addition to the odor problem, there is a problem in that the treatment cost is excessive when the discharged manure. In other words, in order to discharge the discharged manure to a river, etc., the discharge water quality standards must be satisfied. However, since the manure is contained in a very high concentration of organic matter, a large number of unit treatment processes must be installed to sufficiently remove these organic matters. Expensive to manure treatment. Of course, manure is properly processed and used as liquid fertilizer, but demand is not always constant, so there is a limitation in establishing a treatment system for liquid fertilizer only.

Circulating pig manure treatment apparatus including the flotation separation of the present invention, as shown in Figure 2, the sedimentation basin 100, sediment collection tank 110, flotation separation tank 120, one or more sedimentation tank (250, 260) , 280), solids collection tank 130, first and second treatment tanks 140, 270, dehydration tank 150, one or more aeration tanks (200, 210, 230, 240), anoxic tank 220, activated carbon It may include a treatment tank 290, ozone oxidation tank 300, filtration tank 310 and the broiler chamber (400).

Here, the first aeration tank 200 and the second aeration tank 210 may be operated as one aeration tank, and the third aeration tank 230 and the fourth aeration tank 240 may also be operated as one aeration tank. In addition, it is apparent that the activated carbon treatment tank 290, the ozone oxidation tank 300, and the filtration tank 310 may be omitted as necessary.

In the pig manure processing method according to the present invention comprising the above-described respective unit devices, after treating the pig manure discharged from the manure storage tank (not shown) of the pig company, part of the treated water again the manure storage tank (not shown) By continuously circulating the furnace, it is possible to suppress the occurrence of odor from the pig house, and utilize a part of the treated water as the liquid ratio.

In addition, the liquid separated from the sediment or scum layer discharged from the pig manure process is removed from the organic matter through a biological process and recycled to the pig manure storage tank, or, if necessary, further discharged into the river after the second treatment process. Let's do it.

First, referring to FIGS. 1 and 3, a treatment step in which a part of pig manure treated water is circulated to a manure storage tank and a part of the pig manure is discharged into a river or the like will be described.

Feed the manure of the manure storage tank (not shown) in which the pig manure is collected to the settlement 100. The manure storage tank is supplied with not only manure but also treated water from which organic matter has been removed to a predetermined range, and in the process, it may include heavy foreign substances such as sand (concrete pieces, pieces of steel or stainless steel facilities). After removed from the sediment collection tank 110, the solids collection tank 130 in the order or discharged to the outside.

The sedimentation effluent flowing through the settling paper 100 flows into the flotation separation tank 120 so that a material having a large specific gravity is settled to the bottom, and the relatively small gravity materials attached to the bubble can float on the water. Rises near the surface of the water) to form a scum layer. The sediment precipitated to the bottom is transferred to the solids collection tank 130, the scum layer of the flotation tank 120 is sediment collection tank 110 or solids collection tank 130 by a known scum layer removing means such as a scraper (not shown). Are exported.

Here, the scum layer has a very small specific gravity, and not only contaminants naturally floating near the surface of the floating separation tank 120 but also generate fine bubbles in the pipeline for transporting the effluent outflow of the sedimentation basin to forcibly float solids having a relatively high specific gravity. It may also contain pollutants.

Figure 4 is a cross-sectional view of the line mixer installed in the pipe connecting the settlement and the flotation separation tank, Figure 5 (a) is a view seen from the inlet side of the line mixer, (b) is a view seen from the outlet side.

As shown in Figures 4 to 5, a line mixer for mixing and stirring the sediment effluent water and pressurized air to attach to the surface of the various contaminant particles in the conduit for transporting the sediment effluent water to the flotation separation tank 120 to float more easily. It is preferable that 1000 is further provided. Specifically, one side of the line mixer 1000 is provided with an inlet 1110 through which the sedimentation effluent is introduced, and the other side of the line mixer 1000 is provided with an elongated cylindrical body having an outlet 1120 for discharging a mixture of air and the clarification effluent. 1100, an air inlet 1200 is provided at a predetermined position outside the body 1110 to supply pressurized air that forms an acute angle with a direction in which the effluent water flows in.

In addition, a predetermined position of the body portion 1100, more specifically, the air inlet 1200, the mixture is mixed and agitated the sediment effluent water and the air, and to rotate the micron particles and air contained in the effluent to help the injury more easily Wings 1300 are provided. Furthermore, at least one round bar 1400 coupled to the inner wall of the body 1100 and the central support shaft 1410 is provided at the rear of the rotary blade 1300 to suppress recombination of the micronized pollutants and air particles. As well as prevents foreign matter, including pig hair, from entering the floating separation tank 120 and the first aeration tank 200,

When the line mixer 1000 having the above configuration is installed in the pipe connecting the settlement 100 and the flotation separation tank 120, the contaminated particles contained in the effluent of the settlement are miniaturized, and further, the surface of the contaminated particles is innumerable fine. Since bubbles are attached, the floating separation tank 120 can be easily floated on the water, thereby reducing the total amount of pollutants supplied to the first aeration tank 200. On the other hand, the flotation tank 120 itself corresponds to a device widely used in the art, so a detailed description thereof will be omitted.

