【摘要】 通过对一系列调蓄、渗透、净化等雨水处理构筑物进行成本分析,选取设计中关键参数,推算出其中具有代表性构筑物的费用模型。并将费用模型应用于实际工程,计算出雨水利用工程的最佳经济规模。这些费用模型在北京地区具有一定的代表性、通用性,主要适用于小区雨水利用工程的设计优化。同时,模型的推导方法对其他地区的雨水利用设计具有借鉴意义。更多还原

【Abstract】 The cost analysis of rainwater utilization was done through series of rainwater disposal processes like storage, regulation, percolation and treatment. By this way an engineering cost model for main structures of rainwater utilization has been established to deduce the key design parameters and to decide the best economical capacity of rainwater project. This model is convenient and suitable for optimal design for residential quarters in Beijing and around. However, the principles for quantitative calculation of rainwater shall be helpful for other places.更多还原
