| 摘 要： | 建立污泥停留时间为5 d和10 d的两套厌氧反应器系统。通过对比两厌氧反应器污泥中有机物以及金属指标,研究厌氧条件下金属与有机物的释放规律。研究表明,污泥絮体中K、Ca、Mg、Fe、Al五种常见金属在两厌氧反应器中均发生释放作用,且金属的释放规律与蛋白质、溶解性COD的释放规律相一致,Na变化较小,三价金属结合的胞外蛋白质存在离解释放机制。10D的反应系统的厌氧环境相较于5D更加稳定,且污泥浓度有下降趋势,可预期有更好污泥减量的效果。 |
| 关 键 词： | 厌氧 污泥 金属释放 有机物释放 |

| Abstract: | Two sets of anaerobic reactors were established as the SRT =5 and SRT=10 sepa- rately. Through the comparison of the contents of organics and metal of the sludge in two re- actors, the research analyses the release rule of metal and organic matter under anaerobic condition. The results show that 5 kinds of common metal were both released in two anaerobic reactors, and the release rule of protein and sCOD show the same rule. And there is dissocia- tion and release mechanism happened to extracellular protein combined with trivalent mental. The contents of dissolved indexes of 10-day system are higher than 5-day system, which in- dicates the better effect of sludge reduction in longer SRT system. |
