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.
