Abstract

The inflowed night soil is fermented and decomposed in culture medium layer that cultivates mixed germ on rice hulls with 1 m height from sand layer in water-purification tank. Because moisture is evaporated by generated fermentation heat, mixed germ is well multiplied. The remained waste water is repeatedly treated by complex layer that has gravel layer of 80 cm height and sand layer of 20 cm height. The used germ is sphaerotilus natans and zoogloea ramigera and Bacillus subtilis and Bacillus macerans.

Description

가축의 폐수 건식정화 처리방법Wastewater Dry Purification of Livestock

본 발명은 정화조의 중간높이로 자갈층과 모래층을 형성하고 모래윗층에 톱밥 또는 톱밥과 왕겨를 혼합물을 채워 보조배지로 하여 수균, 호기성균, 염기성균, 토양균 등을 배지에 접종 배양하고 이에 가축의 방뇨를 정화조에 유입시키어 발효균에 의하여 뇨의 유기질 물질을 분해함과 동시에 발효열에 의하여 증발 건조시키어 외부로 뇨 및 각종 폐수가 흘러 나감이 없이 정화처리함을 특징으로 한 가축뇨의 정화처리방법에 관한 것이다.The present invention forms a gravel layer and a sand layer at the middle height of the septic tank and fills the mixture with sawdust or sawdust and chaff on the upper sand to inoculate and incubate water, aerobic bacteria, basic bacteria, soil bacteria, and the like on the medium, A method of purifying livestock urine characterized in that urine is introduced into a septic tank to decompose organic matter in urine by fermentation bacteria, and evaporated and dried by fermentation heat to purify the urine and various wastewaters without flowing out. will be.

본 발명의 목적은 가축에서 흘러 나오는 뇨만을 정화처리하되, 발효균에 의한 분해작용과 발효에 의한 증발작용에 의하여 정화처리 함으로써 하천으로 뇨가 흘러 들어가는 일이 없어 폐수에 의한 하천오염을 방지하고 위생적으로 가축을 관리할 수 있게 하려는 데 있다.It is an object of the present invention to purify only the urine flowing from the livestock, by purifying by the decomposition effect of the fermentation bacteria and the evaporation effect of the fermentation so that no urine flows into the stream to prevent river pollution by waste water and sanitary It is to be able to manage livestock.

종래 가축사에서 하천을 오염시키는 폐수가 흘러 나오는 기본적인 문제점은 가축의 방뇨량 보다는 뇨 이외의 정수등이 분뇨에 혼합하여 폐수의 양을 증대시키는데 있고, 또 다른 문제점은 어떤 형식의 정화방법을 사용하든 간에 정화능력에 비하여 폐수방출량이 갈수록 증대되어 결국 정화되지 못한 폐수가 넘쳐 흘러 하수를 오염시키는 문제점이 있었다.The basic problem that the wastewater that contaminates rivers in conventional livestock companies is to increase the amount of wastewater by mixing water with manure rather than urine volume of livestock, and another problem is to use any type of purification method. Compared with the purification capacity, the amount of discharged wastewater increased gradually, resulting in a problem of contaminating the sewage by overflowing the uncleaned wastewater.

본 발명은 상기한 종래의 기본적인 문제점에 주안점을 두고 순수한 가축이 방뇨한 것만을 수집하고 소정의 크기로 축조된 정화조에의 중간 이하에는 자갈과 모래층을 형성하고 그 윗쪽에는 톱밥 또는 톱밥과 왕겨의 혼합물을 채워 보조배지로 하여 보조배지에 수균, 호기성균, 염기성균 및 토양균 등을 상기 정화조의 상, 중, 하층으로 분포되게 접종시키고 배뇨를 정화조에 유입하여 세균에 의한 발효작용에 의하여 뇨의 유기성분이 분해 처리되는 동시, 대부분의 습기는 발효열에 의하여 증발되고 극히 일부의 폐수만이 다시 토양균에 의하여 정화된 다음, 정화조 바닥의 지하에 스며들 수 있게 하여서 하천으로 배뇨가 흘러 들어가는 일이 없이 보다 위생적이고 무공해적으로 가축뇨 등을 처리할 수 있게 한 것이다.The present invention focuses on the above-mentioned basic problems, and collects only pure urine, and forms a layer of gravel and sand below the middle of the septic tank constructed to a predetermined size, and a mixture of sawdust or sawdust and chaff on the top. Inoculate germ, aerobic bacteria, basic bacteria, soil bacteria, etc. into the secondary medium distributed in the upper, middle, and lower layers of the septic tank and fill the urine into the septic tank to induce the organicity of urine by fermentation by bacteria. At the same time that the powder is decomposed, most of the moisture is evaporated by the fermentation heat and only a few of the wastewater is again purified by soil bacteria, allowing it to seep into the basement of the bottom of the septic tank so that urine does not flow into the stream. It is possible to handle livestock urine in a sanitary and pollution-free way.

본 발명을 실시예를 들어 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.

