To deal with t]?e rapid deterioration of the water environment that has occurred in recent years at dam reservoirs and other water resource areas located close to farming and rural communities in Korea, methods of treating domestic wastewater and live-stock wastewater are being improved. The number of small scale treatment plants processing domestic and live-stock wastewater in these regions is, therefore, forecast to increase. This means that to deal with the sludge that will be produced as a by-product of this wastewater treatment, there is an urgent need to develop small scale treatment methods rather than the large scale treatment methods provided in the past. This research study, one undertaken in light of the above circumstances, was a study of the application of the thermophilic oxic process method, one that is based on the familiar principle of the composting reaction and permits the total decomposition of organic material, to the treatment of sludge and high concentration organic wastewater produced by live-stock raising. The results have shown that because these organic materials have high water content, a heat source such as waste food oil must be added to them, and that according to the quantity added, there may be insufficient nitrogen for the reaction. It is, therefore, important to provide the optimum water content and C/N ratio.
