Abstract

An expanded-bed granular activated carbon (GAC) anaerobic reactor was developed to treat terephthalate-containing wastewater. Terephthalate inhibits biological anaerobic degradation of terephthalate and methane production when present at a concentration of more than 150 mg/L. In the GAC anaerobic reactor developed here, degradation of terephthalate and other organic compounds occurred smoothly and stably with removal and methane fermentation ratios of more than 90% under a chemical oxygen demand (COD) loading rate of 4 kg COD/(m(3) d) and a terephthalate loading rate of 1 kg terephthalate/(m(3) d).

摘要

开发了一种膨胀床颗粒活性炭（GAC）厌氧反应器来处理含对苯二甲酸的废水。当对苯二甲酸浓度超过150 mg/L时，它会抑制对苯二甲酸的生物厌氧降解和甲烷生成。在此开发的GAC厌氧反应器中，在化学需氧量（COD）负荷率为4 kg COD/(m³·d)和对苯二甲酸负荷率为1 kg对苯二甲酸/(m³·d)的条件下，对苯二甲酸和其他有机化合物的降解顺利且稳定地发生，去除率和甲烷发酵率超过90%。
