摘　　要：以污水脱氮除磷机理为基础,从反应动力学和过程动力学角度对同步脱氮除磷的主要影响因素:溶解氧DO浓度、有机负荷、亚硝酸盐和硝酸盐浓度、污泥龄θC、流态和回流比进行了分析,指出通过模拟试验来确定运行控制参数并对其进行智能控制(IC),可保证系统稳定、高效、节能运行。Based on mechanism of removal of nitrogen and phosphorus, main affecting factors including concentration of dissolved oxygen, organic loading, sludge age, NO2--N and NO3--N, fluidity mode and circulation rate on simultaneous removal of nitrogen and phosphorus were discussed from the standpoint of reaction kinetics and process kinetics. Pilot-scale test was proposed to conduct to determine some process control parameters for intelligent control, which will be effective to keep stability, high efficiency and low energy loss of whole system.
