In South Korea, the standard facility capacity for bioenergy facilities is set at 100 tons per day based on livestock manure amount by bioenergy-related laws. To achieve the government's goals for the energy recovery from livestock manure, there is a need to expand and distribute centralized facilities with a capacity of 100 tons of livestock manure per day. The location and scale of these centralized facilities are influenced by the geographical location and livestock breeding scale of nearby livestock farms. The size of most domestic pig farms is small, thus it is necessary to analyze the distribution and density of medium-sized or larger livestock farms capable of supplying manure to centralized facilities. In this study, kernel density analysis and spatial density analysis were conducted to select suitable regions for centralized biogas facilities for pig manure for Gyeonggi-do. As a result of analyzing the Gyeonggi-do region as a case study, four regions in southern Gyeonggi-do and one region in northern Gyeonggi-do were estimated to be suitable regions. Although it is necessary to confirm specific suitable regions through a feasibility assessment of regions estimated to be suitable regions, it is believed that selecting candidate regions first and conducting a feasibility study through kernel density analysis will save time and help in rational decision-making.

The slurry composting and bio-filtration (SCB) liquid manure has some obvious advantages including a good source of N, P and K, local availability, effective microorganism and the ability to improve soil properties. This study was conducted to evaluate the influence on the changes of soil chemical properties and yield of red pepper by fertigation cultivation with SCB application for 2 years. ). The fertigation cultivation which was installed the surface drip irrigation system was splitted 10 times as 2.5 Mg 10a -1 nutritional solution included with chemical fertilizer and SCB every 10 days during the cultivation. The height and width of pepper plant were 7.0% and 5.8% higher in SCB 2.0N treatment than that in control. The yield of red pepper increased with the increasing of SCB application rates from SCB 0.5N to 2.0N. The yield of SCB 1.0N was much better 10% in average than that of control, and there was significant differences among all treatments. pH of control soil after final harvest decreased to 6.1, however pH of SCB treated soils increased from 6.7 to 7.1 depending on SCB application rates. The Exch.-K contents of SCB treated soils were increased 13.7 to 56.9% after final harvest compared with control by 0.51 cmol c kg -1. Accordingly, these results showed that SCB 1.0N application rate as a recommended nitrogen level based on soil testing can be used as an alternative nitrogen management as well as plant nutrition for red pepper cultivation.

Nightsoil and piggery wastes generally present high strength organics and nitrogen. This study evaluated the nitrogen removal characteristics with the existing and modified nightsoil and piggery waste treatment plants. The existing conventional plants showed 20 to 40% nitrogen removal, but the modification with SBR or MLE process could remove effectively both nitrogen and organics with the minimum COD/TN and alkalinity/TN ratios of 6 and 3.6, respectively. Nitrite nitrification and denitrification rates obtainable at higher nitrogen loads were faster than the rates of nitrate nitrification and denitrification resulting in less reactor volume requirement. However, the higher nitrogen loads increased the organic loads resulting in the reactor temperature inhibiting nitrification. Thus, a combined treatment with anaerobic digestion with the adjustment of influent bypass rates was proposed to reduce the reactor temperature and the external carbon requirement. The biological treatment could discharge about 1,100 mg/L soluble COD and 50 mg/L soluble nitrogen, respectively.
