摘要
通过对西安护城河水环境系统实际情况的分析,提出了引用护城河自循环水的新思路,拟在护城河西北角处修建的一个小型地下式中水处理站,使得污水循环利用,从经济、技术、环境保护等方面,分析比较不同自循环水利用方式,确定采用二级加压的自循环系统模型,使护城河的水循环流动起来,不仅为护城河提供了经济合理的补给水源,而且保证了护城河的水质安全。
By analyzing the practicality of water environment system in the moat, this paper puts forward a new thought about using self-circular water of the moat. A small underground reclaimed water treatment station will be built in the northwest ofthe Xi＇an Moat, realizing wastewater reclamation and reuse. From the factors such as economy, technology, environment protection, this pa- per adopts the model of adding two grade pressure in self-circular system and makes the water of moat circulate and flow. The new thought not only offers an economical and reasonable water supplement source for the moat, but also ensures the safety of water quality of the moat.
