Description

Pig night soil treating apparatus of environment circulation-type and its method

The present invention relates to a livestock wastewater treatment apparatus and method, and more particularly, to an environment-friendly pig manure treatment apparatus and treatment method applied to pigs.

Conventional livestock waste treatment is a method for collecting and treating livestock wastewater separately. Specific methods include the method of producing liquid fertilizer, which is a natural circulation method, and a method of purifying and discharging them.

In the individual treatment method, for example, in the case of a conventional pig house, the upper part is made of a piglet of a wide shape and the lower part is a narrow shape, and the bottom plate is formed with a through hole at the upper part, so that the manure manure falls down through the through hole.

In such a structure, those who remain in the upper part after discharging urine from pigs have to be scraped down, and it takes a lot of time to collect them in the collection tank and discharge them by chemical treatment. It is so severe that livestock becomes vulnerable to disease and easily get sick.

In the process of continuously ventilating gases such as methane gas, hydrogen sulfide, and methyl melcaptan, which are the source of bad smell, a lot of heating costs are required during the winter season, which may cause civil complaints due to bad smell, and drugs for treating manure are used. There are many problems such as costly and solids and sludge of the pig flour generated when separating the large amount. In particular, the disposal of money is a very big problem.

In the case of the conventional continuous processing apparatus, a high concentration of organic pig manure is taken out and processed for continuous processing to sequentially process low concentrations. In this case, anaerobic and aerobic fermentation are combined to take a lot of load. That is, even when the aerobic microorganism is administered, the microorganism grows poorly and becomes anaerobic due to lack of oxygen, and a trouble occurs in which a large amount of bubbles are generated along with a toxic odor and a treatment period takes 25 to 30 days. In addition, expensive defoamers are added to remove the excess foam, and sawdust and chaff are added as a moisture control agent to compost, resulting in high processing costs.

In addition, a typical example of a liquid manure manufacturing process using manure manure is a chemical process such as a coagulant containing a large amount of heavy metal in the solid-liquid separation process separating the manure and the urine (about 1: 9) contained in the pig manure in this process The sludge produced contains chemicals, making it difficult to use as compost.In the liquid fertilizer manufacturing process without chemicals, there are many restrictions on the use of liquid fertilizers due to bad smell caused by decay due to high concentration of organic matter in pig manure. In the process, decomposing organic substances by simple aerobic digestion generally requires a lot of power costs for oxygen supply in the manufacturing process, excessive bubbles are generated, and are leaked to the outside, resulting in odor and complaints.

The present invention utilizes as a microbial activating tank to utilize the pig powder storage tank installed in the lower pigs as a microbial activation tank, the drug is not used at all to treat the pigs manure and keep the inside of the pig odor free and pleasant and at the same time It is an object of the present invention to provide an eco-friendly and economical pig breeding and wastewater treatment method and apparatus by maintaining a constant temperature inside the pig house by the heat generated during organic decomposition.

Therefore, the present invention has an object of the present invention to provide a livestock company that does not require any heating in winter.

Hereinafter, the other object and structure of this invention are explained in full detail.

In addition, according to the present invention can be eliminated by the configuration of the fermentation tank in the bottom of the pig odor can be eliminated odor generated inside the pig shed and livestock can grow in a pleasant environment can produce more quality meat without stressing the cattle.

1 illustrates an embodiment of the present invention.
2 is a configuration example of the solid-liquid separation device

Hereinafter, the present invention will be further described based on the accompanying drawings.

1 is a view for explaining an apparatus according to the present invention.

As shown, the present invention consists of the bottom plate 2 of the pig 1 having a through hole 3, so that the manure of the pig fall to the bottom 5 below. In the present invention, the pig's lower structure is utilized as a fermenter 10 for activating microorganisms. In other words, if the aerobic microorganisms are put into the fermentation tank 10 and used as a fermentation, the odor of pigs is removed.

The height from the bottom plate 2 to the bottom 5 is preferably 80-90 cm.

If you deepen more than 1 meter, the manure is too much and too deep to meet the fermentation conditions. The deeper the depth, the less oxygen supply, the more difficult and expensive to make aerobic fermentation conditions.

When fermentation is carried out in the fermentation tank 10, a lot of heat is generated, and the generated heat is generated about 30 degrees Celsius or more, so it can be used for heating of pigs, so that no additional heating costs are incurred.

In addition, since the moisture of the pig manure in the fermentation tank 10 in the pig house by the fermentation heat can reduce the amount of waste water. 5 liters of manure per pig per day is generated. According to the configuration of the whole system, about 5 liters of evaporation takes place, so if 1000 heads are allowed to evaporate 5 tons of waste water per day, the amount of evaporation is considerable, greatly reducing the volume. Can be. For reference, about 4 pigs are put in 1 pyeong of pig house, and if it is 250 pyeong, it can raise about 1000 heads.

According to the said structure, a separate fermentation tank is unnecessary.

