【摘要】 近年来，在传统污水处理工艺的基础上，已经研究开发了许多污水处理新工艺。在传统生物膜法的基础上研究开发的曝气生物滤池（BAF—Biological Aerated Filters），具有体积小、处理效率高、出水水质好、流程简单等优点，在欧洲、美国和日本被广泛地用于处理生活污水和工业废水。二十世纪九十年代以来，国内对该工艺进行了大量的研究，并致力于使其国产化。本文涉及的BIOFOR^?（Biological Filtration Oxygenated Reactor）曝气生物滤池是法国Degremont（得利满）集团的技术，在国内为首例应用。对该工艺运行效果的研究和探索，对其在我国的进一步应用是极为必要的。 本文通过对相关文献的综述，阐述了目前城市污水处理技术研究进展和实践应用现状，并以工程实例对各种处理工艺进行了比较。主要通过对采用BIOFOR^?曝气生物滤池工艺的大连马栏河污水处理厂运行效果的总体评价，对运行数据、工艺参数进行了分析和讨论，并与其它污水处理工艺进行对比，总结出了该工艺的特点和优点。 研究结果表明：采用BIOFOR（?）曝气生物滤池工艺的大连马栏河污水处理厂处理效果稳定，满负荷连续运行，进水污染物指标略低于设计值，出水水质低于设计标准，COD≤40 mg／L，BOD₅≤10 mg／L，SS≤10 mg／L，NH₄-N≤5 mg／L。出水的主要水质指标达到新颁发的国家标准—《城市污水再生利用城市杂用水水质》标准（GB／T 18920—2002），根据用水性质可直接回用或作为污水再生利用的优质水源。更多还原

【Abstract】 In recent years many new water treatment technologies have been studied and developed on the basis of the traditional wastewater treatment processes. The BAF (Biological Aerated Filters) process has been widely applied in treating municipal and industrial wastewater in Europe, USA and Japan for its advantages in compact structure, high treatment efficiency, quality effluent and simplified process flow. Since 1990’s many researches have been made on the application and localization of this process in our country. The BIOFOR aerated filters process hereby mentioned is a technology developed by France Degremont Group and applied in China for the first time. Studies and researches on its operation efficiency are remarkably necessary for its further application in China.With a comprehensive citing from related literature, this thesis demonstrates the latest development in wastewater treatment technology research and the current situation of its application in practice, taking practical projects for examples and making contrast between several processes. After an overall evaluation to Dalian Malanhe Wastewater Treatment Plant adopting BIOFOR process, operation data and process parameters are studied and analyzed, and comparison of this process with other wastewater treatment processes are made, with a summary to its characteristics and advantages.Researches improve that by applying BIOFOR aerated filters Dalian Malanhe Wastewater Treatment Plant achieves stable treatment efficiency, continuous operation with full loads, with influent pollutant standards lower than designed standards and effluent quality lower than designed standards, COD<40 mg/L, BOD5 <10 mg/L, SS<10 mg/L, NH4-N<5 mg/L. The values of the main parameters representing the effluent quality reach the standards stipulated in the latest National Standards for Reuse of Urban Wastewater and Miscellaneous Uses (GB/T 18920-2002). The effluent will be directly reused or become an excellent water resource for recycling of wastewater.更多还原
