The Shanghai Urban Domestic Waste Inland-River Collection and Transfer System is a large urban domestic waste transfer system under construction in Shanghai, which contains 3 waste transfer piers and 2 waste transfer stations. The domestic waste is compressed and loaded into containers at the transfer stations located in the transfer piers, then transferred by container ships to the landfill piers, and finally transferred to the landfill by self-unloading container trucks.
We delivered compression system-related equipment for the two waste transfer stations, namely, Yunzaobang Waste Transfer Station and Xupu Waste Transfer Station. Among them, the designed capacity of the Yunzaobang Transfer Station is 1,200 ton/day, meanwhile, the station is partnered with a new substation, waste leachate treatment station, transfer workshop odor treatment station, and other ancillary works as well as a new office building and refueling workshop. The total land area is 36,277㎡. The designed capacity of Xupu Waste Transfer Station is 2,800 ton/day, which consists of three parts of dock area, transfer station area, and living area, with a total area of 34,304㎡.
The project adopts the "compressing for five times, packing for one time" method——the pressure head of the compressor repeatedly pushes the waste into the pre-compression chamber from the movable floor feeding system, and then the waste is being compressed to enhance its density and reduce the volume, and the pressure head pushes the waste from the pre-compression chamber into a 20ft container placed on a low-floor trailer docked with the compressor in one go. At the same time, the train of trailer container leaves the loading position, and after the container’s doors are closed, it drives to the “container loading and unloading” area at the terminal.
