Abstract: In demonstration and extension of rural sewage treatment processing facilities, quantified evaluation of the technology solutions can improve the
scientific nature of decisions-making. In this paper, a rural sewage treatment technology evaluation index system considering technology effectiveness,
economy and efficiency was established, and the indicators included COD Removal Efficiency, NH4+ -N Removal Efficiency, TP Removal Efficiency,
Construction Cost, Operating Cost, Land occupation Area, Economic Benefits, Technology Stability, Management Easiness Degree and Ecological
Coordination Degree. The rural sewage treatment technology evaluation method based on fuzzy advantages and disadvantages coefficient was proposed. The
method includes initially screening the alternative solutions, evaluating the technology performance and the technology demands degrees from the study area
with the indications systems and the fuzzy evaluation method, and building the pros and cons relationship matrix between the alternative solutions and
calculating the pros and cons coefficient to obtain the optional solution. A case study was conducted in Youyi Village in Changzhou City, and the
evaluation results matched the local conditions. The method considers not only the technical performance of rural sewage treatment technology, but also the
applicability of the sewage treatment for rural areas and the matching between the technology performance and the technology demand. The method can
serve as the decision analysis tool for sewage treatment technology demonstration and promotion in rural areas.
Keywords: rural sewage; treatment technology; index system; advantages and disadvantages coefficient method; fuzzy evaluation