In the fermentation tank 10, an outlet 6 and a valve 7 are formed to extract the fermented manure and enter the solid-liquid separator 40.

In the solid-liquid separation device as a device for separating the solid and liquid of the pig urine, for example, using a decanter or the like to separate the solids and the remaining liquid is introduced into the bioreactor (50). Another example of the solid-liquid separation device 40 may be a sieve method, and another innovative method is to produce fine bubbles and remove the solids entrained in the manure waste water by floating them around the top of the fine bubbles. It can also be configured to remove even fine suspended solids.

For example, as shown in Figure 2, the rotary shaft 17 with the impeller 8 is installed in the pressure inlet chamber 100 is rotated by the operation of the motor (9). And the rotation shaft 17 is pipe-shaped, The inside is formed in cavity.

A plurality of through holes 111 are formed on the outer circumference of the rotary shaft 17, and air is ejected through the through holes 111. This produces air bubbles in the waste water and the impeller 8 stirs at high speed to break up the generated large air bubbles. This breaks up into fine air bubbles. The fine air bubbles (103) is wrapped in the heavy suspended solids such as dust or foreign matter contained in the urine in the waste water to rise to the top. Thus, the solids in the wastewater are separated from the liquids

In addition, the supplied air is dissolved in the liquid wastewater to increase the concentration of dissolved oxygen to provide an environment for growing aerobic microorganisms.

Bioreactor 50 is composed of a number of devices, the first inlet is an anaerobic tank (51). Here, denitrification is carried out. Swine wastewater has a higher nitrogen concentration than organic matter concentration, so it has to be denitrified by pretreatment. Normally, the ratio of BOD: N: P should be about 100: 5: 1 in wastewater treatment, but the actual pig waste water should be removed by nitrogen through denitrification because the ratio of BOD: N is only 5: 1. Can match

When the denitrification treatment is performed in the oxygen-free tank 51 by a known method, the next is introduced into the aeration tank 53 in which the aeration device 52 is installed.

The aeration device 52 is provided with an oxygen measuring instrument 54 can adjust the aeration conditions so that the microbial fermentation in aerobic conditions is optimal. The defoaming device 55 is installed together with the aeration device 52. The reason for the installation is that in the process of high concentration of organic matter and aeration, a large amount of bubbles are generated due to overproduction of metabolic products of microorganisms, overflowing to the outside of the bioreactor 50, and scattering to the outside is feared. It is necessary to have a device that bursts and converts it into water continuously. Since the defoaming device 55 has various known facilities, a detailed description thereof is unnecessary.

Wastewater having passed through the aeration tank 53 sequentially enters the second anaerobic tank 56 and the second aeration tank 57. The treatment here is the same as that in the anoxic tank 51 and the aeration tank 53 above. This second denitrification by anaerobic microorganisms under anoxic tank conditions, and aerobic microbial fermentation under aeration tank conditions where oxygen is supplied, makes almost perfect wastewater treatment possible.

Then, the treated wastewater enters the microorganism separation device 58 and then enters the final microorganism storage tank 59. In the microorganism storage tank 59 is re-injected into the fermentation tank 10 of pig sand (1). In this way circulation is achieved. In other words, the supernatant from the microorganism storage tank 59 is continuously re-injected into the fermentation tank 10 of the pig company.

The microbial separator 58 does not separate microorganisms separately, but utilizes an excessively large amount of microorganisms contained in the treated wastewater to send a portion of the treated water to the solid-liquid separator 40. As an example of the solid-liquid separator which is particularly used here, it applies to the solid-liquid separator which floats solids by forming a micro air droplet in the processing tank of a solid-liquid separator. In order to assist in the decomposition of organic matter in this treatment tank, wastewater in the microorganism separation device 58 including fermentation microorganisms is introduced and used for organic decomposition by microorganisms.

According to the circulation treatment according to the above configuration, for example, when 10 tons of waste water is generated in pigs, about 1 ton is separated into solids in the solid-liquid separator 40, and the remaining 9 tons is transferred to the bioreactor 50. Since the bioreactor 7 generates heat of about 35 degrees Celsius to 40 degrees Celsius in the degassing apparatus 55 and heat is also generated in other aerobic fermenters, a large amount of evaporation occurs in the wastewater caused by these heats, thereby circulating wastewater. Continuous circulation is possible without some removal. If excessive amount is circulated, some may be discharged, but continuous circulation treatment is possible without separate removal of treated water unless there is a heavy load condition.

The piglet 1 having the fermentation tank 10 is configured for each piglet 1 and constitutes an outlet 6 in each piglet to be collectively collected into a solid-liquid separator 40 in one place. It is also possible to set it as the structure which recycles the last processed water back to each pig house 1, after making it process through 1 circulation fixation.

Although the present invention has been described as limited to pig yarn, it is a matter of course that the present invention may be applied to various livestock yarns such as barn and the like.

The bacterium used for the anaerobic treatment in the apparatus of the present invention described above may use, for example, akea, proakea, etc., and other microorganisms may be used.
