Abstract: Leachate from garbage-dumped landfill brings serious contamination in downstream waters. Micro-bubble aeration was conducted in order to experimentally examine its purification performance. Three types of gases, (i) natural air, (ii) oxygen and (iii) ozone, were used for the aeration. Performance of water purification was discussed based on water quality measurements in the water tank experiments. The laboratory data showed that the most significant oxidation occurred in the oxygen aeration tank in which nitrification was accelerated most efficiently among the three gasses. Both the ozone and the atmospheric-air tanks show lower water purification performance. Manganese was most tremendously reduced through oxidation of ionic manganese by the oxygen aeration as well.
