摘要
本文依据北京市中水设施运行现状调查结果,着重分析了处理规模与运行成本后认为,现有中水处理规模偏小是造成中水成本偏高的主要原因.建议日处理规模以控制在150m^3以上为宜,并相应提出了扩大中水使用规模等若干解决办法.本文还就建设中水设施的环境经济效益进行了投入产出分析,得出中水的投入产出比为1:4.83.
The investigation on the operating status of intermediate water system (IWS) in Beijing has been shown that the high operating cost of IWS is mainly caused by too small capacity. A daily capacity of IWS much than 150 cubic meters is recommended and some measures to expand the capacity of IWS are proposed. The environmental input-output analysis of IWS gives an input-output rate of 1:4. 83, this will be a basis of economical analysis for wastewater reuse in area of water shortage.
