Until recently, biological treatment of sulphate-rich wastewater was rather unpopular because of the production of H2S under anaerobic conditions. Gaseous and dissolved sulphides cause physical-chemical (corrosion, odour, increased effluent chemical oxygen demand) or biological (toxicity) constraints, which may lead to process failure. Anaerobic treatment of sulphate-rich wastewater can nevertheless be applied successfully provided a proper treatment strategy is selected. The strategies currently available are discussed in relation to the aim of the treatment: i) removal of organic matter, ii) removal of sulphate or iii) removal of both. Also a whole spectrum of new biotechnological applications (removal of organic chemical oxygen demand, sulphur, nitrogen and heavy metals), recently developed based on a better insight in sulphur transformations, are discussed.
直到最近，由于在厌氧条件下会产生硫化氢，富含硫酸盐废水的生物处理一直不太受欢迎。气态和溶解的硫化物会造成物理化学（腐蚀、气味、出水化学需氧量增加）或生物（毒性）方面的问题，这可能导致处理过程失败。然而，只要选择合适的处理策略，富含硫酸盐废水的厌氧处理仍可成功应用。目前针对处理目的讨论了现有的策略：i）去除有机物，ii）去除硫酸盐，或iii）两者都去除。此外，还讨论了最近基于对硫转化的更深入了解而开发的一系列全新生物技术应用（去除有机化学需氧量、硫、氮和重金属）。
