城市污水再生利用系统水量平衡探讨

分析了城市污水再生利用系统中水量平衡设计存在的问题 ,包括水量设计能力过大或过小、未考虑水量的时间波动、未区分不同水质的来水、未结合空间分布等 ,提出借用社会学中常用的微观模拟的思想 ,将城市分为区域、小区和单元。通过分析不同单元中个人的用水行为及特征 ,进而分析污水再生利用的情况。此外还指出了利用微观模拟模型计算水量平衡的优缺点

Discussion on Water Balance of Urban Wastewater Reclamation and Reuse System

After making analysis on the problems existing in the design of water balance in urban wastewater reclamation and reuse system,including over-capacity or under-capacity,neglect of time fluctuation in amount of water and space distribution,and making no distinction for inlet water with different water quality,etc.,it was proposed that the city was divided into district,village and unit by means of micro-simulation idea usually used in sociology.After making analysis on individual's water consumption behavior and characteristics in different units,wastewater reclamation and reuse were analyzed.In addition,merits and demerits in calculation of water balance by using micro-simulation model were presented.