Referring to FIG. 3 again, the floating separation tank effluent from which the scum layer which floats due to the high specific gravity sediment and air bubbles are removed is passed through the first aeration tank 200 and the second aeration tank 210 to remove contaminants. do. Air is continuously or discontinuously injected into the lower portion of the first aeration tank 200 and the second aeration tank 210, and aerobic microorganisms live in the first aeration tank 200 and the second aeration tank 210. The contaminant removal technology and mechanism by the aerobic microorganisms described above correspond to known techniques, and thus, a detailed description thereof will be omitted.

In FIG. 3, two aeration tanks, that is, the first aeration tank 200 and the second aeration tank 210 are illustrated as being disposed. However, this is only an example and may be added or subtracted as needed. Do.

Organic matter is removed while the first aeration tank 200 and the second aeration tank 210 are removed, and the outflow water of the second aeration tank 210 is moved to the first precipitation tank 250. In the first sedimentation tank 250, after the aerobic microorganisms grown while ingesting contaminants are separated from the treated water through the sedimentation process, the sediment is transferred to the solids collection tank 130, and the relatively clean purified water is the first treated water tank. It is collected at 140.

The treated water collected in the first treatment tank 140 through the treatment process as described above is supplied to a manure storage tank (not shown) of pigs and is recycled back to the settling basin 100 together with the manure, a manure storage tank (not shown) Manure is quickly discharged to the outside, and therefore, the odor generated in the conventional manure storage tank can be greatly reduced. Specifically, the treated water supplied to the manure storage tank (not shown) has the effect of diluting the manure to the outside while diminishing the generation of odors, and furthermore, if the manure storage tank is maintained in anoxic conditions, Since the denitrification of nitrogen can be expected, the manure treatment cost can be reduced.

Here, the treated water circulated to the manure storage tank is preferably supplied in a volume of 10 to 30 times the manure generated. If less than 10 times, the amount of supply is lower than the manure generated, and the effect of reducing odor is reduced. On the contrary, if more than 30 times, much energy is required to supply the circulating water, and the sedimentation basin must be overdesigned due to the increase of hydraulic load in the first settling tank. In addition, since there is a problem that it is difficult to expect sufficient denitrification due to lack of time to maintain anoxic conditions, it is preferable to supply the treated water supplied to pig manure storage tank (not shown) in a volume of 10 to 30 times as described above. .

Subsequently, the process of treating the solids collected in the solids collection tank 130 will be described. As described above, the solids collection tank 130 includes the sediment and scum layer discharged from the floating separation tank 120 from the first settling tank 250. The generated precipitates and the precipitates transferred from the second settling tank 260 and the third settling tank 280 to be described later are stored, and these precipitates contain a considerable amount of water together.

In the present invention, in order to separate the liquid component from the precipitate, a solid-liquid separation process is performed using a filter, more preferably, a decanter or a belt press. The liquid component recovered from the precipitate, ie, the dehydration liquid, is transferred to the dehydration liquid storage tank 150 for further processing. Specifically, since the recovered dehydration liquid does not go through a biological treatment process, it contains a large amount of organic matter, and thus it is impossible to discharge it to the water system such as a river as it is.

As described above, the dehydration liquid containing a large amount of organic matter is passed through an anaerobic tank 220 operated under anaerobic conditions, a third aeration tank 230 and a fourth aeration tank 240 operated under aerobic conditions, and by anaerobic microorganisms and aerobic microorganisms. Organics, nitrogen, and phosphorus are removed, and the solids are separated from the second precipitation tank 260 to remove contaminants to a predetermined range. In the purification process for discharge of FIG. 3, two aeration tanks, such as a third aeration tank 230 and a fourth aeration tank 240, are illustrated as being disposed, but this is only an example and may be added or subtracted as necessary. It can be obvious.

If the effluent water quality standard is satisfied through the above treatment process, it can be discharged as it is without additional treatment. If the effluent water quality standard is not satisfied, a separate treatment process should be further performed. For example, after storing the second sedimentation tank effluent in the second treatment water tank 270, fine floating particles are removed using a pressure floater (not shown), and then the ozone oxidation tank 300 and the activated carbon filtration tank 290. Into the third settling tank 280 and the filtration tank 310, a known treatment may be further performed. Here, the discharge amount to the stream, etc. may be determined in consideration of the washing water newly supplied from the outside for washing the manure storage tank, the amount of manure generated and the amount of solids discharged to the outside.