100마리의 돼지를 기를 때를 기준으로 1일 배뇨량은 약 400L 정도가 되므로 정화조의 크기는 뇨량의 약 20배 정도인 약 8t 정도로 폭 2m×길이2m×높이 2m 크기로 정화조를 축조한다.The amount of urination per day is about 400L per 100 pigs raised, so the size of the septic tank is about 8 tons, about 20 times the urine volume, about 2m wide x 2m long x 2m high.

정화조에는 바닥에서 80cm 높이로 자갈과 돌을 채우며 그위에 20cm 정도의 두께로 왕모래층을 적층 형성한다.The septic tank is filled with gravel and stone at a height of 80 cm from the bottom, and a layer of royal sand is formed thereon with a thickness of about 20 cm.

상기 왕모래층 상부의 공간에는 톱밥 또는 톱밥과 왕겨의 혼합물을 약 1m 높이로 채워서 혼합배지를 형성하고 이에 폐수의 자정(自淨)작용을 하는 수균, 호기성균, 염기성균, 토양균 등을 혼합 접종하여 배양한다.In the space above the king sand layer, a mixture of sawdust or a mixture of sawdust and chaff to about 1m high to form a mixed medium and mixed inoculation with water, aerobic bacteria, basic bacteria, soil bacteria, etc. to act as a self-cleaning of the wastewater Incubate.

본 발명에서 수균으로는 스패로티루스 나탄스(Sphaerotilus natans : KCTC : 1629)균, 또는 쥬글레오 라미게라(Zoogloea ramigera : KCTC : 2446)균을 사용하고 염기성균으로는 바시루스 서부티루스(Bacillus subtilus : KCTC : 1021)균을 사용하며, 또 염기성균으로는 바시루스 마세란스(Bacillus macerans : KCTC : 1822)균을 사용한다.In the present invention, as the bacterium, the bacterium Sphaerotilus natans (KCTC: 1629), or the bacterium Zoggloea ramigera (KCTC: 2446) is used, and as the basic bacterium, Bacillus subtius : KCTC: 1021) bacteria and Bacillus macerans (KCTC: 1822) bacteria are used as basic bacteria.

가축사의 배뇨관을 정화조 상부측으로 유도하여 배뇨가 정화조에 유입할 수 있는 적절한 조치를 취하여 둔다. 정화조에 유입된 뇨는 톱밥 또는 톱밥과 왕겨의 혼합물의 보조배지에 접종된 상기한 수균, 호기성균, 염기성균 및 토양균 등에 의하여 각층별로 유효한 발효작용으로 분해처리된다.The urine tube of the livestock company is led to the upper side of the septic tank, and appropriate measures are taken to allow urination to enter the septic tank. The urine introduced into the septic tank is decomposed by effective fermentation for each layer by water, aerobic bacteria, basic bacteria and soil bacteria inoculated into sawdust or auxiliary medium of a mixture of sawdust and chaff.

이때 발생되는 발효열에 의하여 수분이 증발되며 여러 균들이 잘 번식할 수 있는 상태로 유지되고 증발되고 남은 일부 폐수는 모래층과 자갈층에서 토양균에 의하여 마지막으로 완전하게 정화처리된 다음 지하에 스며든다.At this time, moisture is evaporated by the heat of fermentation, and various germs are kept in a good breeding state, and some of the remaining waste water is finally completely purified by soil bacteria in sand and gravel layers and then seeps underground.

이때 보조배지인 톱밥은 분해되지 않으므로 반영구적으로 사용할 수 있다. 또 극소량의 폐수가 바닥에 스며들더라도 토양균에 의하여 완전하게 정화처리되어 있으므로 지하가 오염될 우려가 없다.At this time, the auxiliary medium sawdust can be used semi-permanently because it is not decomposed. In addition, even if a very small amount of waste water penetrates the floor, it is completely purified by soil bacteria, so there is no danger of contaminating the underground.

즉 자연히 내리는 빗물에 의하여 지상의 각종 농약성분 등의 공해물질이 지하에 스며드는 것에 비하여 정화처리된 소량의 뇨가 지하에 스미는 공해는 경미하여 무시하여도 좋다.In other words, the pollution of the small amount of purified urine that can be collected in the basement is negligible as compared with the fact that the pollutants such as various pesticides on the ground penetrate underground due to the naturally occurring rainwater.

또 본 발명에서 정화에 시일이 걸리지 않고 항상 정화조가 발효상태로 있게 되어 보다 능률적으로 정화처리할 수 있으며 정화조의 설치 이후에는 유지비가 거의 들지 않아 경제적이다.In addition, in the present invention, the purification tank does not take a seal and is always in a fermentation state, so that the purification process can be more efficiently.

본 발명에서는 돼지뇨에 대하여 설명되어 있으나 소나 다른 가축의 뇨도 동일한 방법으로 정화처리할 수 있고, 기타 각종 폐수처리에도 유용하게 이용할 수 있다.Although the present invention has been described with respect to porcine urine, the urine of cattle or other domestic animals can be purified by the same method, and can be usefully used for other various wastewater treatments.
