한양수,오상재,김세희,오세화,배석수 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0

Highly porous cylindrical-type gas filter media containing copper-manganese oxide catalyst was prepared by roller-dice extrusion method using Cu:MnO_x/SiO₂ composite precursor, which was obtained by a redox precipitation and subsequent hydrolysis of alkali silicate solution. In a typical preparation nano-sized Cu:MnO_x particle was prepared at first by a redox reaction between Mn⁷⁺ and Cu²⁺/Mn²⁺ aqueous solution, followed by a acid-catalyzed hydrolysis of sodium silicate solution in the presence of CuMnO_x particle, leading to Cu:MnO_x/SiO₂ composite materials with very high specific surface area (S_BET) of > 650 ㎡/g and large pore volume of ~ 0.6 mL/g with the pore dimension of 3~5 nm. The physical properties such as apparent packing density, pellet hardness, and porous characters (surface area, pore volume, and pore size) along with the gas removal performance (CO, NO₂, NH₃, and CH₃CHO) were investigated in detail.

A wet-chemical route was utilized to obtain nanosized crystalline goethite ($\alpha$-FeOOH) particle, which was known as an oxidation catalyst in reducing carbon monoxide (CO) and dioxine during incineration. A cost-effective $FeSO_4{\cdot}7H_2O$ was used as starting raw material and a successive process of hydrolysis-oxidation was utilized as synthetic method. The effects of the initial $Fe^{2+}$ concentration, hydrolysis time and oxidation period on the crystalline phase and particle characteristics were systematically investigated by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and BET analyses. It was found that the spindle-shaped crystalline $\alpha$-FeOOH particle with the width of 70 nm and the length of 200 nm could be obtained successfully when the initial concentration of 1.5 M, hydrolysis time of 4h, and oxidation period of 10 h, respectively. In addition, it was observed that the spindle-shaped $\alpha$-FeOOH particle consisted of nano-sized primary crystallites of $30\~50\;nm$, which were de-agglomerated into individual particle and successively re­agglomerated into spherical or irregular-shaped agglomerates beyond certain periods in the hydrolysis and oxidation process.

The growth of population and industrialization has been increasing the discharge of wastewater and requiring more intensive eater treatment processes. This study was carried out to determine the optimal design conditions of a sewage treatmentplant in the small city of Keumsan. Also, we set out to find the operation guide data pertaining to the activated sludge process required by a city of this size. The biological reactors were operated with hydraulic retention times (HRT) of 8hrs, 6hrs and 4hrs respectively, at the temperature of 20±1℃, using a mixture of raw wastewater. From the results of the experiments, we found that the removal efficiency increased as the F/M ratio decreased. From this confusion we found that we could get the TBOD removal efficiency above 90% if the F/M ratio was less than 0.2Kg BOD/Kg MLSS-day. For the reaction conditions with a hydraulic retention time of 8hrs, the removal efficiencies of TBOD, SBOD, TKN and T-P were 92.4%, 92%, 87%, 67% and 49.3% respectively.

대청다목적댐의 수질 모델링

류병로,이재경,한양수 大田産業大學校 1993 한밭대학교 논문집 Vol.10 No.1

This study was conducted to develop the water quality simulation model(RBOX) to describe the temporal and spatial variation of the two dimensional water quality concentrations in Taechung reservoir. Modeling efforts are divided into two parts; 2-dimensional water quality modeling by RBOX model, and water quality modeling included stream water quality (QUAL2E-H) and reservoir water quality (WQRRSR) for the Taechung dam. The RBOX modeling system was designed to provide the generality and flexibility necessary for analyzing a verity of water quality problems in a diverse set of water bodies. An algorithm has been composed of a hydrodynamic module which solves the equations of motion and continuity, a pollutant dispersion module which solves the dispersion-advection equation. RBOX can simulation up to 10 water quality constituents; i.e., daily output of Dissolved oxygen, pH, Temperature, Algae as chlorophyll-a. Ammonia as nitrogen. Nitrate as nitrogen. Dissolved orthophosphate as phosphorus, Alkalinity, Biochemical oxygen demand and Suspended solid. Actual simulation were applied to the whole region of the Taechung reservoir considered the influx of the three tributury inflows (okchun chun, Taejon intake tower and Chungju intake tower). The results of simulation have shown the two dimensional water quality concentration profiles. Calibration of the calculated flow fields and water quality parameters to be accomplished since no available field measurement data were performed in Taechung reservoir. After calibration and verification of the model, water quality simulations were also performed for 1996, 2001 and 2006, under assumption of neither additional treatment nor interceptor sewers with QUAL2E-H model. And also water quality were predicted for the lake water with WQRRSR and RBOX model. Considering the polutants removal plan of the EPA, water quality simulations were also performed for 1996, 2001 and 2006. Efforts have also been made to compare the predicted water quality for each removal plan. As a further study, RBOX can be very helpful tool as optimum water quality management in Taechung mulipurpose reservoir, say, database link system.
