Description
본 발명은 악취의 저감을 위한 생물탈취장치의 담체에 관한 것이다.The present invention relates to a carrier of a biodeodorizer for reducing odor.
더욱 상세하게는, 본 발명은 황화수소, 암모니아 등을 비롯한 복합악취를 제거하기 위하여 사용된 생물탈취장치의 담체로서 지렁이 분변토와 bark를 혼합 충진하여 보다 효과적으로 악취를 제거할 수 있도록 하는 생물탈취장치의 담체 및 그 제조방법에 관한 것이다.More specifically, the present invention is a carrier of a biological deodorizing device used to remove complex odors, including hydrogen sulfide, ammonia, etc., and a carrier of a biodeodorizing device which can effectively remove odors by mixing and filling earthworm feces and bark. And to a method for producing the same.
기존에 악취문제를 해결하기 위한 탈취기술로는 약액세정이나 활성탄 흡착 등 물리화학적 방법이 주로 사용되어 왔으나 높은 운전비용의 문제로, 90년대에 들어서는 토양탈취상 (soil biofilter) 위주의 생물탈취기술이 대체기술로 대체되기 시작하였다. 그러나 생물탈취기술 중에서도 가장 최근의 기술인 담체충전형 탈취상 (enclosed biofilter)은 유럽, 일본 등에서 널리 사용되고 있으며, 국내에서는 최근 도입되기 시작하는 초기단계에 있다. 담체충전형 탈취상(enclosed biofilter)의 경우 핵심기술은 충전 미생물담체, 탈취미생물 균주, 설계 및 운전기술로 구성되는데, 이 세가지 기술이 적절히 조화를 이룰 때 탈취효과를 극대화시킬 수 있게 된다.In order to solve the odor problem, physicochemical methods such as chemical liquid cleaning and activated carbon adsorption have been mainly used. However, due to the high operating cost, the biodeodorization technology mainly focused on the soil biofilter was introduced in the 1990s. It began to be replaced by alternative technology. However, the most recent technology of biodeodorization technology, enclosed biofilter, is widely used in Europe, Japan, etc., and is in the early stage of being recently introduced in Korea. In case of enclosed biofilter, the core technology consists of packed microbial carrier, deodorant microorganism strain, design and operation technology. When these three technologies are properly harmonized, the deodorizing effect can be maximized.
외국의 경우 각종 생물탈취용 미생물담체에 대한 연구가 진행되어 '80년대에는 경작토 등 토양 위주의 담체가 사용되어 오다가 '90년대 초반에는 토탄이끼(peat moss), 소나무 껍질 등 유기재료, '90년대 후반에는 슬래그, 세라믹, 특수 스폰지 등 무기재료가 개발되어 사용되고 있다. 미생물 균주로는Thiobacillus속을 중심으로 혼합악취까지 분해 가능한 여러 종의 균주가 분리되었다고 보고되고 있으나, 실제로 현장에 적용하여 성공한 사례는 미비한 단계로 계속적인 연구가 진행되고 있는 단계이다. 악취를 정량적으로 분석할 수 있는 분석능력을 갖추고 있으므로, 실험실규모 및 pilot 규모로 충분한 기초실험을 거쳐 설계인자 및 유지관리사항을 도출하여 탈취장치를 설계·상용화하는 단계이다.In the case of foreign countries, research on microorganism carriers for deodorizing various kinds of biodegradation has been conducted.In the '80s, soil-based carriers were used.In the early' 90s, organic materials such as peat moss and pine bark, ' In the late 90s, inorganic materials such as slag, ceramics and special sponges were developed and used. As microbial strains, several strains capable of degrading even mixed odors have been reported, mainly in the genus Thiobacillus . However, the successful cases of applying them to the field are still being studied. As it has the ability to analyze odor quantitatively, it is a stage to design and commercialize the deodorizer by deriving design factors and maintenance items through sufficient basic experiments on laboratory scale and pilot scale.
