改良型氧化沟工艺调试与运行

Trial-operation of improved oxidation ditch technology

介绍了娄底市第一污水处理厂一期工程设计概况和采用的改良型氧化沟脱氮除磷工艺,分析了该污水处理厂调试、培菌过程中出现的问题,并针对性地采取了一系列改进措施.在进水远低于设计值的不利条件下,通过合理培菌,不到一个月系统启动成功.监测结果表明:该工艺运行可靠,出水水质稳定、达标.

Introducing the main design content and detailed points of the first stage project which can remove phosphor and nitrogen in Loudi the first wastewater treatment plant, analyzes some problems in wastewater plant which will appear during testing bacterium cultivating and trial-operation course, and adopts a series of measures.In the influent water quality is far below the design value of the adverse conditions, by taking reasonable bacterium cultivating problem, only less than a month time for the system to start successfully.The data indicates that operation and water quality of efflu-ent is steady, and the plant can achieve a regular function.
