Description

TECHNICAL FIELD The present invention relates to a liquid fertilizer system for livestock manure and a method for processing liquid fertilizer using the same,

The present invention relates to a liquid fertilizer system for livestock manure that treats manure such as pigs and cattle to produce organic fertilizer, and a method for producing liquid fertilizer of livestock manure using the same.

In general, as livestock manure (or livestock manure) grows with the economic growth and the demand for livestock products increases, the number of livestock livestock increases as the size of the livestock increases, and the amount of manure generated in single livestock facilities is increasing gradually. This manure contains various organic compounds and fertilizers such as potassium phosphate, which are used as fertilizer in crops and fruit trees. However, since the amount of fertilizer is too much, .

The above-mentioned animal manure is left untreated, causing bad odors, becoming a habitat for various insects such as parasitic mosquitoes, and aggravating the living environment of the rural area.

In addition, the quality characteristics of such manure vary greatly depending on storage period, type of housing, and type of feed, and even in the same breeding facility, the quality varies depending on time, season, and collection method. And toxic substances may be contained due to the heavy metals contained in the feed and the residues of disinfectants due to disinfection.

On the other hand, livestock manure livestock refers to a collection of livestock manure that is collected from a livestock raising process, a mixture of urine and cleaning water, or other livestock manure processing (anaerobic fermentation liquor, property fermented liquid manure) It refers to a liquid substance which is stored at a certain period of time to be inhabited and killed by pathogenic microorganisms, oviposition, weed seeds,

These liquids include nitrogen, phosphorus, and potassium, which are necessary for crop growth, as well as trace elements such as calcium, magnesium, sodium, iron, manganese, and molybdenum.

However, the application of livestock manure to livestock farming has not been put to practical use until now, but it is a fact that it has various advantages in domestic circumstances.

Liquefaction can minimize the problems of purchasing the raw materials by processing the livestock manure into the liquid phase, as well as produce the alternative fuels incidentally and can greatly reduce manure disposal costs from composting.

However, there is a disadvantage that it is impossible to carry out long-distance transport of liquefied petroleum, and the handling of liquefied petroleum is relatively disadvantageous compared to composting, and it is practically impossible to sell manure.

Nevertheless, livestock manure liquefaction is advantageous not only in the manure of the slurry house but also in the effluent water after the purification treatment. Urinal wastewater in the housing has a limitation in satisfying current water quality regulation standards at the time of discharge after purification treatment. Therefore, livestock farmers who installed purification treatment facilities can also say that liquefaction of effluent water after purification is a very desirable means in terms of environment.

In recent years, there have been proposed various methods of using livestock manure by recycling the livestock manure. However, due to the nature of the livelihood, the ingredients and the degree of composting are not constant, and a large-scale tank Inefficient parts to install are pointed out as problems.

As described above, there are two methods of producing livestock manure using a microorganism, namely, a method using aerobic microorganisms and a method using anaerobic microorganisms. The former has advantages such as rapid liquid fertilizing, high temperature and death of harmful bacteria and weed seeds, but the value of fertilizer is somewhat lower and there is a disadvantage of using excessive power. On the other hand, the method using anaerobic microorganisms has the advantage of producing a fertilizer having a low power ratio and a high organic value, but has a problem of complaints due to a relatively long treatment time and odor problem. It is generally known that the aerobic system is faster than the anaerobic system.

However, in the conventional treatment method of high concentration organic wastewater by the continuous batch type liquid erosion method, in order to lower the load of organic matter in the process of treating livestock manure as a high concentration organic wastewater, a coagulant is injected in a pretreatment process and a separate dehydration process has to be carried out , A high concentration organic waste solution was injected into the liquid erosion bath to generate heat due to the decomposition of organic matter, thereby causing a problem that the temperature of the liquid erosion tank is increased or the dissolved oxygen is lowered due to the temperature rise. Also, And the livestock manure that can be converted into a resource can be cleaned without recycling, the capacity of the treatment facility is increased and the sludge is also generated, resulting in uneconomical problems.

In the conventional liquefaction treatment system, a method of deodorizing odor generated in each tank by using chemicals is used.

However, the above-mentioned method has a problem that wastewater is generated by using chemicals, and the wastewater needs to be entrusted to a specialized company in order to treat the wastewater.

At this time, the coupling state, the coupling position, and the like of the raw water transfer pump are not limited to a great extent and may have a commonly used coupling method or structure.

According to the present invention, soil microorganisms are supplied to the raw water supplied to the mixing and aeration tank (140) and the dehydrating filtrate, and then subjected to an aeration step of aeration for 88 to 120 hours. The aeration step reduces the levels of SS / BOD / COD present in the raw water 40 by the supplied soil microbes and microbubbles generated by the microbubble generator 145, and decomposes heavy metals and organic matter. At this time, decomposition of heavy metals and organic matters is accelerated by the decomposition of organic matter of the soil microorganisms and the action of micro nano foam collapse due to micro bubbles. The values of SS / BOD / COD are greatly reduced.

 The soil microorganisms are effective for soil improvement, promotion of decomposition of organic matter, promotion of absorption of amniotic fluid, and prevention of pest insect.
