Abstract: The total design scale of a waste sorting collection and treatment center in Wuxi was 510 t/d. The main construction contents included domestic waste transfer system, other kitchen waste treatment system, and associated odor and wastewater treatment systems. The “horizontal pre-compression” process was adopted for the transfer of domestic waste, while the “pretreatment + aerobic composting” process was adopted for the disposal of other kitchen waste. According to the area and concentration of wastewater and odor produced in the processes of waste compression and treatment, high and low concentration treatment systems were set up respectively to achieve environmental protection requirements through zonal and quality-based treatment. The construction of the project has realized the classification， transportation and disposal of domestic waste, and greatly reducing the impact of domestic waste transfer and treatment facilities on the surrounding environment,which can provide reference for the design of waste sorting and transfer stations in economically advanced regions in China.

Key words: waste sorting, horizontal pre-compression, aerobic composting, zonal and quality-based treatment
