- Abstract:
- Xianju wastewater treatment plant phase Ⅱ project is the key project of “five water co-treatment” in Taizhou City. The multi-stage combined process consists of pretreatment, two-stage biochemical treatment, advanced treatment, constructed wetland and disinfection. The effluent quality meets the quasi class Ⅳ limit specified in Effluent Indicators and Standard Limits of Taizhou Urban Sewage Treatment Plant (Trial). In terms of energy recovery, energy saving and consumption reduction, 16% self-sufficiency of electricity in the plant was achieved and 16% exogenous CO2 was correspondingly reduced by fully utilizing the upper space of sewage treatment structures to implement photovoltaic power generation technology. The constructed wetland realized the deep purification of effluent quality from the first class A standard to quasi class Ⅳ standard, and the electricity and maintenance cost only accounted for 15% of the total operating cost. In addition, constructed wetlands were also a part of sponge city construction, which effectively accepted and recycled rainfall combined with the construction of surrounding sponge factories. The project realized digital twinning and intelligent management through the comprehensive implementation of BIM and digitalization technology to ensure the efficient implementation of the design scheme. This project fully demonstrated the successful application and practice of green municipal concept in municipal wastewater treatment plant under carbon peak and neutrality goals.
