摘要
介绍了大连开发区污水处理一厂工艺升级改造工程的设计参数、设计流程。工程设计中在充分考虑利用原有设施、设备的基础上实现污水处理厂扩容及提标改造,将原A/O工艺改造为改良A2/O工艺,并可根据需要按改良A2/O工艺或倒置A2/O工艺运行。设计同时还考虑污水处理厂扩建升级过程中的不停产措施,为类似扩建改造工程提供参考借鉴。
The design parameters and process flow of the upgrading and reconstruction project of WWTP No. 1 in Dalian Economic and Technological Development Zone were introduced. The upgrading and reconstruction of WWTP were designed and implemented based on the full use of existing facilities and equipment. The original A/O process was unit could be operated in form of the improved the need. The continuous operation during the design, which provided a reference for similar replaced by the improved A2/O process, and the treatment A2/O process and the inversed A2/O process according to upgrading and reconstruction was taken into account in the upgrading and reconstruction projects.
