Effects of exogenous additives on anaerobic digestion of high-salt wastewater:A review
The effects of exogenous additives such as iron-based materials,compatible solutes and carbon materials on the anaerobic digestion of high-salt wastewater were reviewed.Under the action of high salini-ty,iron and carbon materials can enhance the methanogenesis efficiency of anaerobic digestion in high sa-linity by enhancing direct interspecific electron transfer and enriching functional microorganisms.The compatible solute can be absorbed by microorganisms to balance the osmotic pressure difference,so as to help microorganisms adapt to the high-salt environment faster,and improve the anaerobic digestion treat-ment effect of high-salt wastewater.
