摘要
规划区域内再生水厂的布局及规模对该区域内污水再生利用率有很大影响,同时也影响到厂站的投资建设及后期运行管理费用。为使投资效益最大化,基于效益函数Em,建立以临界距离函数Ljh为判据的数学模型作为污水分散或集中处理再生回用的经济评价体系。在规划区域内,相同的污水再生回用率条件下,找到使整个回用水区域污水再生回用的费用最低时,再生水厂规模和位置的最佳组合。使得再生水系统规划更加合理、经济和科学,进而促进整个水环境系统的健康循环。
The layout and scale of the reclaimed water plant in the planned area have a great impact on the wastewater reclamation utilization rate in the region,and also affect the investment and construction of the plant station and the post-operation management costs.In order to maximize the investment benefit,based on the benefit function Em,a mathematical model based on the critical distance function Ljh is established as an economic evaluation system for wastewater dispersion or centralized treatment regeneration.Under the same wastewater reclamation rate in the planned area,find the best combination of the scale and location of the reclaimed water plant with the lowest cost for recycling the entire reused area.Make the reclaimed water system planning more reasonable,economical and scientific,and thus promote the healthy circulation of the entire water environment system.
