A fixed-film biological reactor(FFBR) packed with SAC(Synthetic Activated Ceramic) media was tested to investigate the removal efficiency of both organic matter and ammonia of raw sewage and final effluent of J municipal wastewater treatment plant in Pusan. The influent to the wastewater treatment plant of the city of Pusan consists of typical municipal wastewater and the discharges of industrial works and sanitary landfill leachate. Experiments were performed to evaluate the removal efficiencies of chemical oxygen demand(COD_(Cr)) and ammonia in two lab-scale FFBR by increasing COD_(Cr), loading rate from 0.85㎏/㎥/day to 1.24㎏/㎥/day and NH₄^+-N loading rate from 0.24㎏/㎥/day to 0.48㎏/㎥/day in case that raw sewage were used as substrate. In case of final effluent as substrate, the FFBR demonstrated of achieving 28.3∼33.4% removal efficiencies of COD_(Cr) at the COD_(Cr) loading rates of 0.28∼0.55㎏/㎥/day and 67.0∼85.3% removal efficiencies of NH₄^+-N at the NH₄^+-N loading rates of 0.13∼0.38㎏/㎥/day. The results of the research showed that a fixed-film biological reactor(FFBR) packed with SAC media could be applicable for treatment of raw sewage and final effluent since the process is, compared to the conventional activated sludge process, more effective at the sewage including high NH₄^+-N loading rates.

Synthetic activated ceramic(SAC) adsorption isotherms were determined experimentally for the raw sewage and final effluent of JANGLIM sewage treatment plant. SAC media used in this study is the media made under high temperature, which has many pores on the surface. The well-known Freundlich equation developed for this work, was used to describe single solute equilibria. As expected, the Freundlich equation was able to more accurately describe single solute isotherms which deviated from log-log linearity. It showed that the adsorbed COD mass per adsorbent mass in the adsorption equilibrium was larger in raw sewage(1.40mg/g) than in effluent(0.28mg/g), when the adsorbent mass was 50g. SEM(Scanning Electron Micrograph) of SAC media indicated that a large of biomass were attached in the surface and pores of the SAC media, after 90 days of operation.

This study was conducted to investigate the mercurous content of surplus amalgam and washing solution generated from dental treatment. 300 surplus amalgam and washing solution samples were collected from twenty dental clinics in Taegu. The average mercurous amounts of washing solution and surplus amalgam samples were shown as 0.081 mg/day and 16.81 mg/day, respectively. The Shinchon and Keumho stream were shown as 0.027 mg/L and 1.164 mg/L of mercurous concentration, which would be linked to the 86 dental clinics and industrial complex in the survey area. Based on the annual reports of the medical insurance union, the annual amount of discharged mercury in dental clinics to the sewage was estimated to 9,725.59 g in 1990, 10,223.69 g in 1991, 11,585.12 g in 1992 and 12,188.78 g in 1993. It was founded that the amount of discharged mercury from dental clinics was increased every year and was caused by washing solution and surplus amalgam from dental clinics.
