Research progress in the treatment of high salt and high concentration organic industrial wastewater

Due to the high content of dissolved organic matter in high-salinity organic wastewater, the physicochemical treatment method is costly and difficult to achieve the desired purification effect. The biological treatment method has the advantages of economy, high efficiency, and harmlessness. Therefore, the biological method is currently the mainstream organic wastewater treatment technology. However, it is difficult to achieve high-salt organic wastewater treatment standards with traditional biological and physical-chemical treatment technologies. This article reviewed the research status of high salt and high concentration organic industrial wastewater treatments and suggested that research could be conducted on the optimization selection, biological carrier enhancement, reactor process optimization, and other aspects of high-efficiency anaerobic reactors in combination with current research hotspots to better solve and improve the problems existing in different wastewater processes.
