活性污泥糖类物质含量与其除磷能力的关系
- Influence of sludge carbohydrate content on enhanced biological phosphate removal
- 摘要：分别以葡萄糖和醋酸为主要进水有机物,通过2只序批式反应器的连续运行,探索了污水生物除磷工艺中活性污泥糖类物质含量的变化与其摄磷能力的关系,发现将活性污泥糖类物质含量控制在较低水平是实现高效生物除磷的一个重要条件。
- Abstract：The relation between sludge carbohydrate (CH) content and phosphate (P) removal performance was studied in two sequencing batch reactors (SBRs) exhibiting enhanced biological phosphate removal (EBPR).Glucose and acetate were used as the main organic substrates for the two SBRs,respectively.The P removal performance was excellent when the sludge CH content ranged from 8% to 10% (CH/MLSS),but it declined concomitantly as sludge CH content increased beyond this range.Sludge CH content was found to be a reliable parameter representing the sludge capacity of P removal.The study,as a whole,suggests that the control of sludge CH content to low levels is a prerequisite for achieving enhanced P removla in EBPR process.
