摘　　要：为了较合理地确定再生水水量和水质的优化分配问题,以使用再生水的净效益为目标函数,建立了能反映再生水在不同水质要求的用户之间进行水量分配的非线性规划(NLP)模型,并以西安市为例,采用该模型进行了污水再生回用系统的优化计算。结果显示,西安市在近期和中期对再生水的需求潜力较大,污水再生回用工程规模的增长率可达10%,且以集中处理回用为主,城市生态建设对再生水的最大需求量约25×104m3/d;水价对再生水在生态方面的使用影响较大,合理地调整水价可有效刺激对再生水的需求。A Nonlinear Programming （NLP） model with reclamation water distribution of different quality demand users was developed to determine reasonable optimal distribution of the wastewater reuse quantity and quality. The object was to maximize the benefit for reusing wastewater. The NLP model was applied to evaluate centralized and decentralized wastewater reuse systems in Xi＇ an City. The results indicate that the wastewater reuse potential is great; the annual increase of Wastewater reuse scales can reach 10% ; centralized reuse will be the main reuse manner in the future of Xi＇ an; the total optimized capacity for the demand of urban ecological reuse water is about 25 × 10^4 m^3/d. It is obvious that the fresh water price has a prominent influence over reclaimed water used in eco-environment ; and reasonable water pricing has certain impacts over the wastewater reuse potential.
