本研究涉及从城市污水处理厂的阿德拉尔市（阿尔及利亚西南部）发出的污泥的处理和增值。所考虑的污泥是一种复杂的物质混合物，基本上是有机物质，比例为54%。观察到粗底物的急性生物活性（1.67 × 106个细菌/1 ml）。将总固体含量为16 g/l（TS）的稀释污泥在厌氧条件下在1升容量的消化器中发酵33天。产气量为280.31Nml，产率为30 Nml沼气/mg去除的COD。COD、BOD和TS的去除率分别为88%、90%和81%，然后完全破坏致病植物群，特别是大肠杆菌。这项研究提供了一个重要的充满活力的机会，产生30，950千瓦时。
This study deals with the treatment and valorization of sludge issued from the municipal wastewater treatment plant of Adrar city (southwest of Algeria). The sludge considered was a complex mixture of substances, essentially organic matters with a rate of 54%. An acute biological activity of the crude substrate was noted (1.67 106germs/1 ml). The diluted sludge with a content of 16 g/l of total solids (TS) was fermented in a digester of one litter capacity under anaerobic conditions during 33 days. The quantity of biogas produced was 280.31 Nml with a yield of 30 Nml of biogas/mg of COD removed. The COD, BOD and TS reduction yields were 88, 90 and 81% respectively, followed by a complete destruction of the pathogenic flora particularlyEscherichia coli. This study presented an important energetic opportunity by producing 30,950 KWh.
