Description

가축분뇨 액비의 부숙도 측정방법{Measuring method for fermentation degree of liquid Fertilizer}[0001] The present invention relates to a method for measuring the degree of composting of a liquid waste of a livestock manure,

본 발명은 가축분뇨 액비의 부숙도 측정방법에 관한 것으로서, 더욱 상세하게는 가축분뇨 액비에 적합한 종자발아법을 제시하고 부숙도 측정기와 연계하여 물리적이고 생물학적으로 정확하게 부숙도를 측정할 수 있는 가축분뇨 액비의 부숙도 측정방법에 관한 것이다. The present invention relates to a method for measuring the degree of composting of livestock manure juice, more particularly, to a method of seed germination suitable for the manure effluent ratio and a method of measuring the degree of composting physically and biologically, The present invention relates to a method for measuring the degree of composting of a substrate.

돈분, 우분, 계분과 같은 가축에서 배출된 분뇨(이하, '가축분뇨'라 함)를 발효시키지 않은 상태로 농지에 살포한 경우에는 가축분뇨에서 발생하는 악취와 유해가스로 인해 오히려 농작물의 생장을 저해하게 된다.When manure discharged from livestock such as swine, fowl and stalks (hereinafter referred to as "livestock manure") is sprayed on farmland without fermenting, the odor and harmful gas generated from livestock manure may cause the growth of crops .

따라서, 농가에서 수거된 가축분뇨는 미생물에 의해 부숙시킨 다음, 후속공정을 통해 고액 분리되어 고형물은 퇴비로 이용되며 액상물은 액비로 토양에 환원되어 이용된다.Therefore, the livestock manure collected from the farmhouse is composted by microorganisms, and then solid-liquid is separated through a subsequent process, and the solid material is used as compost, and the liquid material is reduced to the soil by the liquid pot.

여기서, 부숙이란 식물이 흡수하기 좋은 물질로 변화시키는 것을 의미하고, 가축분뇨 액비가 잘 부숙되면 식물이 토양에 환원된 가축분뇨 액비를 잘 흡수하여 영양분으로 사용할 수 있는 것이고, 가축분뇨 액비가 잘 부숙되지 않으면 식물이 토양에 환원된 가축분뇨 액비를 영양분으로 잘 흡수하지 못한다는 것을 의미하기 때문에, 가축분뇨 액비를 토양에 환원시켜 식물이 영양분으로 이용할 수 있도록 하기 위해서는 가축분뇨 액비의 부숙도를 판단해야 한다.Here, composting means changing the material into a material that the plant can absorb, and when the livestock manure juice is well composted, the plant can absorb the livestock manure juice reduced to the soil and use it as a nutrient. It is necessary to determine the degree of composting of livestock manure juice in order to reduce the amount of livestock manure juice to soil so that the plant can utilize it as a nutrient because it means that the plant does not absorb the nutrient- do.

가축분뇨 액비의 부숙도 판단방법은 크게 기계적 판단방법과 생물적 판단방법으로 나뉠 수 있다.The method of judging the degree of composting of livestock manure liquid can be divided into mechanical judgment method and biological judgment method.

기계적 판단방법은 암모니아(NH3) 및 황화수소(H2S)의 가스농도와 분광광도계(分光光度計)를 이용한 색도 측정방법으로, 부숙 정도에 따라 미숙, 중숙, 부숙(완숙)의 세단계로 구분된다.The mechanical determination method is a chromaticity measurement method using a gas concentration of ammonia (NH 3 ) and hydrogen sulfide (H 2 S) and a spectrophotometer (spectrophotometer). The method is classified into three stages of immature, Respectively.

생물적 판단방법은 종자발아율을 이용한 측정방법으로, 일명 종자발아법이라 한다. 종자발아법이란 식물의 종자가 액비에 의해 얼마나 잘 발아하는지를 검사하여 백분율로 나타내는 것으로서, 부숙이 잘되면 그만큼 식물이 성장하는데 도움을 주는 밑거름이 되기 때문에 가축분뇨액비가 미숙단계에서 50％ 이하의 종자발아율을 갖고, 중숙단계에서는 50∼70％의 종자발아율을 가지며, 완숙단계에서는 70％ 이상의 종자발아율을 갖는다.The biological judgment method is a measurement method using the seed germination rate, which is called a seed germination method. The seed germination method refers to the percentage of germination of plant seeds by the liquid fertilizer. If the fertilizer is well fertilized, it helps the plant to grow. Therefore, when the fertilizer manure is less than 50% , Seed germination rate of 50 to 70% in the ripening stage, and seed germination rate of 70% or more in the ripening stage.

