校园宿舍建筑的中水回用系统水量计算

Calculation of Water Quantity in the Water Reuse System of Campus Dormitory Buildings

以某高职院校为例,根据取用水人数、用水定额以及时变化系数,计算其南北两个校区宿舍建筑的中水原水量、处理水量及回用水量,绘制水量平衡图,分析单栋宿舍和集中宿舍的中水回用差异。计算结果表明:较单一宿舍建筑而言,集中宿舍的中水回用系统设计在原水收集率和利用率方面都更高,应优先采用;校园宿舍建筑中实施中水回用,可节约淡水资源,具有一定的经济效益。

Taking a higher vocational college as an example, according to the number of water users, water quota and time-varying coefficient, the raw water quantity, treatment water quantity and reuse water quantity of dormitory buildings in the north and south campuses are calculated and the water balance diagram is drawn. The difference of water reuse between single dormitory and centralized dormitory is analyzed. The calculation results show that compared with single dormitory building, the design of reclaimed water reuse system in centralized dormitory is higher in raw water collection rate and utilization rate. Therefore, reclaimed water reuse system in centralized dormitory should be given priority. The implementation of reuse of reclaimed water in campus dormitory buildings can save fresh water resources, which has certain economic benefits.
