- 摘要:
- 对温州市南片污水处理厂提标改造工程的工艺调试过程进行了总结，并对工艺调试期间各主要处理单元的进、出水水质进行了分析。结果表明，内回流与碳源投加的耦合控制可以有效提高碳源利用率和生物脱氮效率，降低运行成本；通过控制外回流比和监测厌氧池氧化还原电位可以有效提高生物除磷效率。实践证明，采用以改良Bardenpho工艺+二沉池+加砂高密度沉淀池为核心的脱氮除磷工艺，出水水质可稳定达到浙江省《城镇污水处理厂主要水污染物排放标准》（DB 33/2169—2018）中新建城镇污水处理厂的标准。
- Abstract:
- The commissioning process of upgrading and reconstruction project in Wenzhou South wastewater treatment plant (WWTP) is summarized, and the influent and effluent quality data of each main processing unit during the commissioning process are analyzed. The results show that coupled control of internal reflux and carbon source dosing can effectively improve carbon source utilization, biological nitrogen removal efficiency and reduce operating costs. In addition, the efficiency of biological phosphorus removal can be effectively improved by controlling the proportion of external reflux and monitoring the ORP in the anaerobic tank. The effluent quality of the nitrogen and phosphorus removal process which takes improved Bardenpho process, secondary sedimentation tank, and Densadeg clarifier as the core process, can meet standards for new municipal wastewater treatment plants in the Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant (DB 33/2169-2018) in Zhejiang Province.
