Performance evaluation of the emerging rural sewage treatment facilities in China

Urban water pollution has been well controlled by strict management in the past few decades in China. Thus, the central government started to place emphasis on rural water pollution, and increasing number of sewage treatment facilities have been constructed, and currently, they are operating in China. Therefore, thoroughly assessing the operating conditions and the performance of these facilities is important. This article analyzes life cycle assessment and life cycle cost to evaluate the environmental and economic performance of four common technologies to determine how the emerging rural sewage treatment facilities in China are running. The results showed that the plant-adopted anaerobic-anoxic?oxic process was an optimal scheme for lower environmental impact that was also cost-effective. All technologies had similar impacts on eleven environmental categories. Due to cement consumption during the construction phase and electricity consumption during the operation phase, the marine aquatic ecotoxicity potential was the greatest contributor, accounting for approximately 90% of the total potential impact. In addition, this research revealed that electricity consumption during the operation phase was responsible for almost all environmental impact categories, except for eutrophication potential and ozone layer depletion potential categories. Lastly, scenario analysis indicated that reusing treated water and adjusting power structure could be useful measures to promote the sustainable development of rural water environments.
