摘　　要：以某生活污水处理厂为研究对象,使用BioWin软件建立其污水处理模型,筛选出与除磷效果密切相关的参数,对这些参数进行校正和优化。通过动态模拟和静态模拟对模型进行验证,确保模型的准确性。选择4种常见除磷剂进行模拟,确定所需的最佳投加浓度分别为:聚合氯化铝120 mg/L、氯化铁60 mg/L、硫酸亚铁100 mg/L、硫酸铝140 mg/L。This study takes a domestic sewage treatment plant as the research object,and its wastewater treatment model was established by using BioWin software,and the parameters closely related to the phosphorus removal effect were screened out,and these parameters were calibrated and optimised.The model was validated through dynamic and static simulation to ensure the accuracy of the model.Four common phosphorus removers were selected for simulation,and the optimal dosing concentrations required for them were determined to be:polymeric aluminium chloride 120 mg/L,ferric chloride 60 mg/L,ferrous sulphate 100 mg/L,and aluminium sulphate 140 mg/L.This study provides theoretical basis and guidance for the optimization strategy of chemical phosphorus removal for domestic wastewater plants.
