摘要: This article provides introductory explanations on sewage sludge technologies. These technologies are divided into three categories, namely characterization and ecology; municipal wastewater treatment using activated processes; processing. Commonly accepted compositions, indices, classification criteria, ecology summarized in the first part, which forms a foundation for further developments. A study processes is then carried out with emphasis biological nutrient removal accomplished secondary stage. Biological reaction mechanisms of organic carbon, nitrogen, phosphorous compounds, together modeling control issues encountered processes, addressed. Finally, various processing techniques including thickening floatation, stabilization, conditioning, dewatering, drying preceding final disposal ecological impacts analyzed.
