CAST分段进水强化脱氮工艺特性研究

CAST分段进水强化脱氮工艺技术采用优化运行时序、调整充水比等方法，在污废水处理中利用原水中的有机物作为反硝化碳源，具有较好的脱氮性能，在节省外加碳源投加量的基础上，不仅保持了传统CAST工艺的优点，强化了脱氮效果，并且在系统启动时间、抗冲击能力、污泥负荷承担能力和节能降耗方面也均优于水厂传统的CAST系统，值得大范围推广应用。

Characteristic Research on Strengthening Denitriifcation Technology in CAST Subsection Water Inlfow

The strengthening denitriifcation technology in CAST water inlfow in subsection adopts the methods of op-timizing operation hour order and others. By using the organism in the original water as denitriifcation carbon source in the wastewater treatment, it has the best denitriifcation capability. Based on the addition of carbon source and quantum, it maintains the merit of the traditional CAST technology and strengthens the effect of denitriifcation. It excels the traditional CAST system in the system start-up time, anti-impact power, load power of sludge, energy saving and consumption reduction. It is good for popularization and application at a great range.