국내의 경우 미생물담체로서 한국건설기술연구원 및 국립환경연구원에서 각각 토탄(peat)/목탄 및 소나무 껍질을 이용한 생물탈취장치(biofilter) 실험을 수행하였으나 연구여건의 한계로 실용화 및 상용화가 되지 못하고 연구가 종료되었다. 여러 연구팀에 의해 탈취미생물이 분리되었으나, 혼합악취를 동시에 분해할 수 있는 균주의 개발사례는 보고되고 있지 않으며, 대부분 황화수소나 암모니아 등 단일악취에 대한 분해균주에 대한 연구가 진행되고 있는 단계이다. 악취성분을 정량적으로 평가할 수 있는 분석능력의 한계로 인해 검지관법, 관능법 또는 흡수법을 이용한 UV법 등 대부분의 연구가 간이측정장비를 이용하여 연구가 진행되었으며, 실험대상 악취 역시 분석이 용이한 황화수소, 암모니아 등 단일악취에 대해서 진행되었기 때문에, 수행된 연구결과를 복합취기가 발생하는 현장에 적용하기에는 한계가 있다. 이에 따라 체계적인 실험결과 및 설계인자를 토대로 한 탈취장치를 개발하는데 어려움이 있는 실정이다.In Korea, the Korea Institute of Construction Technology and the Korea Institute of Environmental Research conducted biofilters using peat / charcoal and pine bark as microbial carriers, respectively. Ended. Although deodorant microorganisms have been separated by various research teams, there have been no reported cases of development of strains capable of decomposing mixed odors at the same time, and most of them are in the process of decomposing strains for single odors such as hydrogen sulfide and ammonia. Due to the limitation of analytical ability to quantitatively evaluate malodorous components, most of the researches such as detection method, sensory method, or UV method using absorption method have been conducted using simple measuring equipment. Because of the progress of single malodors such as hydrogen sulfide and ammonia, there is a limit to applying the results of the research to the site where complex odor occurs. Accordingly, it is difficult to develop a deodorizer based on systematic experimental results and design factors.
본 발명의 배경을 간단히 보자면 대기보전법 제 66조에서는 생활악취시설 및 규제기준을 명시하고 2001년부터 본격규제를 실시하기 시작하였다. 동 조항에서는 생활악취시설의 소유자 또는 관리자가 악취배출허용기준을 준수하기 위한 조치를 취하도록 명시하고 있으며, 공정개선 또는 악취제거시설의 설계도, 공사계획, 악취처리방법 및 처리 효율 등을 환경부장관 또는 시·도지사에게 제출하도록 규정하고 있다. 하수종말처리시설 및 축산폐수공공처리시설 등의 환경기초시설이 생활악취 규제대상시설로 지정됨에 따라 각 지자체는 이러한 환경기초시설에 대한 악취관리대책 수립의 부담을 안게 되었다. 이러한 국내 여건에 맞추어 악취처리를 위한 생물 탈취 장치의 개발과 기술의 발전이 필요하게 되었다.Briefly, the background of the present invention, Article 66 of the Air Conservation Act specifies the living odor facilities and regulatory standards, and began implementing the full-scale regulation since 2001. The provision states that the owner or manager of a living malodorous facility should take measures to comply with the odor emission allowance standards, and the Ministry of Environment or the Minister of Environment or It is required to submit to the city and provincial governor. As environmental basic facilities such as sewage treatment facilities and livestock wastewater treatment facilities are designated as odor control facilities, each local government has been burdened with establishing odor management measures for such environmental basic facilities. In line with these domestic conditions, the development and development of technology for biological deodorizer for odor treatment has been required.
따라서, 본 발명의 목적은 악취의 저감을 위한 생물탈취장치의 처리 효율을 높이고 장기간의 운전을 가능하게 하며 장치의 설치시 저렴한 가격에 공급할 수 있는 생물탈취장치의 담체 제조방법을 제공 함에 있다. 본 발명의 다른 목적은 상기 제조방법에 따른 신규한 생물탈취장치의 담체를 제공하는 데 있다.Accordingly, it is an object of the present invention to provide a method for manufacturing a carrier for a biodeodorizer which can increase the treatment efficiency of the biodeodorizer for reducing odor, enable long-term operation, and can be supplied at a low price when the device is installed.

이하, 본 발명의 구체적인 구성 및 작용을 실시예를 들어 설명하지만, 본 발명의 권리범위가 이들 실시예에만 한정되는 것은 아니다.Hereinafter, the specific configuration and operation of the present invention will be described with reference to Examples, but the scope of the present invention is not limited only to these Examples.
