摘要
为有效提高A/O工艺脱氮效率,以淀粉废水为研究对象,系统考察了DO、硝化液回流量、污泥回流量、SRT、进水COD与TN质量质量浓度比和HRT等因素对脱氮效率的影响,并建立了相应的控制策略,如以出水氨氮质量浓度来控制好氧区DO值,以缺氧区硝酸氮质量浓度来控制内循环回流量,以进水COD与TN质量质量浓度比或出水总氮质量浓度来控制外碳源投量.最后根据上述分析建立了A/O工艺硝化与反硝化反应专家控制系统.
How to effectively improve A/O process nitrogen removal efficiency is always a concerned problem. Nitrogen removal influence factors： DO, internal recirculaiton flow rate, sludge recycle flow rate, SRT, influent COD/TN and HRT, were clearly studied using starch wastewater, and corresponding control strategies were established, such as, using effluent ammonia concentration control DO; using nitrate concentration at the end of anoxic zone control internal recirculation flow rate; using influent COD/TN or effluent total nitrogen concentration control external carbon dose rate. Based on the above analysis, improving A/O nitrification and denitrification rate expert control system was established.
