A device and method for flexible switching of multiple water sources in a community based on water quality conditions

Abstract

The application discloses community multi-water-source flexible switching equipment based on the water quality state and a method thereof. The equipment comprises a first water quality sensor which is used for monitoring water quality of a reuse water main inlet pipe of a reuse water supply system in real time; a second water quality sensor which is used for monitoring water quality of a river water source main inlet pipeline of a heating medium water supply system in real time; a first electrical two-way regulating valve which is used for performing automatic valve switching operation when the real-time water quality value of reuse water is less than a first preset value so as to switch the reuse water source in the reuse water main inlet pipe to a tap water source; and a second electric two-way regulating valve which is used for performing automatic valve switching operation when the real-time water quality value of the river water source is less than a second preset value so as to switch the river water source in the river water source main inlet pipeline to the tap water source. The objective of reducing adverse influence on community residents caused by the water quality factor in the process of using a multi-water-source water supply system of users can be realized by the application.

Description

Technical field [0001] The invention relates to the technical field of water supply with multiple water sources, in particular to a device and method for flexible switching of multiple water sources in a community based on water quality conditions. Background technique [0002] At present, with the gradual development of community construction, in order to comprehensively utilize various water resources, some high-end communities have gradually adopted a multi-source water supply system to replace the original single-source water supply. The so-called multi-source water supply system usually includes a reclaimed water supply system, a direct drinking water supply system, a heat medium water supply system and a tap water supply system. Among them, the reclaimed water supplied in the reclaimed water supply system can be used to flush the toilet, the direct drinking water supplied by the direct drinking water supply system can be directly drinkable, the heat medium water supplied by...

AI Technical Summary

Problems solved by technology

[0003] Although people have different water quality requirements for each type of water supply in a multi-source water supply system, people have minimum requirements for each type of water supply quality. psychological needs

For example, the reclaimed water supplied in the reclaimed water supply system can be used to flush toilets. People have relatively low requirements for its water quality. However, once there is a problem with the daily treatment process of the reclaimed water plant, it will lead to toxic substances such as bacteria and heavy metal ions in the reclaimed water output. When there are many, it is obviously difficult to meet the minimum requirements of the residents for the quality of reclaimed water

In the current real life, once the water quality of a certain water source deteriorates, the residents have no choice but to continue to use these problematic water sources, which will cause serious adverse effects on the daily life of the residents.
