BzCuO2 의 생성 자유에너지를 이중 이온교환된 Ba2+-$\beta$/$\beta$"-AI2O3를 전해질로 사용하여 다음과 같은 생성셀로부터 측정하였다. Au(po2=10-3)/Au+BaCuO2+CuO// Ba2+-$\beta$/$\beta$"-Au이 갈바닉셀에서 BzCuO2 의 임의의 생성식과 생성자유에너지는 다음과 같다. BaO+CuO=BaCuO2 $\Delta$fGo/kJ.mol-1=-77.3-3.3x10-3T/K.3x10-3T/K.
EMF 방법에 의한 $Y_2Cu_2O_5$의 생성자유에너지 측정
김수권 한국세라믹학회 1995 한국세라믹학회지 Vol.32 No.9
The formation free energy of Y2Cu2O5 was measured by the partial ion exchanged (Cu2+, Na+)-$\beta$/$\beta$"-Al2O3 as solid state electrolyte. The formation cell was built as follows: Pt(O2)/Y2Cu2O5+Y2O3//(Cu2+, Na+)-$\beta$/$\beta$"-Al2O3//CuO/(O2)Pt The virtual formation formation formula, and the calculated formation free energy of Y2Cu2O5 as a function of temperature are as follows: 2CuO+Y2O3=Y2Cu2O5 ΔfG0/kJ.mol-1=13.19-16.25*10-3T/K.5*10-3T/K.

In order to treat wastewater from a factory manufactured electrical accessories. sludge returned CMAS reactors of MLSS 2000mg/l were operated with various HRTs of 5.40hrs. 7. 89hrs, 15.6hrs, and 30.8hrs at a temperature of 20℃. The results showed that it was difficult to get 80% of TCOD removal even with longest HRT(30.80hrs) while more than 80% removal of TBOD was achieved with 7.89hrs of HRT. To remove 80% of BOD and 70% of COD, F 1M ratio was reqiured to maintain 0.17kg BOD/kg MLSS. day, even in this case, the removal rates between TBOD and SBOD were significantly different. The calculated substrate removal rate(Km) was 1.26/hr, and the calculated cell conversion rate of organic matters(S/TE) was 0.26 on the base of BOD. Estimated cell yield coefficient (Y), cell synthesis coefficient(ke). and endogenous respiration coefficient(ke) were 0.242, 0.31/hr, and 0.02/hr. respectively. The effluent concentration of TBOD. SBOD, MLVSS in aeration reactor, and oxygen uptake rate(dO/dt) were ranged 9.1∼25.4mg/l. 4.9∼11.9mg/l, 1,375∼1,983mg/l. and 5.4∼30.19mg O_(2)/·hr, respectively. These observed values are agreed relatively well with calculated values. The sludge production rates per HRT were ranged 0.443∼1.28g SS/day, and the sludge production rate per BOD removal were ranged 1.635∼2.717g SS/g BOD_(rem). These values are close to the calculated ones. The best sludge dewatering rate was achieved with 15.60hrs of HRT and its specific resistance(α) was 2.68×10^(11)sec/g.

When influent substrate was nonbiodegradable phenol, it was treated by Anoxic-Anaerobic-Aerobic system with single return sludge. The operating condition was completely mixed batch reactor with recycle. This system was operated to scrutinize time tracks of COD, NH_(3)-N, Ortho-P, DO, and ORP. Oxidation-Reduction Potiontial(ORP) measurements were made in conjunction with monitoring of other process variables in biological nutrient removal system to determine the suitability of using this parameter to monitor and characterize conditions in un-aerated bio-reactor. Results obtained indicated that ORP could provide a very meaningful indication of process and ORP was found to correlate with observed phosphorus release in anaerobic environment.

본 실험은 3개의 F/M 비 0.36, 0.2, 0.1 mg COD/daymg MLSS로 실험실 규모의 활성슬러지법에 의해 전선공장폐수를 처리사고, 유입수와 유출수의 Daphnia magna에 대한 급성독성을 연구하였다. Daphnia Magna를 이용하여 실험실 bioassay를 수행한 결과는 다음과 같다. 1) 유입수의 24hr, 48hr-LC50은 각각 17.33%, 11.73%이었다. 2) F/M 비 0.36, 0.20, 0.10 mg COD/d This study was to determine the static acute toxicity on Daphnia magna for the Electric cable Factory Wastewater. Activated sludge process was used to treat the wastewater with three different F/M ratios, 0.36, 0.2, 0.1 mg COD/day.mg MLSS. The results of

Leaching characteristics and adsorption ability of Fe and Mn in the paddy soil were studied with synthetic acid rain. 1. Leaching quantity of Fe from the paddy soil by acid rain was 8 times as much as by neutral rain, and 6 times for Mn. 2. Leaching quantity was changed with heat treatment methods of sample soil (ignition or air drying), with kind of meta](Fe or Mn) and with acidity of soil (acid or netural). 3. The adsorption ability of Fe on the paddy soil was twice as much as, that of Mn. 4. Langmuir isotherm equation was c/q=20C+10 for Fe(air drying paddy soil) and c/q=160 C - 610 for Mn(ignation paddy soil). 5. Contineous column experiment showed that the adsorption ability of Mn was above 100, and for Fe, it was changed with kinds of sample soil and pouring methods.
