Expansion of the basic definition of unconventional water sources;

Unconventional water sources are different from traditional water resources (surface water and groundwater), mainly including rainwater, reclaimed water, desalinated seawater, mine water and brackish water. Their characteristics are that they can be used or recycled after treatment, and can replace conventional water resources to some extent. The characteristic of these water sources is that they can be recycled after treatment.

The significance of expanding the use of unconventional water sources;

1 can replace conventional water resources to some extent, accelerate and improve the circulation process of natural water resources, and make limited water resources play a greater role.

2. By increasing the use of unconventional water sources, the use of surface water and groundwater can be reduced. Taking mine drainage as an example, this part of wastewater can be used as production, living and ecological water after treatment. After meeting the enterprise's own needs, the rest will be connected to the government's comprehensive utilization pipe network after reaching the standard. According to the overall allocation mode of water resources, combined with the regional water demand object and current situation, it can be used in different regions.

3. It can effectively promote the protection and recycling of regional water resources, effectively alleviate the shortage of water resources, promote the development of circular economy, and improve and protect the water ecology and environment.