통상적으로, 액비의 부숙도 측정방법은 기계적 측정법 검사 후에도 냄새에 의한 부숙이 의심될 때에는 종자발아법으로 검사한다.Normally, the method of measuring the degree of composting is checked by the method of seed germination after suspicion of composting due to odor even after mechanical examination.

하지만, 액비의 기계적 부숙도에 관한 측정은 정확도가 낮은 문제점이 있다.However, there is a problem that the accuracy of measurement of the mechanical compost of the liquid is low.

그리고, 기계적 측정법의 보완으로 제시된 종자발아법 또한, 퇴비에서 이용되는 종자발아법을 그대로 적용하였기 때문에 액비에는 적합하지 않은 문제점이 있다. Also, the seed germination method proposed by supplementing the mechanical measurement method has a problem that it is not suitable for the liquid fertilizer because the seed germination method used in the compost is applied as it is.

따라서, 본 발명의 목적은 액비 부숙도 평가지표 즉, 액비발아지수(Liquid Fertilizer Germination Index; LFGI)를 도출하여 그에 적합한 가축분뇨 발효액비에 대한 종자발아법을 제시하고, 부숙도 측정기와 연계하여 액비의 부숙도를 측정하는 방법을 제공하는 데 있다. Accordingly, it is an object of the present invention to provide a seed germination method for extracting liquid fertilization index, i.e., Liquid Fertilizer Germination Index (LFGI), suitable for the method of the present invention, And a method for measuring the degree of composting.

이와 같은 목적을 달성하기 위한 본 발명의 가축분뇨 액비의 부숙도 측정방법은, (1) 액비의 부숙도 시료를 채취하는 단계, (2) 채취한 액비 시료의 희석배수를 산정하여 액비를 희석하는 전처리 단계, 및 (3) 희석한 액비 시료의 종자발아율을 측정하여 액비의 부숙도를 결정하는 단계를 포함한다.In order to achieve the above object, the method for measuring the degree of composting of livestock manure solution according to the present invention comprises the steps of (1) collecting a compost sample, (2) diluting the liquid pot by diluting the collected liquid pot samples, A pretreatment step, and (3) a step of measuring the seed germination rate of the diluted liquid fertilizer sample to determine the degree of composting of the liquid fertilizer.

본 발명의 가축분뇨 액비의 부숙도 측정방법은, 가축분뇨 액비에 대한 원료 희석 배율을 산정하여 종자발아법에 적용하므로써, 액비 부숙도를 정확하게 측정할 수 있다.The method of measuring the degree of composting of the livestock manure solution according to the present invention can accurately measure the liquid composting degree by calculating the dilution ratio of the raw material to the liquid manure ratio and applying it to the seed germination method.

더 나아가, 퇴비·액비 분석의 객관성 및 신뢰성 향상을 도모하고 양질의 액비를 살포할 수 있어 액비 활용을 증대시키고 갈수록 증가하는 가축분뇨의 자원화 비율에 효율적으로 대응할 수 있게 된다.Further, objectivity and reliability of the compost and liquid analysis can be improved, and the liquid fertilizer can be dispensed with high quality, thereby increasing the utilization of the liquid fertilizer and efficiently responding to the increasing resource conversion rate of the animal manure.

도면은 본 발명에 따른 가축분뇨 액비의 부숙도 측정방법을 나타내는 공정도이다.1 is a process diagram showing a method for measuring the degree of composting of a livestock manure solution according to the present invention.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 기술하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도면은 본 발명에 따른 가축분뇨 액비의 부숙도 측정방법의 공정도로, 액비의 기계적 부숙도 측정단계(S1), 전처리 단계(S2), 종자발아법 검사단계(S3), 그리고 마지막으로 부숙결정단계(S4)로 이루어지게 된다.The figure shows the process of measuring the degree of composting of livestock manure solution according to the present invention. The mechanical composting step (S1), the pretreatment step (S2), the seed sprouting method step (S3) and finally the composting step S4).

첫째, 액비의 기계적 부숙도 측정단계(S1)는 가축분뇨 액비 시료의 악취 가스농도를 측정하고, 가축분뇨 액비 시료의 광투과율로 색도를 측정하여 색 정보 및 악취가스 정보를 분석하여 액비 부숙도를 1차적으로 판단한다.First, the mechanical composting step (S1) of the liquid manure measures the odor gas concentration of the livestock manure liquid sample, and the chromaticity is measured by the light transmittance of the livestock manure liquid sample to analyze the color information and the odor gas information, It is judged primarily.

