| 摘 要： | 对SBR法处理还原段DSD酸生产废水处理中污泥活性进行了分析。脱氢酶活性能及时准确地反映污泥活性变化,预知水质波动。在整个代谢过程中,总脱氢酶活性(Dt)和基质脱氢酶活性(Ds)变化规律相似;当了解体系大体情况时,Dt可代替Ds反映污泥活性变化。Dt与可降解COD浓度之间较好的服从莫诺关系式,Dt具有生化反应速率的意义。研究表明,在温度为30℃,葡萄糖投加量为250mg/L,有机负荷为0.6kg(/kg·d),pH值为7的条件下,脱氢酶活性最高。

| Abstract: | Dehydrogenase activity, which reflects changes of activated sludge activity in a wastewater treatment process, is investigated using a bench-top experimental device. The total dehydrogenase(Dt) can represent the variation of sludge activities during the whole metabolic course, and the relationship between Dt and degradable COD concentration follows Monod equation. |
