复合式接触氧化-过滤沉淀工艺处理医院污水

结合工程实例介绍了复合式接触氧化-过滤沉淀工艺在医院污水处理中的应用。对接触氧化进行了改进,把原有接触氧化池分成若干单元池,通过控制曝气量,营造好氧、缺氧环境,以完成脱碳和硝化反硝化脱氮过程,并辅以过滤沉淀技术。工程实践证明,用该工艺处理完全能够达到相关排放标准的要求,是一种适宜于医院污水处理的经济、高效的污水处理技术。

USING BIOLOGICAL CONTACT OXIDATION AND FILTERING SEDIMENTATION PROCESS TO TREAT HOSPITAL SEWAGE

Combined with engineering example,the usage of the biological contact oxidation and filtering sedimentation process in treatment of the hospital sewage was introduced.It was improved that the original contact oxidation ponds are divided into several units.Oxic or anaerobic environment was built in different units through controlling the quantity of aeration in order to remove the organic carbon and nitrogen from the sewage by a series of nitrification and dentrification reactions.By the aid of the filtering sedimentation technology,the biological contact oxidation and filtering sedimentation process has a series of advantages.It has been proved that the sewage treated through the biological contact oxidation and filtering sedimentation process is up to the relevant standards and the process is an economical and efficient technology for wastewater treatment.