On the other hand, the separated solid may be used as a compost after the composting process such as fermentation and ripening, or may be disposed of landfill after drying at a water content of a predetermined range.

Next, referring to FIGS. 1 and 6, a part of the treated water is discharged to the outside for use as a liquid ratio, and the remaining treated water is circulated to the manure storage tank without being discharged into the river or the like. Explain.

The treatment process is substantially the same as the treatment process described with reference to FIG. 3 except for the treatment of the solids and scum layers gathered in the solids collection tank 130. Therefore, after supplying the manure stored in the manure storage tank of the pigs in the same process to the settling place (100), the sediment effluent is supplied to the flotation tank 120 to transfer the sediment to the solids collection tank 130, while the liquid that does not settle The step of supplying to the first aeration tank 200, after removing the organic matter in the first aeration tank 200 and the second aeration tank 210 and settled in the first sedimentation tank 250, the precipitate is a solids collection tank 130, the treated water is first 1 to the treatment tank 140, and the description of the process of circulating the treated water collected in the first treatment tank 140 to the manure storage tank of pigs will be omitted.

In the above treatment process, when the demand for liquid fertilizer is sufficient so that it is not necessary to discharge livestock wastewater generated during the treatment of pig manure, part of the treated water is circulated to the manure storage tank, and the other portion is a treatment process for use as liquid fertilizer.

In general, most livestock farms are inexpensive to operate or have unnecessary processes because they are equipped with a treatment process to treat the discharged manure and discharge it into a stream or to achieve only one purpose of liquid fertilization. Mostly.

In the solids collection tank 130, the sediment and scum layers discharged from the flotation tank 120, the first precipitation tank 250, the second precipitation tank 260, and the third precipitation tank 280 are collected, and these precipitates contain a considerable amount of water. It contains together. As described above, a filtration (solid / liquid separation) process is performed to separate the liquid from the solid, and the dehydration liquid is transferred to the dehydration liquid storage tank 150.

The recovered dehydrated liquid is high in organic matter because it has not undergone a biological treatment process, and therefore an additional purification process is required to circulate the manure reservoir. The dehydration liquid as described above is first supplied to the oxygen-free tank 220, and then the organic matter is oxidized mainly by aerobic microorganisms while passing through the third aeration tank 230 and the fourth aeration tank 240. Subsequently, after the solids are separated from the second settling tank 260, the solids are introduced into the second aeration tank 210 to be joined with the treated water moving in the order of the floating separation tank 120 and the first aeration tank 200.

In this case, when it is not necessary to discharge the treated water, it is also possible to supply the dehydration liquid of the dehydration liquid storage tank 150 to the first aeration tank 200 or the second aeration tank 210, but the oxygen-free tank 220 and the third aeration tank ( 230 and more preferably supplied and circulated in the order of the fourth aeration tank 240.

Specifically, the anaerobic microorganisms in the anaerobic tank 220, the aerobic microorganisms are proliferating in the third aeration tank 230 and the fourth aeration tank 240, and thus must be fed to maintain the normal state of these microorganisms. If these reactors do not operate in a steady state, a considerable time is required to plant new microorganisms and return them to a normal state, and therefore, even when no liquid discharge is required, the anoxic tank 220, the third aeration tank 230, and the This is because it is necessary to operate the aeration tank 240 in a steady state at all times so that the purification process for discharge can be performed at any time.

Meanwhile, some or all of the treated water passing through the first aeration tank 200 and the second aeration tank 210 sequentially may be supplied to the oxygen-free tank 220. Since the manure storage tank is operated as an anaerobic tank, the oxidized nitrogen nitrate is removed by nitrogen gas in the course of passing through the first aeration tank 200 and the second aeration tank 210, but the hydraulic retention time in the manure storage tank is insufficient. In this case, it is difficult to expect sufficient denitrification. However, by utilizing an anoxic tank 220 used as a purification treatment for discharge, sufficient denitrification can be expected, and organic matter in the process of sequentially passing the anoxic tank 220, the third aeration tank 230, and the fourth aeration tank 240. Since this is further removed, it is possible to supply a cleaner treatment water to the pig manure storage tank.

A part of the pig manure treated water is circulated to the manure storage tank, and the remaining part is discharged to a river or the like, and the treated water of the first treated water tank 140 is discharged at a certain amount of liquid ratio.

The specific parts of the present invention have been described in detail above, and for those skilled in the art, these specific descriptions are merely preferred embodiments, and the scope of the present invention is not limited thereto. It is apparent to those skilled in the art that various changes and modifications can be made within the scope and spirit of the art, and such variations and modifications are within the scope of the appended claims.
