建筑物雨水收集系统可靠性优化方法

Reliability Optimization Method of Building Rainwater Collection System

设计雨水收集系统可靠性优化方法,应对三种耗水情景(WCS),即用水需求(BWN)、倾倒冲洗(PF)和全管道连接(FPC)。供应的可靠性首先通过获得雨水的复合盈余/短缺来确定,然后优化将收集的多余雨水重新分配到有短缺的建筑物。结果表明,可靠性是存储的线性函数:当供应充足时,优化的雨水存储与人均屋顶平面面积呈指数反比关系,且盈余/短缺规模与人均屋顶规划面积之间的关系遵循单相衰减模式;将剩余水从自给自足的建筑物以最佳方式再分配到有短缺的建筑物,使基本用水需求的供应可靠性从64%提高到87%,对于倾泻冲洗则从47%提高到58%,对于完全管道连接则从28%提高至29%。当前研究对改善建筑物雨水收集系统具有明确的指导意义,从而获得良好的社会收益。

The current study has designed a rainwater harvesting system reliability optimization method to deal with three water consumption scenarios(WCS),namely water demand(BWN),flushing(PF)and full pipeline connection(FPC).The reliability of the supply is first determined by obtaining a compound surplus/shortage of rainwater,and then optimizing the redistribution of the collected excess rainwater to buildings with shortages.The results show that reliability is a linear function of storage:when the supply is sufficient,the optimal rainwater storage has an inverse exponential relationship with the per capita roof area,and the relationship between the surplus/shortage scale and the per capita roof area follows a single-phase attenuation model;From self-sufficient buildings to optimally redistributed buildings,the reliability of the supply of basic water demand is increased from 64%to 87%,and for dumping flushing from 47%to 58%,for complete pipelines The connection increased from 28%to 29%.The current study has clear guiding significance for improving the rainwater collection system of buildings,and good social benefits can be obtained from it.
