Abstract:Aiming at the problems of construction land shortage for the construction of new wastewater treatment plant (WWTP) and limited land for upgrading and reconstruction of the existing WWTPs, the researches on the plane optimization land saving technology, process optimization land saving technology and vertical strengthening land saving technology for WWTP are carried out. The integrated route of land saving technology for municipal WWTP is proposed. Taking a practical WWTP as example, the application scenarios of land saving technology is expounded in detail in order to provide the technical support and guidance for the construction of land intensive WWTPs.