둘째, 전처리 단계(S2)는 액비 부숙도 판단의 중요 요인인 종자발아율을 기준으로 액비 부숙도를 측정하기에 앞서 가축분뇨 액비 시료를 침전물이 없도록 완전히 섞어준 후 희석한다.Secondly, the pretreatment step (S2) is to thoroughly mix livestock manure liquid samples so that there is no sediment, and then dilute them before measuring the liquid manure degree based on the seed germination rate, which is an important factor in determining the liquid manure degree.

본 발명에서는 다음의 돈분뇨 퇴비화 공정에서 수분함량별로 수분조절재의 소요량 계산 방식을 이용하여 '원료 희석배율'을 산정하였다.In the present invention, the 'dilution factor of raw material' was calculated by using the method of calculating the required amount of the moisture control material according to the water content in the following manure composting step.

수분조절재소요량(㎏)=생분뇨량(㎏)×{(생분뇨수분함량(％)-목표수분(x％))/(목표수분(x％)-수분조절재수분(25％))}Water content (%) - Target water (x%) / (Target water (x%) - Moisture control rehydration (25%))}

가. 돈분뇨 1㎏당 수분함량 90％일 경우, 퇴비화 원료의 목표수분을 65％로 설정시 원료의 희석배율은, end. When the moisture content per 1 kg of waste manure is 90%, when the target moisture content of the composted raw material is set to 65%, the dilution factor of the raw material is,

수분조절재소요량(㎏) = 1㎏ × (90％-65％)/(65％-25％) = 0.625㎏The amount of moisture control material (kg) = 1 kg × (90% -65%) / (65% -25%) = 0.625 kg

희석배율 = 총량/시료량 = 1.625/1 = 1.625Dilution magnification = total amount / sample amount = 1.625 / 1 = 1.625

나. 돈분료 1㎏당 수분함량 73.9％일 경우, 퇴비화 원료의 목표수분을 65％로 설정시 원료의 희석배율은,I. When the water content per 1 kg of the poultry material is 73.9%, when the target moisture of the composted raw material is set to 65%, the dilution factor of the raw material is,

수분조절재소요량(㎏) = 1㎏ × (73.9％-65％)/(65％-25％) = 0.2225㎏The amount of moisture control material (kg) = 1 kg × (73.9% -65%) / (65% -25%) = 0.2225 kg

희석배율 = 총량/시료량 = 1.2225/1 = 1.2225Dilution magnification = total amount / sample amount = 1.2225 / 1 = 1.2225

다. 돈분료 1㎏당 수분함량 95％일 경우, 액비화 원료의 목표수분을 65％로 설정시 원료의 희석배율은,All. When the water content per 1 kg of the poultry feed is 95%, when the target water content of the liquified raw material is set to 65%, the dilution ratio of the raw material is,

수분조절재소요량(㎏) = 1㎏ × (95％-65％)/(65％-25％) = 0.75㎏The amount of moisture control material (kg) = 1 kg × (95% -65%) / (65% -25%) = 0.75 kg

희석배율 = 총량/시료량 = 1.75/1 = 1.75Dilution magnification = total amount / sample amount = 1.75 / 1 = 1.75

따라서, 목표 수분함량 65％인 상기 가, 나, 다에서 도출된 '원료 희석배율'들의 평균값인 1.5325를 원료 희석배율 고정지수로 설정한다.Therefore, the raw dilution factor fixing index is set to 1.5325, which is an average value of the " raw dilution factors " derived from the above and below with a target moisture content of 65%.

또한, 본 발명에서는 다음의 퇴비 종자발아법의 전처리 방법에 액비를 적용하여 '시료 희석배율'을 산정하였다.In the present invention, the 'sample dilution magnification' was calculated by applying the liquid fertilizer to the pretreatment method of the following compost seed germination method.

100㎖ 기준으로 퇴비시료의 량은, 5×100 / 100-수분함량, 이때 시료의 총량은 시료(g)+증류수(100㎖)가 된다.The amount of the compost sample on the basis of 100 ml is 5 × 100/100-moisture content, and the total amount of the sample is (g) + distilled water (100 ml).

이를 액비에 적용시 수분함량 95％(고형물함량(TS) 5％)로 가정하면, 100㎖ 기준 액비시료의 량은, 5×100 / 100-95 = 100㎖이고, 이때 시료의 총량은 '100㎖+증류수 100㎖=200㎖가 된다.Assuming that the water content is 95% (solids content (TS) 5%) when applied to the liquid, the amount of the 100 ml standard liquid ratio sample is 5 × 100 / 100-95 = 100 ml, Ml + distilled water 100 ml = 200 ml.

