Abstract:The 1 200 000 m3/d sewage treatment facilities and supporting sludge facilities are newly built in Zhuyuan Wastewater Treatment Plant Phase IV Project. The project is divided into two plant areas of 500 000 m3/d and 700 000 m3/d. In order to achieve the engineering goals of improving the engineering quality, shortening the construction period and reducing the environmental impact, while highlighting the purpose of technological innovation, the different forms of prefabricated assembly technology are used in the anoxic section of the biological reaction tanks in the two plant areas of the project. The different forms of prefabricated assembly technology in the project are introduced, and the BIM technology is used to simulate the whole process of the design and construction of prefabricated structure. The advantages and disadvantages are analyzed from the aspects of transportation, hoisting, stress system and efficacy of the project. The differences between the prefabricated structure and the cast-in-place structure as well as among the different prefabricated structures are summarized, which expects to provide the technical accumulation and engineering experience for the prefabricated technology of wastewater treatment plant (WWTP) in China through the implementation of the prefabricated concrete structure in Zhuyuan Wastewater Treatment Plant Phase IV Project.
