Anaerobic digestion is a promising technology for treating and disposing of oily sludge, but the presence oil in sludge reduces methane production volume reduction. To overcome this limitation, study creatively reports use magnetite to enhance mesophilic anaerobic elucidates underlying mechanism. Results show that addition increases production, with 5% content leading 1.42-fold increase cumulat...
Accurate analysis of the main chemical components oil-bearing sludge is an important prerequisite for effective soil remediation and resource reuse. However, precise extract difficult to achieve because mutual interference saturates, aromatics, resins, collectively called SAR, asphaltene that are introduced during chloroform extraction. In this study, SAR was efficiently extracted using n-hepta...
Background and Objective: The performance of in-vessel composting process, as one of the most effective methods of oily sludge treatment, depends on factors such as nutrients and temperature. Therefore, it is crucial to investigate the trend of changes of these factors. The aim of the present study was to investigate the trend of changes of organic carbon, nitrogen, phosphorus, and temperature ...
