Low-carbon design example of all-underground wastewater treatment plant
The first phase of the Guangzhou Airport Huashan Water Treatment Plant has a de-signed processing capacity of 70 000 m3/d.It adopts a fully underground permeable space design,with the main process consisting of"AAO-AO+high-load composite sedimentation tank+mic-rosand efficient sedimentation tank+denitrification deep bed filter."The effluent water quality surpasses Class Ⅳ standards,ensuring stable compliance with discharge regulations.Low-carbon operation is achieved through a switchable combination of low-carbon processes and precise control strategies.Land is conserved through the integration of a high-load secondary sedimentation tank and multifunctional modules in the operational layer.Energy efficiency is enhanced through three-dimensional transparent space design for architecture,ventilation,and lighting.Odor control in-volves a double-sealed cover for collection and processing,utilizing a partitioned composite treat-ment process for stable and compliant emissions in different zones.The ground area features an open landscape and sports park,extending the landscape design to the underground space for a comfortable operating environment.The comprehensive land use index for the project is only 0.214 m2/m3 of wastewater.
