摘要
研究了用一种简单的静态物理模型取代复杂的数学动态模型,实现对实际污水处理效果的实时预测及评价的方法。应用国际水协(IWA)GPS-X模拟软件中的ASM2d模型,建立了不同进水水质和不同运行参数条件下倒置A2/O工艺出水TSS、COD、TN、NH4+-N、TP和溶解性磷酸盐浓度的数据库,结果表明,该数据库可以对倒置A2/O工艺出水指标进行预测。以预测的出水指标和实际出水指标之间的差值为指标因素,采用专家打分法确定指标权重,通过对指标的分级界定建立因素指标的隶属函数,最后运用模糊综合评判的方法实现了对倒置A2/O工艺处理效果的评价,建立了倒置A2/O工艺处理效果的数学模型。
A simple static physical model which substituted the complex mathematics dynamic model was studied to implement real - time prediction and method evaluation of real wastewater. According to ASM2d model of GPS - X simulation software of IWA, a database of TSS,COD,TN,NH4^＋ - N,TP and soluble P concentration in effluent of activated sludge in anoxic - anaero- bic - aerobic system was established on different conditions of influent quality and operation parameters. It was showed that the database could predict effluent indices of activated sludge in anoxic - anaerobic - aerobic system successfully. Taking the margin of effluent indices prediction and practical index as factors, indexes weight was determined by using the method of experts evaluation, and then membership functions of indices were established by hierarchical definition of indices. Finally, the evaluation on treatment effect of activated sludge in anoxic - anaerobic - aerobic system was implemented by the method of fuzzy comprehensive evaluation, then the mathematical model of activated sludge in anoxic - anaerobic - aerobic system was also established.
