【摘要】 基于Unitank工艺进行改进,将两侧池运行方式更改为SBR运行方式,增加曝气过程。采用"水蚯蚓微生物共生系统"生物场-水力场耦合模型(T-FCASM-Hydro)分别模拟两侧池的氧传输速率控制为25d-1、50 d-1、100 d-1的出水水质。模拟结果显示氧传输速率为50d-1时出水效果最佳。将最佳方案应用于实际工艺中,优化后工艺的实测结果与模拟结果相符,出水氨氮浓度由工艺改进前的30 mg·L-1降低为2~4 mg·L-1。更多还原

【Abstract】 A new modified Process was proposed based on Unitank. Tanks on two sides were operated as SBR Process, aeration process was added into original mode. T-FCASM-Hydro coupled model was employed for simulating when KLA of aeration set to 25d-1、50 d-1、100 d-1. The simulation results showed that best water quality can be obtained if KLA of aeration was 50d-1。The results were used in the practice and measured data showed that simulation results was accordance with the real, Concentration of NH4+-N decreased from 30 mg·L-1 to 2~4 mg·L-1 by evolution of Unitank Process.更多还原
