초록

The amount of food waste is generated every year in Korea. Despite food waste contain a large amount of valuable organic resources, The rate of recycling is low because of high moisture contents and sodium. It proposed a solution to the problem is the Hydrothermal carbonization (HTC) technology. The Bio-char is produced by HTC allows to increase the recycling uses. The agents of heavy metal adsorption are mainly used with lime and activated carbon. However, these have difficulties such as low economical feasibility and solubility. This study focused on the application of the adsorbent. It is expected to have advantages in heavy metal waste water like Acid Mine Drainage (AMD) or industrial effluent. In this study, the adsorption capacity of bio-char was measured with the conditions of the time and the amount of bio-char inputs to remove in the artificial AMD. Artificial waste water 10 ppm and 100 ppm was prepared using Cu, Pb, Cd, As, and analyzed a batch-test to find the optimum condition. The experimental results showed The optimal blending ratios with activated bio-char and contaminated water were 1 : 20 for high concentration (100 ppm), 1 : 100 for low concentration (10 ppm). As the results, the absorption efficiency of the heavy metals, shows more than 99% except for arsenic.