실시예 1: 최적 조건의 담체 선택Example 1 Carrier Selection at Optimal Conditions
본 발명 생물탈취장치의 담체는 미생물 생장에 필요한 환경을 조성하는 것과 장기간의 운전을 위하여 낮은 압력손실(pressure drop), 높은 공극률(porosity), 긴 체류시간 등의 조건을 가져야 하므로 상기의 조건들을 만족시킬 수 있는 세 가지 담체를 선정하였다. 본 발명이 선택한 담체로는 유기담체인 지렁이 분변토와 bark, 무기담체로서 다공성 폐수처리용 여재를 선택하여 각 담체의 물리·화학적 성질을 조사하였다. 본 실시예에서 지렁이 분변토는 1.47 g-H2O/g-soil, bark는 1.75 g-H2O/g-bark의 수분함유율(water holding capacity)을 가지는 것을 사용하였다.Carrier of the present invention biodeodorant device satisfies the above conditions because it must have conditions such as low pressure drop, high porosity, long residence time to create the environment necessary for microbial growth and long-term operation Three carriers were selected. The carriers of the present invention were selected from earthworm fecal soil and bark, which are organic carriers, and porous wastewater treatment media as inorganic carriers. Earthworm fecal soil in this embodiment was 1.47 gH 2 O / g-soil, bark was used having a water holding capacity (water holding capacity) of 1.75 gH 2 O / g-bark.
실시예 2: 악취 처리율을 높이기 위한 담체의 충전 조건Example 2: Filling Conditions of Carrier for Improving Odor Treatment
상기 실시예에서 선택한 3가지 담체 재료를 이용하여 실험실 규모의 생물탈취장치(직경 10 cm, 높이 30 cm의 유리컬럼으로 제작)를 제작하고 본 발명 탈취장치의 압력손실을 실험하였다. 본 발명 생물탈취장치의 담체는 다음의 3가지 방법으로 충전하였다. 즉, 첫째 지렁이 분변토 만을, 둘째 지렁이 분변토와 bark를 4:1(v/v)의 비율로 혼합한 것을, 셋째 지렁이 분변토와 폐수처리용 여재를 4:1 (v/v)의 비율로 혼합한 것을 충전하였다. 또한 생물탈취장치의 에어 플로우(air flow)는 15 ∼ 190 m3/m2/h 으로 증가시키며 압력손실을 측정하였다.Using the three carrier materials selected in the above example, a laboratory scale biodeodorizer (10 cm in diameter, made of a glass column of 30 cm in height) was manufactured, and the pressure loss of the present invention deodorizer was tested. The carrier of the present invention biodeodorizer was filled by the following three methods. That is, only the first earthworm fecal soil is mixed with the second earthworm fecal soil and bark in the ratio of 4: 1 (v / v), and the third earthworm fecal soil and the wastewater treatment medium are mixed in the ratio of 4: 1 (v / v). Was charged. In addition, the air flow of the biodeodorizer (air flow) was increased to 15 ~ 190 m 3 / m 2 / h and the pressure loss was measured.
본 실시예에서 압력손실을 실험한 결과는 다음과 같다.The results of the pressure loss experiments in this example are as follows.
도 1은 지렁이 분변토 만으로 충전된 생물탈취장치 실험한 결과를 나타낸 것으로, 공극률은 57% 정도였으며, 에어 플로우를 증가시켰을 경우 공급률(flow rate)은 190 m3/m2/h 일때 약 35 mmH2O 정도의 압력손실을 보여주었다.Figure 1 shows the results of experiments on the biodeodorizer filled with earthworm fecal soil only, the porosity was about 57%, when the air flow increased the flow rate (flow rate) is about 35 mmH 2 at 190 m 3 / m 2 / h O pressure loss was shown.
도 2는 지렁이 분변토와 bark를 혼합한 생물탈취장치를 실험한 결과를 나타낸 것으로, 공극률은 60% 정도였으며, 도 1과 동일한 조건의 공급률에서 약 25 mmH2O 정도의 압력손실을 나타내어 도 1에서 보여지는 지렁이 분변토 만을 이용한 생물탈취장치에 비해 낮은 압력손실을 보여주었다.Figure 2 shows the results of experiments of the biodeodorizing device mixed with earthworm feces and bark, the porosity was about 60%, showing a pressure loss of about 25 mmH 2 O at the same feed rate as in Figure 1 The earthworm showed lower pressure loss than the biodeodorizer using only earthworm feces.
