应用ASM2D模型对曝气生物滤池工艺的模拟和优化
Mathematical Modeling and Optimization of Biological Aerated Filter Based on ASM2D
摘要
Abstract
Biological aerated filter (BAF)was one of the mainstream processes of the municipal wastewater treatment In this paper, the mathematical model of BAF based on activated sludge model 2D (ASM2D) was built, and the dynamic parameters of the model were calibrated by the sensitivity analysis. The simulation results showed that the model values of chemical oxygen demand (COD), ammonia nitrogen, total nitrogen and total phosphorus were approximately to the experiment values. The effect of methanol dosage and reflux ratio on the nitrate and total nitrogen in effluent were discussed based on the mathematical model. The denitrification process was optimized when the dosing quantity of methanol was 20 mg · L-1, the reflux ratio was 110%.关键词
