- 摘要:
- 利用新型除磷材料(纳微米高纯复合活性铁)替代传统的铝盐、铁盐,在采用CASS工艺的南方某污水处理厂开展了长期生产性试验。结果表明,新型除磷材料具有药剂投加量少、高效、缓释、无腐蚀、易运输、方便投加、有助于改善污泥沉降性能等优点,特别适用于进水碳源浓度低、营养比例失调的SBR、CASS等序批式工艺除磷提标需求,也可用于低碳源进水高总磷排放标准污水处理厂的除磷需求。
- Abstract:
- A new phosphorus removal material (nano-micron high purity composite active iron) was employed to replace traditional aluminum salt and iron salt and applied in a southern wastewater treatment plant using CASS process for long-term operation. The new phosphorus removal material had the advantages of a small dosage, high efficiency, slow release, no corrosion, easy transportation and convenient dosing, which could effectively improve sludge settling performance. It was especially suitable for SBR, CASS and other sequential batch processes with low influent carbon source concentration and unbalanced nutrition ratio, which could also be applied for phosphorus removal requirements of wastewater treatment plants with low influent carbon source and high total phosphorus discharge standards.
