城市污水前置反硝化生物脱氮工艺的动力学计算

Kinetics design on technology of biological predenitrification from municipal wastewater

通过将修正后的基质动力学参数引入前置反硝化生物脱氮工艺设计,重点介绍了利用污泥龄作为设计前置反硝化生物脱氮工艺脱氮反应器容积的设计方法.此外,还介绍了前置反硝化生物脱氮工艺系统剩余污泥量、系统需氧量和系统碱度校核的计算公式.

By introducing revised substrate kinetics parameters into the design on technology of biological predenitrification,the method which used solid retention time to design the reactor volumes and the calculation formulas for system sludge excess amount,system oxygen demand and system alkalinity check of the technology are introduced.
