摘　　要：从建设成本、运行维护费用及附加经济效益三方面,对以正渗透技术为核心的资源型公厕系统和传统公厕系统进行费用-效益分析,并利用经济净现值评价经济可行性。结果表明,相对于传统公厕,资源型公厕的固定建设成本较高,但可以通过获得液态肥产生附加经济效益,并且节约大量的运行成本,其经济可行性远大于传统厕所。The resource-type toilet system and the traditional toilet system were compared from the three aspects including fixed construction cost, operating cost and additional economic benefit with the cost-benefit analysis. The economic net present value method was used to evaluate the economic feasibili- ty of the two kinds of toilet. The results showed that the fixed construction cost of the resource-type toilet was higher than that of the traditional toilet. While, it could obtain the additional economic benefit from the liquid fertilizer and save a lot of the operating cost. The economic feasibility of the resource-type toilet is much larger than that of the traditional toilet.
