Abstract

Abstract

Under the background of China's carbon peak and carbon neutralization goals,there is a lack of quantitative comprehensive impact assessment on process design in carbon-neutral planning of the wastewater treatment industry.Therefore,based on the LCA framework,a comprehensive impact assessment model of carbon footprint,environment,and economy of the whole life cycle (LCA-CEE) was established.And the model was used to analyse the effects of two different sludge treatment processes in sewage treatment plants (A plant:sludge landfill;B plant:sludge-kitchen waste co-digestion).The comprehensive impact assessment and comparative analysis were conducted on energy consumption,material consumption and pollution discharge in the construction,operation and demolition stages within 30 years.The results showed that the power generation of cogeneration system in plant B reached 38.9 MW·h,realizing energy self-sufficiency and with a carbon neutralization rate up to 133%.Compared with plant A,the economic benefit was 1.6 times higher and the environmental impact was significantly reduced.The LCA-CEE model developed in this study evaluated the energy-saving and emission reduction path from the whole process,providing theoretical support for carbon neutrality planning of the sewage treatment industry.
