Operating conditions of aerobic fixed biofilm process for the removal of nonbiodegradable organics and color from a landfill leachate were developed. Prior to the biological process, Fenton oxidation was carried out as a preliminary step. The influent to the biological process was diluted with methanol, and the residual organics and color in the effluent were treated again by second stage Fenton oxidation. The average CODcr of the leachate samples was 2,000mg/L and oxidation carried out prior to the biological process showed a 68.1% COD removal and the color change from dark brown to pale yellow. The result of the aerobic fixed biofilm process in dicated that the optimal dilution ratio was approximately 50% and the additional COD removal was 68.2%. Effects of organic loading were also examined, and the appropriate influent organic loading(as COD) to obtain the effluent COD below 300mg/L was found to be less than 8g/㎡?day. In a secondary Fenton process using the effluent from the biological process, the residual COD was as low as 148mg.L and the color was changed from pale yellow to colorless.

From 2014 to 2016, water quality of Youngrang Lake was surveyed, according to the location and depth. Following observations were recorded. Distribution of dissolved oxygen in the water depth was investigated at the middle section and the downstream 1st, 3rd, 5th, when investigating the bottom lm interval anoxic layer. The organic matter and nutrient concentration distribution was COD upstream 2.8 mg/L, middle section 4.2 mg/L downstream 4.1 mg/L, which was more than two times higher in the bottom layer. The TP concentrations showed a similar trend as the COD, being 0.047 mg/L at upstream, 0.051 mg/L in the middle, and 0.059 mg/L downstream. Difference in salinity was observed at every survey period; the lowest salinity recorded 28.5% during the second survey, and highest was 32.1% in the fourth survey. Korean trophic state index (TSIko) showed eutrophic conditions in the middle section and downstream, whereas mesotrophic state was maintained elsewhere during the entire period. In order to evaluate the cause of water pollution of the Youngrang lake, regression analysis determined the relationship between salinity and DO, COD, TN,TP, Chl-a; the results indicated R2 from 0.63 to 0.95. Youngrang lake water quality had a close relationship with salinity due to inflow of seawater. As a result,in order to improve the quality of Youngrang lake, efficient incorporation of the amount of water through the seawater influent is considered the key.

Objectives: The purpose of this study is to evaluate the characteristics of leachate discharged from livestock burial sites in Gangwondo resulting from foot-and-mouth disease by monitoring the water quality at the survey tube-wells installed near livestock burial sites in order to investigate the effect of the leachate on the quality of nearby underground water and suggest a water pollution level in accordance with water quality evaluation criteria. Methods: To minimize the secondary environmental pollution damage caused by leachate at burial sites of livestock killed by foot-and-mouth disease, this study analyzed the leachate directly discharged from burial sites and installed survey tube-wells within 300 meters of livestock burial sites and investigated water quality as a means to ascertain the environmental effect of the leachate from the burial sites. In accordance with environmental management guidelines on livestock burial sites, this research investigated the water quality in the survey tube-wells in fifty five burial sites in Gangwondo. The elements investigated were $NH_3$-N, $Cl^-$, $NO_3$-N, conductivity, and E. coli. Water quality was monitored from 2011 to 2013. Results: The water quality from the drain pipe at the location of leachate from livestock burial sites showed BOD 37,209 mg/L, COD 8,829 mg/L, $NH_3$-N 3,633 mg/L, and $Cl^-$ 580 mg/L. According to the monitoring results of water quality ($Cl^-$, $NH_3$-N, conductivity) at the survey tube-wells, there was suspicion that 13 out of 55 burial sites discharged leachate, five sites discharged highly concentrated leachate (13%): one in Gangneung, one in Wonju, and three in Cheorwon. Conclusion: It was judged that out of thirteen observation wells which showed a possibility of discharged leachate, three survey tube-wells have established the discharge effect of leachate at burial sites up to recently. Therefore, it is judged that it is necessary to continue monitoring them and devise additional measures.