도 3은 지렁이 분변토와 폐수처리용 여재를 혼합한 생물탈취장치를 실험한 결과를 나타낸 것으로, 도 1, 2 와 동일한 공급률에서 압력손실은 30 mmH2O 정도로 나타났다. 지렁이 분변토 만을 충진한 장치와 비교시 약간 낮은 압력손실을 보여주지만, 지렁이 분변토와 bark를 혼합하여 충진한 장치보다는 높은 압력손실을 보였다.Figure 3 shows the results of experiments of the biological deodorizing device mixed with the earthworm fecal soil and wastewater treatment media, the pressure loss was about 30 mmH 2 O at the same feed rate as in FIGS. The pressure loss was slightly lower than the device filled with the earthworm fecal soil, but the pressure loss was higher than the device filled with the earthworm fecal soil and bark.
상기 실험 결과에 따르면, 지렁이 분변토와 bark를 혼합하여 충진한 경우 공극률의 증가로 인하여 낮은 압력손실을 얻을 수 있었으며, 또한 도 2에 나타난 바와 같이 체류시간을 길게 하여 악취의 처리 효율을 높일 수 있었다. 즉, 지렁이 분변토와 bark를 4:1 (v/v)의 비율로 혼합하는 방법이 처리 효율을 가장 높일 수 있는 최적 조건임을 알 수 있었다.According to the above test results, when the earthworm fecal soil and bark were mixed and filled, a low pressure loss was obtained due to an increase in porosity, and as shown in FIG. 2, the residence time was increased to increase the treatment efficiency of the odor. In other words, it was found that the method of mixing the earthworm fecal soil and bark at a ratio of 4: 1 (v / v) was the optimum condition for the highest treatment efficiency.
실시예 3:실험실 규모 생물탈취장치를 이용한 담체의 실용성 검증 Example 3: Verification of the practicality of the carrier using the laboratory scale biodeodorizer
상기 실시예 2에서의 실험 결과를 바탕으로 실험실 규모 (직경 10 cm, 높이 30 cm의 유리컬럼으로 제작)의 본 발명 생물탈취장치를 제작하여 악취(황화수소)의 처리 실험을 수행하였다. 1차 황화수소 처리 실험은 다음의 3가지 방법으로 충진된 생물탈취장치를 사용하였다. 첫째 지렁이 분변토 만을, 둘째 bark 만을, 셋째 지렁이 분변토와 bark를 4:1(v/v)의 비율로 혼합하여 충진한 각각의 생물탈취장치를 이용하여 실험하였다. 그러나 bark 만을 충진한 경우, 황화수소의 처리 효율이 매우 낮아 대부분의 황화수소가 그대로 배출되었다. 따라서 2차 황화수소 처리 실험에서는 지렁이 분변토 만을 충진한 생물탈취장치와 지렁이 분변토와 bark를 4:1 (v/v)의 비율로 혼합한 생물탈취장치를 이용하여 실험하였다. 지렁이 분변토는 미생물 성장 및 운전에 가장 적합한 수분함량(moisture content)을 60%로 하여 충진하였다. 황화수소의 air flow는 22.92 m3/m2/h으로 하였고, 주입농도는 14.86±2.67 ppmv로 하였다. 황화수소의 배출농도는 0.33±0.33 ppmv로 관찰되었다.Based on the experimental results in Example 2, the present invention biodeodorizing device of the laboratory scale (10 cm in diameter, made of glass column of 30 cm in height) was produced to perform a treatment experiment of malodor (hydrogen sulfide). In the first hydrogen sulfide treatment experiment, a biodeodorizer packed with three methods was used. The first earthworm feces only, the second bark only, and the third earthworm feces and bark were mixed using a 4: 1 (v / v) ratio of each biodeodorizing device was tested. However, when only bark was charged, most of the hydrogen sulfide was discharged as it was very low. Therefore, in the second hydrogen sulfide treatment experiment, the experiment was conducted by using the biodeodorizer which filled the earthworm fecal soil only and the biodeodorizer which mixed the earthworm fecal soil and bark at the ratio of 4: 1 (v / v). Earthworm fecal soils were filled with a moisture content of 60%, which was most suitable for microbial growth and operation. The air flow of hydrogen sulfide was 22.92 m 3 / m 2 / h and the injection concentration was 14.86 ± 2.67 ppmv. The hydrogen sulfide emission concentration was observed to be 0.33 ± 0.33 ppmv.
