The concept of "zero discharge" refers to the high degree of purification of industrial wastewater after a series of treatment processes, so that the final discharge of wastewater is reduced to a very low level (usually more than 99%), and even no waste liquid is discharged to the external environment. In this process, the salts and pollutants in the wastewater are efficiently recovered or converted into solid form, and then disposed by landfill or resource utilization, so as to realize the recycling of wastewater and minimize the discharge of pollutants.

In the process of achieving "zero discharge" of wastewater, the effective treatment and resource utilization of salt-containing wastewater has become the key. With the help of advanced treatment technology, high salt components in wastewater can be effectively removed, and useful substances in it can be recovered, and finally achieve "zero discharge" of wastewater.
