太湖流域污水处理厂低温生物脱氮运行模式研究

摘要

以苏州工业园区第二污水厂在冬季低温下的实际运行为例,重点分析了低温生物脱氮的影响因子,并探讨影响低温生物脱氮的因素.根据污水处理厂冬季水温特征和低温脱氮影响规律,结合污水厂运行经验和数据分析提出太湖流域污水厂低温生物脱氮的适合措施,以达到低温下保证运行效果使出水达标,并结合冬季低温下太湖流域污水厂的特点,为保证总氮出水达标提出来了相应的解决方案和措施.%Taking the actual operation of second wastewater treatment plant of Suzhou Industrial Park in winter as an example, the influencing factors of biological nitrogen removal at low temperature are analyzed, and the factors affecting biological nitrogen removal at low temperature are discussed.According to the nitrogen removal effect of sewage treatment plant in winter water temperature and low temperature characteristics, this study combined with the sewage treatment plant operation experience and data analysis of Taihu basin sewage treatment plant low temperature nitrogen and suitable measures in order to ensure the running effect of low temperature make the effluent standard, combined with the characteristics of Taihu basin sewage treatment plant under low temperature in winter, in order to ensure the effluent total nitrogen standard put forward the corresponding solutions and measures.
