Recent Advances in the Biological Treatment of High-salt Wastewater

Abstract

Due to the high concentration of dissolved organic matter in wastewater and the limited efficiency of traditional physicochemical technology, high-salt wastewater has been regarded as one of the most difficult-to-treat industrial wastewaters. Alternatively, biological technology has been considered as a promising solution. However, due to the high-salt concentration, it can inhibit the growth of microorganisms in the biological treatment process, thus limiting its wide application in engineering. To date, some challenging issues still need to be solved, such as long start-up time and the complex processes of the biological technologies. This chapter summarizes the recent advances in the biological treatment of high-salt wastewater, especially the current limitations of the biological technologies and research into halophilic microorganisms.
