Currently, with the gradual development of community construction, some high-end communities gradually adopt a multi-water-source water supply system to replace the original single-water-source water supply in order to comprehensively utilize various water resources. So-called multi-source water supply systems generally include a reclaimed water supply system, a direct drinking water supply system, a hot water supply system, and a tap water supply system. Wherein, the reclaimed water supplied in the reclaimed water supply system can be used for flushing the closestool, the direct drinking water supplied by the direct drinking water supply system can be directly drunk, the heat medium water supplied by the heat medium water supply system is used for adjusting the indoor temperature, and the tap water supplied by the tap water supply system can be used as the domestic washing water and the like. The multi-water-source water supply system can achieve the purpose of maximizing the resource utilization by subdividing and utilizing water sources with different water qualities.
Although the water quality requirements of each supply water in a multi-water-source water supply system are different, the water quality of each supply water has the lowest requirement, and once the water quality is lower than the corresponding water quality requirement, the psychological needs of residents cannot be met. For example, the reclaimed water supplied in the reclaimed water supply system can be used for flushing a toilet, and the requirement of people on the quality of the reclaimed water is relatively low, but once the daily treatment flow of a reclaimed water plant has problems, and toxic substances such as germs, heavy metal ions and the like in the output reclaimed water are more, obviously, the minimum requirement of residents on the quality of the reclaimed water is difficult to achieve. In the current real life, once the water quality of a certain water source is deteriorated, the resident only needs to continuously select and use the water source with problems, and thus, the daily living life of the resident is seriously influenced.
In summary, it can be seen that how to reduce adverse effects on residential households due to water quality factors in a process of using a multi-water-source water supply system by users is a problem to be solved urgently at present.
