Oxygen Diffusion and Microbial Activity in the Composting of Dehydrated Sewage Sludge Cakes
スポンサーリンク
概要
- 論文の詳細を見る
The effective diffusivity for oxygen within sewage sludge cakes was measured, and in turn used for the study of microbial activity in the sludge cake composting. The diffusivity was found to be proportional to the one and a half power of the sludge cake porosity. Composting experiments were done using two types of sludge cakes, 5 mesh sieved and pelletized. It was found that the microbial activity in the inner core region of the pelletized sludge cake was significantly less than that in the outer region, even though the rate of oxygen diffusion was fast enough to support the microorganisms' activities. It appears, therefore, that microorganisms acting to degrade organic matter grow primarily on the macroscopic interface between solids and air.
