摘　　要：再生水利用系统建设需要综合考虑资源、环境、社会等外部效益,合理制定再生水水价才能有效激励政府和用水户选择再生水。通过研究构建了费用效益分析计算体系,综合考虑了再生水项目的建设运营费用和再生水项目相对其他水源供水产生的资源环境效益,利用增量净年值法评价再生水项目经济可行性,并提出替代方案法计算再生水的合理定价。将该方法应用于安吉县某工业用水项目的再生水定价中。通过分析可知:再生水供水方案相对自来水供水和西苕溪取水方案经济可行;在兼顾了不增加用水户用水负担和保护水资源环境的前提下,采用替代方案法计算得到再生水合理定价区间为1.26~1.41元/m^(3).The construction of a reclaimed water utilization system has to comprehensively consider external benefits,such as resources,environment,and society to get a reasonable price for reclaimed water to effectively stimulate the government and water users to choose reclaimed water.In this study,a cost-benefit analysis calculation system was constructed,which comprehensively considered the construction and operation costs of the reclaimed water project and the resource and environmental benefits generated by the reclaimed water project relative to other water sources.The incremental net present value method was used to evaluate the economic feasibility of the project,and the alternative approach method was proposed to calculate the reasonable pricing of reclaimed water.Through analysis of an industrial water supply project in Anji County,it was found that the reclaimed water supply scheme was economically feasible compared to the tap water supply scheme and a natural water intake scheme.The reasonable pricing range was 1.26~1.41 yuan/m^(3) calculated by the alternative approach method,in the premise of both the economic burden of water users,protection of water resources and the environment being taken into account.