따라서, 수분함량 95％(TS 5％) 액비시료의 희석배율은 총량/시료량 = 200/100 = 2가 된다.Therefore, the dilution magnification of the liquid sample at a moisture content of 95% (TS 5%) becomes the total amount / sample amount = 200/100 = 2.

즉, 고형물 함량에 따른 100㎖ 기준 액비 시료의 희석배율은 다음의 표와 같다.In other words, the dilution ratio of 100 ml standard liquid ratio sample according to the solids content is shown in the following table.

구분division TS 5％TS 5% TS 4％TS 4% TS 3％TS 3% TS 2％TS 2% TS 1％TS 1% 희석배수Dilution factor 2배Twice 1.8배1.8 times 1.6배1.6 times 1.4배1.4 times 1.2배1.2 times

액비 전처리 최종 희석배수는 액비 시료 희석배율과 원료 희석배율 고정지수의 곱으로 산출된다.The final dilution factor of the liquid pretreatment is calculated as the product of the liquid sample dilution factor and the fixed dilution factor of the raw material.

일예로, 고형물 함량이 5％이고, 수분함량이 95％인 액비의 경우 시료 희석배율이 2배이므로, 여기에 원료 희석배율 고정지수인 1.5325를 곱하면 최종 희석배수는 3.1배가 되게 된다. For example, for liquids with 5% solids and 95% moisture, the sample dilution factor is doubled, so multiplying the raw dilution factor by 1.5325 will result in a final dilution factor of 3.1.

따라서, 최종 희석배수는 고형물함량 5％에서 3.1배, 4％에서 2.8배, 3％에서 2.5배, 2％에서 2.1배, 1％에서 1.8배가 되게 된다.Thus, the final dilution factor will be 3.1 times, 4% to 2.8 times, 3% to 2.5 times, 2% to 2.1 times, and 1 to 1.8 times the solids content of 5%

종자발아법을 시행하기에 앞서, 가축분뇨 액비 시료를 최종 희석배율로 희석하는 전처리 단계를 수행한다.Prior to the seed germination procedure, a pretreatment step is performed to dilute the livestock manure liquid sample to the final dilution ratio.

셋째, 종자발아법 검사단계(S3)는, 배양접시(Petri Dish)에 희석시킨 액비 시료를 가한 후 무 종자를 사용하여 발아율과 뿌리길이를 구하여 발아지수(GI)를 계산한다. Third, in the seed germination test step (S3), germination index (GI) is calculated by adding germicidal diluted to Petri Dish and then determining germination rate and root length using seedless seeds.

발아지수(GI) 계산은, GI=GR×RE/100으로, 여기서, GR=(발아율/Control 발아율)×100이고, RE=(뿌리길이/Control 뿌리길이)×100이다.The germination index (GI) calculation is GI = GR 占 RE / 100 where GR = (germination rate / germination rate of control) 占 100 and RE = (root length / control root length) 占 100.

상기 표 3의 결과를 보면, 18개 액비샘플 기계적 부숙도 측정결과 부숙 11개, 중숙 6개, 미숙 1개로 측정되었다. 무희석 종자발아법의 경우 부숙 판정된 11개 샘플 중 2개 샘플만 각 발아지수(GI)가 70 이상으로 측정되었으며(충북1 GI 74.2, 충남1* GI 71.4), 9개 샘플은 모두 발아지수(GI) 70 이하로 나타났다. 퇴비종자발아법의 경우 부숙 판정된 11개 샘플 중 6개 샘플이 각 발아지수(GI) 70 이상으로 측정되었으며, 본 발명의 희석 전처리 액비종자발아법(LFGI)의 경우 부숙 판정된 11개 샘플 중 10개가 각 발아지수(GI) 70 이상으로 측정되었다. 전남2 샘플의 경우 부숙 판정임에도 불구하고 모두 발아지수(GI) 0으로 측정되었다.As shown in Table 3 above, the results of measuring the mechanical compost of 18 samples of liquid samples were measured as 11 compost, 6 mature, 1 immature. In the case of the non-diluted seed germination method, only two samples out of the 11 samples that were determined to be in the composted state had a germination index (GI) of 70 or more (Ch 1, GI 74.2, Chungnam 1 * GI 71.4) GI) of 70 or less. In the compost seed germination method, six out of eleven samples determined to be composted were measured to have a germination index (GI) of 70 or more. In the case of the diluted pretreatment liquid fertilization method (LFGI) of the present invention, ten out of eleven samples Each germination index (GI) was measured above 70. In Jeonnam 2 samples, germination index (GI) was measured to be zero even though it was a compost determination.
