Sulphate-containing wastewaters from the paper and board industry, molasses-based fermentation industries and edible oil refineries present difficulties during anaerobic treatment, leading to problems of toxicity, reduction in methane yield, odour and corrosion. The microbiology and biochemistry of dissimilatory sulphate reduction are reviewed in order to illustrate the potential competition between sulphate reducers and other anaerobes involved in the sequential anaerobic mineralisation process. The theoretical considerations which influence the outcome of competition between sulphate reducers and fermentative, syntrophic, homoacetogenic and methanogenic bacteria are discussed. The actual outcome, under the varying influent organic composition and strength and sulfate concentrations which prevail during digestion of industrial wastewaters, may be quite different to that predicted by thermodynamic or kinetic considerations. The factors governing competitive interactions between SRB and other anaerobes involved in methanogenesis is discussed in the context of literature data on sulphate wastewater treatment and with particular reference to laboratory and full-scale digestion of citric acid production wastewater.
造纸及纸板工业、糖蜜基发酵工业和食用油精炼厂产生的含硫酸盐废水在厌氧处理过程中存在困难，会导致毒性、甲烷产量降低、气味和腐蚀等问题。本文综述了异化硫酸盐还原的微生物学和生物化学，以说明硫酸盐还原菌与参与顺序厌氧矿化过程的其他厌氧菌之间的潜在竞争。讨论了影响硫酸盐还原菌与发酵菌、互营菌、同型产乙酸菌和产甲烷菌之间竞争结果的理论因素。在工业废水消化过程中，不同的进水有机组成、强度和硫酸盐浓度下的实际结果可能与热力学或动力学考虑所预测的结果有很大不同。结合硫酸盐废水处理的文献数据，特别是柠檬酸生产废水的实验室和全规模消化数据，讨论了控制硫酸盐还原菌与参与产甲烷过程的其他厌氧菌之间竞争相互作用的因素。
