Abstract

Down pushed flow anaerobic reactor (DPAR) was adopted in the paper to reveal the yielding gas process by taking swine manure as the material under different volume organic loading (3.11, 4.44, 5.78 gTS.L-1.d-1) and to detect the optimal volume organic loading for semi-dry fermentation of swine manure. The results indicate that: The higher the organic loading, the higher volume gas productivity, while the lower biogas production velocity of the material will be. The change of organic loading has few aggregate impacts on ammonia nitrogen. Besides, due to long duration of acclimation, the tolerance of microorganism will be significantly enhanced. The preferred organic loading for semidry fermentation of swine manure with DPAR is 4.44gTS.(L.d).
