改良A/A/O与超滤组合工艺在沙河再生水厂的应用

摘要

Recently, water shortage has been serious problems in China. Therefore, the local government improves effluent water quality through constructing reclaimed water treatment plant. According as the sewage treatment process must be based on the actual situation of the project and financial conditions, and the treatment process should be optimized to minimize operating costs and project investment while the effluent meet the water standard, this study take Shahe reclaimed water treatment plant in Changping district,Beijing, as an example to analyze the advantage of modified A/A/O and ultrafilter combined process in term of project design, process characteristics, and economic of engineering investment and operation.%近年来,我国水资源短缺日趋严重,各地通过建设再生水厂,提高水质排放标准.本文以北京昌平沙河再生水厂为例,根据项目的实际情况和资金条件选择污水处理工艺,并且在出水达标的前提下,优化处理工艺以降低运行成本和工程投资,并在综合考虑工程设计、工艺特点及经济性等方面内容的基础上,系统分析了改良A/A/O与超滤组合工艺的应用优势.
