摘　　要：通过收集某化工企业污水处理厂15个月的历史运行数据,并对数据进行分析处理,同时根据建模需要对污水场生化段进水进行补充实验,最终获得该污水厂的进水水质各项指标的详细数据,在此基础上利用专业的污水系统模拟软件Biowin建立该污水厂的生化段模型,主要包括生化反应单元、沉淀单元、加药单元、膜生物反应单元等,旨在通过机理模型分析该污水处理厂运行过程中存在的潜在风险及运行瓶颈。经调研、数据分析及模拟研究发现,当该污水厂生化段进水(即调节池出水)氨氮浓度超过150mg/L时,中间沉淀池出水水质检测氨氮浓度较高,氨氮去除率较低,表明一级生化段硝化反应受限。在后续二级生化处理中,主要去除氨氮和TN,此时需要向系统投加碳源,通过模拟分析,可通过增加系统的甲醇投加量来降低出水TN浓度。当甲醇投加量控制在18~23m^(3)/d,MBR池回流比为300%、硝化液回流比为100%时,能够较好地控制出水TN浓度。By collecting,analyzing and processing the historical operation data over a 15-month period of the sewage treatment plant of a chemical enterprise and conducting supplementary experiments on the influent water of the biochemical section of the sewage plant according to modeling needs,the detailed data of various indicators of influent water quality of the sewage plant were finally obtained.On this basis,BioWin,a professional sewage system simulation sofware,was used to establish the biochemical section model of the sewage plant,which mainly includes biochemical reaction unit,precipitation unit,dose-adding unit and membrane biological reaction unit,aiming to analyze the potential risks and operation bottlenecks during the operation of the sewage plant using the mechanism model.Through investigation,data analysis and simulation study,it was found that when the ammonia nitrogen concentration of the influent water of the biochemical section of the sewage plant(i.e.,the effluent water from the regulating tank)exceeds 150mg/L,the ammonia nitrogen concentration of the effluent water from the intermediate sedimentation tank is high and the ammonia nitrogen removal rate is low,indicating that the nitrification reaction in the primary biochemical section is limited.The subsequent secondary biochemical treatment mainly removes ammonia nitrogen and TN,and carbon sources need to be added to the system at this time.Through simulation analysis,the TN concentration of effluent water can be reduced by increasing the amount of methanol added to the system.When the methanol dosage is controlled between 18m^(3)/d and 23m^(3)/d,the reflux ratio of MBR pool is 300% and the reflux ratio of nitrification solution is 100%,the TN concentration of effluent water can be well controlled.
