摘要
Method and system for removing accumulated sediment at the bottom of a waste pond or lagoon of a wastewater treatment plant for a petroleum refinery. The system comprises a primary oil separation stage for separating hydrocarbons from the wastewater stream by gravity, a secondary oil removal stage and a biological treatment stage downstream of the secondary oil removal stage. A portion of the sediment from the bottom of the waste pond or lagoon is passed to the secondary oil removal stage and/or the biological treatment stage for processing with the refinery wastewater being treated in these stages.
