- 摘要:
- 为满足区域内污水处理需求，改善水生态环境，促进可持续发展，成都新建1座污水处理厂，近期设计规模8×104 m3/d，采用地下式建设形式并配套建设地面活水公园，以减少臭气、噪声影响并改善与城市景观的协调性。针对受纳水体环境容量不足且排污口距离国控断面过近而面临的严格排放要求，污水处理采用AAOA-MBR-臭氧催化氧化组合工艺，强化生物脱氮除磷并深度处理难降解有机物。主要出水指标BOD5、COD、NH3-N和TP等执行《地表水环境质量标准》（GB 3838—2002）中Ⅲ类水标准，TN执行《四川省岷江、沱江流域水污染物排放标准》（DB51/2311—2016）。实际运行数据显示，污水处理工艺稳定可靠，出水COD、NH3-N、TP、TN均值分别为10.02、0.37、0.15和6.40 mg/L，优于设计标准，可为高排放标准下城市污水处理提供技术参考。
- Abstract:
- A new wastewater treatment plant was constructed in Chengdu to address regional sewage treatment needs, enhance the aquatic ecological environment, and support sustainable urban development. The wastewater treatment plant has a designed capacity of 8×104 m3/d for the initial phase and features an underground configuration. This design incorporated a surface ecological park to mitigate odor and noise emissions and to improve integration with the surrounding urban landscape. In response to the stringent discharge requirements arising from the limited environmental capacity of the receiving water body and the proximity of the discharge outlet to a national monitoring section, the AAOA-MBR-catalytic ozonation integrated process was implemented for enhancing biological nitrogen and phosphorus removal efficiencies while enabling advanced degradation of refractory organic compounds. The primary effluent indicators, including BOD5, COD, NH3-N, and TP, should meet the class Ⅲ surface water quality requirement specified in Environmental Quality Standards for Surface Water (GB 3838-2002), while TN should conform to the requirement set forth in Water Pollution Discharge Standards for Minjiang and Tuojiang River Basins in Sichuan Province (DB51/2311-2016). Actual operational data indicated that the wastewater treatment process was stable and reliable, and the average COD, NH3-N, TP, and TN in the effluent were 10.02 mg/L, 0.37 mg/L, 0.15 mg/L, and 6.40 mg/L, respectively, all of which met and were superior to the designed discharge standards, thereby providing valuable technical references for urban wastewater treatment under stringent regulatory requirements.
