| 摘 要： | 以活性红KE-3B为例,考察了中高温条件下盐度、VFAs(挥发性脂肪酸)、污泥的吸附等对其厌氧脱色的影响,从产气量和生物气组分来探讨活性红KE-3B厌氧脱色的形式和程度,并对活性红KE-3B的厌氧脱色机理作初步探讨.结果显示,高温更有利于活性红KE-3B的脱色,脱色率可以达到98%以上,维持高脱色率的最高盐度为600mmol·L-1,并且在脱色过程中,没有发现活性红KE-3B被矿化,其主要脱色形式为初级降解.

| Abstract: | Based on an anaerobic batch test system, the effects of salt, volatile fatty acids (VFAs) and sludge adsorption on decolorization of reactive red KE-3B were studied in details. The form and extent of anaerobic decolorization were detected by gas production amount and composition, and the degradation mechanism of reactive red KE-3B reduction was also discussed. The results indicated that the decolorization rate was higher (more than 98%) under thermophilic condition than that under mesophilic condition when the salt concentration was less than 600 mmol·L-1. The evidence of mineralization of reactive red KE-3B was not detected, and we found that the main decolorization form was primary biodegradation. |
