Abstract

In this study, the introduction of solid-liquid separation process in wet anaerobic digestion treatment system, which can treat the semi-solid manure, was investigated for composting the solid fraction without adding any secondary material and increasing the concentration of organic matter in the liquid fraction The recovery rate of sawdust was over 96% by screw press with wedge wire screen (slot size, 0.8mm). The same degrees of the fermentation temperature and the decomposition rate of organic matter were observed in both of composting of the solid fraction and the sawdust-added material. The concentration of organic matter in the liquid fraction was increased by the reuse o f the liquid fraction to slurry the manure.
