Description
Technical Field
The utility model belongs to the technical field of water supply system, in particular to regional water supply system of annular water supply network direct drinking water.
Background
According to statistics, the current water for residents can be generally regarded as direct drinking water and clean water. The direct drinking water is generally mineral water, purified water or packaged drinking water, and tap water supplied by a tap water plant is generally used as cleaning and cleaning water. Tap water from a tap water plant meets the national drinking standard, but residents also need to purchase drinking water additionally.
The reason for this phenomenon is two-fold: firstly, the water supply mode of tap water is that a single pipeline of a water supply pipeline enters a house (namely, a tree-shaped water supply and delivery pipeline network), and the limitation of the water supply mode is that the peak of water consumption generally has a time interval property, is concentrated in the morning, the evening and most off-peak time intervals, and the water in the pipeline is in a static state in the pipeline, so that the tap water is secondarily deteriorated due to the breeding of microorganisms in the pipeline and cannot be directly drunk; secondly, the operation of disinfection, cleaning and sterilization of the single water supply pipeline is difficult, and some pipelines can see the obvious attached substances such as sludge, rust and the like on the wall of the water supply pipeline in the maintenance process, so that residents do not feel distrusted to the tap water and dare not to drink directly.
In conclusion, the water supply and delivery pipe networks for domestic water and production water are tree-shaped water supply pipe networks, namely main pipelines and branch pipelines, and only water supply pipelines and water return pipelines exist. Therefore, most of the time, the water can not flow in the pipeline, so that the microorganisms in the pipeline are bred to deteriorate the tap water, and the water sanitation index is reduced.