도 4는 2차 황화수소 처리 실험의 결과를 나타낸 것으로서 주입된 황화수소의 제거율은 2.56±0.43 g/m3/h으로 관찰되었다. 분변토에는 많은 미생물이 존재하고 bark는 처리 효율이 그리 높지 않으므로, 분변토 만을 충진한 장치가 단일 부피당 보다 많은 분변토를 보유하고 있어 높은 처리 효율을 보일 것이라 기대하였다. 그러나 지렁이 분변토와 bark를 혼합하여 충진한 생물탈취장치가 좀더 높은 처리 효율을 보였다. 이는 지렁이 분변토에 bark를 혼합할 경우 공극률의 증가를 가져오며 악취와 충진물과의 반응시간이 길어져 분변토 만을 충진한 장치에 비해 높은 처리 효율을 보인 것으로 판단된다.Figure 4 shows the results of the second hydrogen sulfide treatment experiment, the removal rate of the injected hydrogen sulfide was observed to 2.56 ± 0.43 g / m 3 / h. Since fecal soils contain a lot of microorganisms and bark is not very efficient, it is expected that the device filled with fecal soils will have more fecal soil per single volume. However, the biodeodorizer packed with earthworm fecal soil and bark showed higher treatment efficiency. When bark is mixed with earthworm fecal soils, the porosity is increased and the reaction time between odor and fillers is long, and it is considered that the treatment efficiency is higher than that of the device filled with fecal soils only.
도 5는 도 4에서 황화수소 처리 실험을 하는 동안 생물탈취장치의 압력손실과 담체의 pH 변화를 나타낸 그래프이다. 도 5에서 pH 변화를 보면 지렁이 분변토만 충진한 장치와 지렁이 분변토와 bark를 혼합한 장치 모두 pH 7.86±0.11으로 중성의 안정된 값을 나타냈다. 즉, 생물탈취장치의 장기 운전시 발생할 수 있는 담체내 pH 저하로 인한 처리 효율의 감소를 해결할 수 있도록 한다. 도 5에서 상기 생물탈취장치들의 압력손실을 비교해 보면, 지렁이 분변토 만을 충진한 장치는 3.91±0.53 mmH2O, 지렁이 분변토와 bark를 혼합한 장치는 3.66±0.56 mmH2O의 수치를 나타냈다. 상기 두 생물탈취장치들은 모두 매우 낮은 압력손실을 나타냈으며 장기간 운전하여도 압력손실이 급증하지는 않았다.5 is a graph showing the pressure loss of the biodeodorizer and the pH change of the carrier during the hydrogen sulfide treatment experiment in FIG. In the pH change in FIG. 5, only the earthworm fecal soil-filled device and the earthworm fecal soil-bark mixed device showed a neutral stable value of pH 7.86 ± 0.11. That is, it is possible to solve the reduction in treatment efficiency due to the pH lowering in the carrier that can occur during long-term operation of the biodeodorizer. Comparing the pressure loss of the biodeodorizer in Figure 5, the device filled with earthworm fecal soil only 3.91 ± 0.53 mmH 2 O, the mixture of earthworm fecal soil and bark showed a value of 3.66 ± 0.56 mmH 2 O. Both biodeodorizers showed very low pressure loss and the pressure loss did not increase rapidly even after long-term operation.
실시예를 통하여 설명한 바와 같이, 본 발명은 생물탈취장치의 핵심 기술중 하나인 담체 재료에 관한 것으로서 지렁이 분변토와 bark를 선택하여 제조됨으로써, 미생물의 성장과 활동에 적합한 최적의 환경을 제공할 수 있는 효과가 있고, 공극률을 증가시키고 낮은 압력손실과 체류시간을 길게 하여 더욱 높은 처리 효율을 제공하는 효과가 있다. 또한, 본 발명은 생물탈취장치의 처리 효율을 높이고 장기간의 운전을 가능하게 하며 장치의 설치시 저렴한 가격에 공급할 수 있으므로 환경산업상 매우 유용한 발명인 것이다.As described through the embodiment, the present invention relates to a carrier material which is one of the core technologies of the biodeodorizer, and is manufactured by selecting the earthworm fecal soil and bark, thereby providing an optimal environment suitable for the growth and activity of microorganisms. It has the effect of increasing the porosity and lowering the pressure loss and residence time to provide higher treatment efficiency. In addition, the present invention is a very useful invention for the environmental industry because it can increase the treatment efficiency of the biodeodorizing device, enable long-term operation and can be supplied at a low price when installing the device.
