浅析高速铁路动车段给排水节水节能

Analysis on Water and Energy Conservation in High Speed Railway MU Depot

当前水资源匮乏、能源紧张,节水节能关系到我国经济和社会的发展,是一项长远的战略方针,也是当前一项极为紧迫的任务。文章结合高速铁路动车段的特点,从生产废水回用系统、雨水回用系统、下凹式绿地这3个方面着手分析,提出了动车段给排水及消防节能节水的设计思路,并对各项节水节能措施进行了经济技术比较。同时,生产废水回用系统在考虑中水回用系统的前提下给出了给水管道系统的优化方案;雨水利用虽说在现今动车段内的使用条件还并不成熟,但仍然有广阔的发展前景;下凹式绿地作为一种新型的雨水渗透技术,在动车段内能起到良好的排洪防涝、节能减排的作用,经过理论结合实际的分析,认为下凹式绿地在高速铁路行业具有一定的推广价值。

As the current scarce supply of water has threatened the socioeconomic development in our country,water and energy conservation has become a long-range stratage and an urgent task.Combined with the features of high speed rail-way MU depots,this paper presents a new design of water and energy conservation for water supply and drainage and fire control in MU depots based on analysis of reuse of wasterwater,recycling of rainwater and cultivation of low leveation green belts,and economic and technical comparision has been carried out for each water and energy conservation meas-ures.Meanwhile,a proposal for optimizing water supply pipe system is provided when reuse of recycled water is taken in-to consideration.Rainwater utilization is not realistic at present,yet it has a vast potential for future development.Low leveation green belt,an updated meathod for rain infiltration,provides a sound drainage of floodwater in the area of MU depot.Integrating theory with practice,the author has concluded that low elevation green belt is worth to be introduced in a high speed railway MU depot.
