This study was performed to evaluate the removal effects of nutritive salts and organic pollutants in experimental aeration reactor for treatment of piggery slurry. In this study, three types of reactors were manufactured and operated. The fibrous media was equipped in one of three reactors. Another reactor was equipped with the siliceous media and the other reactor used as a control was equipped with typical aeration system only. Treatment efficacy of three types of reactors were evaluated according to the pollutants removal rate of the piggery slurry. The results obtained in this study are as follows : 1) In the reactor containing fibrous media, the removal efficiency of BOD, T-N and T-P was 11%, 13.9% and 21.2%, respectively. 2) In the reactor containing siliceous media, the removal efficiency of BOD, T-N and T-P was 6.9%, 25.3% and 47.8%, respectively. 3) In the reactor not containing media, the removal efficiency of BOD. T-N and T-P was 6.1%, 8.1.% and 23.6%, respectively. 4) Sludge accumulation in the reactor equipped with filamentous media was lower than that of other experimental reactors.

Recently, anaerobic methane production of agricultural waste biomass has received increasing attention. Until now domestic BMP (Biochemical methane potential) studies concerned with agricultural waste biomass have concentrated on the several waste biomass such as livestock manure, food waste, and sewage sludge from WWTP (Waste water treatment plant). Especially, the lack of standardization study of BMP assay method has caused the confused comprehension and interpretation in the comparison of BMP results from various researchers. Germany and USA had established the standard methods, VDI 4630 and ASTM E2170-01, for the analysis of BMP and anaerobic organic degradation, respectively. In this review, BMP was defined in the aspect of organic material represented as COD (Chemical oxygen demand) and VS (Volatile solid), and the influence of several parameters on the methane potential of the feedstock was presented. In the investigation of domestic BMP case studies, BMP results of 18 biomass species generating from agriculture and agro-industry were presented. And BMP results of crop species reported from foreign case studies were presented according to the classification system of crops such as food crop, vegetables, oil seed and specialty crop, orchards, and fodder and energy crop. This review emphasizes the urgent need for characterizing the innumerable kind of biomass by their capability on methane production.
