宁波市基于污水厂工艺全流程分析及优化运行模式的实践

Practice on Whole Process Analysis and Optimized Operation Mode of Sewage Treatment Plants in Ningbo

在国家对水环境不断重视、排水标准不断提高的背景下,有必要对现有污水处理厂进行详细深入的水质特性和运行现状调研分析,提出有针对性的优化运行和提标改造建议,保证污水厂稳定运行。宁波市城市排水有限公司将污水厂全流程工艺分析工作列入提升污水主业运营水平的管理范畴,对现有三座污水厂进行了工艺全流程分析及优化的实践,详细介绍了A厂的实践结果,总结了三座污水厂的共性问题,按照"发现问题-制订研究方案-调试及分析研判-确定解决措施"的工作思路,建立排水公司自主的应对体系和操作流程,在此基础上逐步形成优化运行的"一厂一策",并探索春、夏、秋、冬等不同季节各污水厂工艺的高效运行模式。

Under the background of nationally continuous attention to water environment and improvement of drainage standards,it is necessary to provide targeted proposals for optimal operation and upgrading reconstruction based on detailed investigation and analysis on the water quality characteristics and operation status of the existing sewage treatment plants,so as to improve the stable operation of sewage treatment plant. Ningbo Municipal Sewerage Co. Ltd. has included whole process analysis into the management scope of improving main industry operation level and practiced it in the existing three sewage treatment plants. The practical results of plant A were elaborated,and the common problems of the three sewage treatment plants were summarized. According to the working ideas of "identifying problems-developing research plans-analyzing and judging-finding solutions",the company has set up its own response system and operation process,and gradually formed the "one plant one policy"to explore the efficient operation mode of each sewage treatment plant in different seasons.
