摘要: 本研究采用升流式填充床厌氧反应器，考察温度变化对反应器处理高硫酸盐废水性能的影响。结果表明，在COD/SO42-为1和HRT为16 h的实验条件下，当反应器温度为30℃时，硫酸盐和有机物均得到高效去除，分别达到98.60%和89.01%，当温度降低到10℃时，硫酸盐和有机物去除率大幅度下降，最低降至41.45%和39.93%。温度的降低导致胞外聚合物(EPS)中多糖(PS)和蛋白质(PN)含量同步增加，由于葡萄糖作为碳源能够促进微生物分泌更多的胞外酶，从而导致EPS中的PN含量大于PS含量。
Abstract: The effect of temperature changes on the pollution removal performance was investigated with an upflow packed bed anaerobic reactor in treating high sulfate wastewater in this study. The results showed that under the experimental conditions: COD/SO42- ratio of 1, HRT of 16 hours and reactor temperature of 30˚C, both sulfate and organic matter were efficiently removed, reaching 98.60% and 89.01%, respectively. When the temperature drops to 10˚C, the removal rates of sulfate and organic matter significantly decrease, with the lowest dropping to 41.45% and 39.93%. The decrease in temperature could lead to a synchronous increase in the content of polysaccharides (PS) and proteins (PN) in extracellular polymers (EPS). Due to glucose serving as a carbon source, it could promote the secretion of more extracellular enzymes by microorganisms, resulting in a higher PN content than PS content in EPS.
