Description
kitchen waste (wet waste) refers to biodegradable organic municipal solid waste, such as food raw material residues, leftover food, fruit peels and pits, and residues from traditional Chinese medicine.
kitchen waste (wet waste) is collected from disposal points and transported to transfer stations for centralized transfer and treatment. Electricity is required during treatment to maintain equipment operation. Freshwater consumption is mainly used for cleaning site equipment and supplying the spray system. Wastewater generated is treated by on-site wastewater treatment facilities before being discharged into municipal sewage networks. Off-gases produced during the treatment process are discharged into the atmosphere after treatment via alkaline spray, dry chemical adsorption, and zeolite electronic filtration. The hazardous wastes generated during the processing procedure, such as dry chemical filter media, spent zeolite, and waste filtration media, are handled and recycled by specialized institutions. The sludge produced during production is processed together with wet waste through the wet waste recycling system.
The vehicles used in the transportation and treatment process are well-sealed, ensuring no leakage of leachate.
This dataset is applicable to the transportation and treatment process of kitchen waste (wet waste).
Activity Description
This dataset represents the transfer treatment process of kitchen waste (wet waste) delivered from collection sources at transfer stations through transfer treatment equipment. It mainly includes energy consumption of the treatment equipment, waste generation and emissions, as well as auxiliary materials used for pollutant treatment within the system boundary.
