As a part of basic investigation and research the present condition and characteristics of livestock wastewater production in Sogwipo City is accessed. Based on the current data a trend of the livestock wastewater production for the furture is predicted. This is our purpose to facilitate this report as a basic guide-line for the furture livestock wastewater treatment. The result of this study are summarized as follows : 1. Breeding households of livestocks (swine. beef cattle, chicken) decrease every year, but the number of heads per household are increased each year. 2. BOD-loading per day of beef cattles wastewaters investigated 59.2kg. and pollution loadings are suspected 38.3 BODkg/day at 2001 year. 3. The quanity of swine wastewaters were counted 12.4ℓ/head·day, BOD-loadings were reached 45.6kg and suspected same values at 2001 year

In this research, We have studied and analysed new variable referenm about the removal method of nitrate in ground water using drinking water. That method using extra basic exchange resine was the most suitable to the removal of nitrate. As a result of this study, the following mclusions have been reached. 1. When a cancentration of nitrate ion and sulfate ion is similar, even though a general extra basic resine(exchange equvalent:1.3-1.4eq/ l -R) was used the exchange load showed is a little difference with respect to a nitrate selective resine. 2. In case of downflow regeneration method, a treatment water was stabbed at above 200gNaCl/l -R of regeneratin level. 3. When a resine level is 200gNaCl/l -R, tube fbw exchange equivalent was 995meq/l -R. 4. As a result of analysing a raw water which was 30mgNO_(3)/l by means of this ion exchange process the removal efficiency was more than 80 percent.

허목,강진영 유기성자원학회 2004 유기물자원화 Vol.12 No.1

This study was performed : 1) to find the suitable HRT(hydralic retention time), 2) to evaluate the effects of the ratio of mixing/aeration time and injection time of acetic acid, for the removal of organics, nitrogen and phosphorus in swine wastewater by SBR(sequencing batch reactor process), which is one of the biological treatment process.The result of this study were summarized as follows : (1) As the ratio of mixing/aeration time was higher, NH4+-N removal efficiency was increased and it was increased with increasing injection time of acetic acid because nitrification was affected by denitrification microbes propagation when injection time of external carbon soruce was shorted. T-N removal efficiency was increased with increasing the ratio of mixing/aeration time and injection time of acetic acid. (2) The T-P removal efficiency showed a great difference in each operating condition, and it was increased with increasing the ratio of mixing/aeration time increased and when the injection time of acetic acid was shorted because denitrification was done with effect by denitrification microbes propagation. (3) The highest removal efficiency of organic and nitrogen were obtained by the operating condition of Run 4-1(the ratio of mixing/aeration time : 16.5/5.5, injection time of acetic acid : 15hours) and T-P were obtained by the operation condition of Run 4-2(the ratio of mixing/aeration time : 16.5/5.5, injection time of acetic acid : 3hours), and efficiency(effluent concentration)of BOD5, CODMn, CODCr, T-N and T-P in the treated water was 96.1%, 87.7%, 90.6%, 86.6% and 84.5%, respectively. 본 연구는 생물학적 처리공정의 하나인 SBR을 이용하여, 양돈폐수중의 유기물과 질소, 인의 동시제거를 목적으로 적정의 수리학적 체류시간(HRT)과 반응기간 중 교반/폭기 시간비(M/A) 및 적정의 교반/폭기 시간비에서의 외부탄소원의 주입기간(Injection Time)에 따른 변화에 따른 실험 결과로부터 다음과 같은 결론을 얻었다. (1) NH4+-N의 제거효율은 M/A가 0.0/22.0일 때(Run 1) 가장 효율이 좋았으며, 외부탄소원을 주입했을 경우 탈질균의 증식으로 인해서 질산화가 잘 이루어지지 않기 때문에 주입시간이 길어질수록 증가하였다. T-N의 제거효율은 M/A가 증가할수록, 외부탄소원 주입시간이 길어질수록 증가하였다.(2) T-P의 제거효율은 운전조건에 따라 큰 차이를 보이고 있으며, M/A가 증가할수록 제거효율은 증가하였으며, 외부탄소원의 주입기간을 두고 보았을때, 주입기간을 짧게 할 경우 탈질균의 증식으로 인해서 탈질이 더 효율적으로 이루어지기 때문에 그 제거효율은 증가하였다.(3) 총 반응시간 22시간 중 M/A 16.5/5.5, 무산소 기간의 16.5시간 중 15시간동안 외부탄소원을 주입했을 경우(Run 4-1)의 운전조건에서 유기물 및 질소 제거에 가장 효율적이었으며, 인의 경우 무산소기간의 16.5시간중 3시간 동안 주입한 경우(Run 4-2)인 경우가 가장 효율적이었다. 각각의 효율을 살펴보면, CODCr, CODMn 그리고 BOD5인 경우, 각각 90.6%, 87.7% 그리고 96.1%이고, T-N의 경우 86.6%, T-P인 경우는 84.5%로 나타났다.

Background : Platycodon grandiflorum has been used as famous medicinal vegetable and traditional medicine in Korea. Platycodon grandiflorum is used more for vegetable than it is used as a medicine. Proper storage conditons are required for distribution of Platycodon grandiflorum as vegetables. The purpose of this study was to find the appropriate storage temperature. Methods and Results : 2-years old Platycodon grandiflorum cultivated in Herbal Crop Research, RDA Eumseong was used. They were packed with plastic container box of 45 × 70 × 30 ㎝ and then stored at –2℃, 2℃, 5℃, 25℃, humidity 80 - 82%. During the storage, hardness, L a b values, weight loss, decay rate were measured every 30 days as quality indices. During the storage period, L value decreased but a and b values increased and same pattern was observed at all storage temperatures. Hardness decreased and same pattern was also observed at all storage temperature. Under constant humidity conditions, weight loss was larger at higher temperature. The higher the temperature, the larger the deviation at weight loss. There were little decay but 25℃ temperature stored showed that dacay rate was higher with time over. Conclusion : The favorable temperature for storage is –2℃ - 2℃ while maintaining constant humidity.

The dissolution and reaction of ozone in sea water with bromide has been tested. In order to obtain the optimal amount of injected ozone which is needed for the oxidation of ammonia in sea water, dissolved ozone concentration and temperature have changed into three conditions, which are 1, 1.5. 2.5 mg/L and 15, 20, 23℃ respectively. In this study, Ammonium nitrogen has been injected with different concentration of 0.5. 1, 1.5 and 2mg/L at each Run and at Run 3 which has high dissolved ozone concentration. 5 and 10mg/L of NH_(4)-N has been added. pH has decreased rapidly in ten minutes in accordance with denitrification of ammonium nitrogen. With increasing ammonium nitrogen concentration, it has decreased significantly within five minutes and then slowly. In the rate of 1-2.5mg/L of injected ozone concentration, the removal efficiency of ammonium nitrogen has increased clearly with increasing ozone concentration. In the course of denitrification, the variation of nitrate nitrogen and nitrite nitrogen has scarcely been measured. This is considered that ammonium nitrogen has been denitrified by a complicated mechanism rather than by a simple removal through its oxidation. and has been emitted into the air as nitrogen gas in a short time.
