| 中文摘要: |
| 为了保障饮水健康,国外、国内先后兴起了管道直饮水,但这种供水系统不仅存在诸多结构性的技术缺陷,而且建设难度大、工程造价高、管理难到位、使用水费贵,为此,课题组在有关科研项目的基础上构建了终端分质供水系统,研发了分质供水净水机,建设了终端分质供水示范工程,开展了实证与应用研究,该系统无需建设户外的净水设施、加压设备、供水管网、回水管路、设备用房,直接在用水终端设置分质供水净水机,进行分类处理与分流利用,其中直饮水实现了“现制现饮”；清洁水也没有滞留,避免了微生物滋生,水质优于自来水,能满足厨房用水的需要；尾水与自来水混合为冲洗水,用于洗衣、沐浴、冲厕等。相较于管道直饮水系统,该系统具有系统结构科学合理、水力作用影响较小、二次污染得以避免、净水水质稳定可靠、系统自净能力突出、节能节水效果显著、改造和安装难度低、经济性和适应性强等技术优势。本文的创新点在于：一是构建了终端分质供水,解决了传统管道分质供水存在的结构性技术缺陷；二是研发的分质供水净水机,使终端分质供水模式可落地,可作为管道分质供水系统、传统净水机的补充与换代产品。 |

| In order to ensure the health of drinking water, pipeline direct drinking water has emerged both domestically and internationally. However, this type of water supply system not only has many structural technical defects, but also has high construction difficulty, engineering cost, management difficulty, and high water usage costs. Therefore, the research team has built a terminal differentiated water supply system based on relevant scientific research projects, developed a differentiated water supply water purifier, and built a terminal differentiated water supply demonstration project, Empirical and applied research has been conducted, and the system does not require the construction of outdoor water purification facilities, pressurized equipment, water supply pipelines, return pipelines, or equipment rooms. Instead, a separate quality water supply water purifier is directly installed at the water terminal for classification treatment and diversion utilization. Direct drinking water achieves "instant drinking"; Clean water is not retained, avoiding the growth of microorganisms, and the water quality is better than tap water, which can meet the needs of kitchen water; Tail water mixed with tap water is used as flushing water for laundry, bathing, toilet flushing, etc. Compared to the pipeline direct drinking water system, this system has technological advantages such as a scientifically reasonable system structure, less hydraulic impact, avoidance of secondary pollution, stable and reliable purified water quality, outstanding self-cleaning ability of the system, significant energy-saving and water-saving effects, low difficulty in renovation and installation, strong economy and adaptability. The innovation of this article lies in: firstly, the construction of terminal differentiated water supply solves the structural technical defects of traditional pipeline differentiated water supply; The second is the development of differentiated water supply purifiers, which enable the implementation of terminal differentiated water supply mode and can serve as a supplement and replacement product for pipeline differentiated water supply systems and traditional water purifiers. |
