| Abstract |
More than 85% of cow farms are raising below 10 heads, while more than 58% of pig farms below 100 heads. As the small-scale livestock farms are widely scattered in Korea, the load of pollution generated from these small farms becomes over the control. This investigation was conducted to suggest the best management for the livestock wastewater. Totally 104 livestock farms, including 63 for pig and 41 for cow, and the livestock wastewater treatment facilities were surveyed for 5 provinces and 6 cities (or districts) in the regions of Seoul metropolitan, water quality protection area, seashores and the mountain side. In order to reduce the pollution load from the livestock farm and to improve the management of treatment facilities, the solid-liquid separation facilities should be employed to the new farms and the farms with increasing livestock. For the small-scale livestock farms, it is rather reasonable to have the simple storage type of facility. In the other hand, the political support should be made for the farm cooperations units to produce and store the recycled fertilizer for good-time sale. |
