As a basic research on applying the microbial strains which had been isolated and proved to remove heavy metals, such as Pb, Cd, Zn, and Cu in This laboratory to actual wastewater treatment, optimum condition of the treatment system with addition of single or multiple species of pollutants and microorganisms were investigated at small scale. Concentration of the bacterial inoculum was 3000㎎/L and 1500㎎/L of MLSS for treatment with single and multiple species, respectively. Removal rates of heavy metals were expressed at HRT`s (Hydraulic Retention Time) of 12, 24, and 48 hr. Removal rates of Pb, Cd, Zn, and Cu after 12 days at HRT of 24hr with addition of single and multiple species were 93%, 90%, 80%, and 39%, and 75%, 90%, 74%, and 48%, respectively. Judging from these results, treatment capability of the isolated strains is excellent. Hence, the microorganisms are expected to be applicable to actual wastewater treatment.

사용종료매립지에서 시간경과에 따른 침출수의 특성

허종수,성낙창,김형석,김은호 한국환경농학회 1997 한국환경농학회지 Vol.16 No.2

부산광역시의 대표적인 사용종료 쓰레기매립지인 H. 매립지, S. 매립지와 E. 매립지의 시간에 따른 침출수의 특성을 조사한 결과를 요약하면 다음과 같다. 1. 최근에 사용종료된 E. 매립지의 경우 H. 와 S. 매립지에 비하여 pH 변화특성이 아주 급격하게 증가하는 추세를 나타내고 있는데, 이는 혐기성 분해작용으로 인하여 생성된 NH₃ 용해와 NO₃의 탈질과정으로 pH가 상승하는 것으로 추정된다. 2. BOD와 COD_(Cr)의 변화는 아주 크며, E.와 S. 매립지의 경우 매립초기에는 비슷한 농도로 높은 반면에 H. 매립지의 초기농도는 낮게 보이고 있는데, 이는 매립당시 쓰레기의 성상이 다른 매립지에 비하여 유기성 물질의 농도가 낮기 때문으로 판단된다. 3. 가연성 물질 중 음식물류가 차지하는 비율이 높은 E. 매립지의 경우 H.와 S. 매립지에 비하여 초기부터 전반적으로 고농도의 SS를 유지하고 있으며, 상당히 심하게 농도가 변화하는 것을 알 수 있다. 4. 매립시간이 경과할수록 T-N의 농도가 증가하는 현상을 보이지만 T-P는 비슷한 양상을 나타내고 있으며 T-N성분은 NH₃-N가 대부분을 차지하고 있고 질산성 질소는 거의 미량으로 존재하는 것으로 나타났다. 5. 침출수 중 대표적인 중금속은 대부분이 한계농도 보다 낮은 농도를 보이며 생물학적 처리시 미생물에 그다지 영향을 미치지 않을 것으로 사료된다. In this study, we can be obtained the following conclusions about the characteristics of leachate with passed time in the expired landfill. Compared with the expired landfilling H. and S., pH shows a tendency to increase in E., because NH₃ is created by anaerobic degradation and dissolved in leachate. The initial BOD and COD of E. and S. are high in similar concentration but H. is low, Since the organics of waste in H. are lower than in E. and S. during landfilling. SS of E. in concentration is increased and very altered, because food of combustible in E. is higher than it in H. and S.. According to passed time, T-N is high in concentration but T-P shows a similar tendency. Heavy metals of leachate is lower than threshold concentrations. If leachate is treated biologically, microbes are not inibitory.

Of the copper-tolerant 215 bacterial strains isolated from polluted river water, wastewater and activated sludges of wastewater treatment plants, or wastewater and soils of the copper mine aera in Gyeongnam province a strain, which showed considerably higher growth rate in the agar plate containing 2000ppm of copper than any other strains, was identified as a Pseudomonas stutzeri or its similar strain when analyzed by taxonomical charicteristics. Optimum pH and temperature for the growth of the P. stutzeri were 7.0 and 30℃ respectively. This strain was resistant to antibiotics, such as ampicillin and tetracycline, and heavy metals, such as lead and chromium. This strain utilized phenol benzen or toluene as a sole carbon source. The rate of copper accumulation in P. stutzeri cell was enhanced at low concentration of Cu in the growth media. The maximum copper absorption by this strain grown in 10ppm of Cu at 3 days after culture was 49%, but in 50ppm and 100ppm of Cu was 38% and 32%, respectively. The optimal temprature and pH for the effective intracellular accumulation of copper were 30℃ and initial pH 8.0 under shaking culture.

허종수,김원주,민병욱,신수범 한국농화학회 2001 Applied Biological Chemistry (Appl Biol Chem) Vol.44 No.4

Leather (skin & hide) is a body organ, comprising 3 to 5% of the animals weight. The cross-section of a leather is composed of two major divisions: the epidermis or grain layer and the corium or split layer. The leather is naturally covered with bacteria and fungi, because it is a particularly rich source of a wide variety of microorganisms. Stains or coatings of different colours occur in patches or over large areas, depending on the type of mould spore infestation. We examined the antibiotic effect of leather after washing. Upon applying equal fungicide, antibiotic effects increased as follows: grain layer$gt;middle layer$gt;flesh layer. Antibiotic effect decreased with increasing frequency of washing. Decrease in antibiotic effect was lower in OITZ fungicide than in TCMTB and CMK fungicides. Sulfated fatliquor showed higher antibiotic effect than phosphated fatliquor.

남강의 수질예측을 위한 QUAL2E 모델 적용

허종수,박태주,최형섭 한국환경농학회 1995 한국환경농학회지 Vol.14 No.1

하천 수질관리 모델인 QUAL2E를 남강에 적용한 결과는 다음과 같다. 1. 모델변수의 민감도 분석 결과는 BOD, DO의 경우 BOD decay rate constant, 영양염류인 경우 Org-N oxidation rate constant, NH₃-N oxidation rate constant, Org-P decay rate constant가 각 수질인자에 중요한 변수로 작용하였다. 2. 모델보정 결과를 보면 실측치와 예측치의 상관성은 DO, BOD의 경우 r=0.93, 0.94로 높은 상관성을 보였으며 영양염류인 경우는 질산성 질소가 r=0.61이었으나, 그 외는 r=0.90 이상으로 나타났다. 3. 모델검증 결과는 보정시보다 상관성이 떨어졌으나 DO, NO₃-N 경우 r=o.68, 0.45로 낮고 그 외는 r=0.75이상으로 높은 편으로 나타났다. 4. 유량과 부하량의 변화에 대하여 하류 40.5 Km 이후의 BOD 농도변화는 적었으나, 하수종말처리장 건설이후 유량과 부하량을 변화시켜 수질농도를 예측한 결과 하류 40.5 Km 이후는 함안천의 영향을 받을 것으로 예측되었다. This research was conducted to apply the QUAL2E model to be adopted to the Nam river under current water quality conditions. The survey area of total 60 Km was divided into five reaches. Each reach was then subdivided into the uniform computational elements of 1.5 Km. Based on the stream characteristics, nine sampling stations consisting of six at main streams and three at tributaries were selected. The field data were obtained from the selected stations twice during October of 1991 and May of 1992, which represented the cold weather and low flow, also the warm weather and low flow conditions, respectively. As the results of sensitivity analysis of the model, the important parameters were the rates of BOD decay, Org-N oxidation, NH₃-N oxidation, Org-P decay. The calibrated and verified results by QUAL2E model were correlation coefficient of 0.45∼0.94. The results displayed a good agreement between the variables of the field measurements and the model simulations, indicating a potential use of the QUAL2E model for the water quality assessment in the Nam River.
