With the rapid development of industry, the types and quantities of wastewater are increasing rapidly, and the pollution of water body is becoming increasingly widespread and serious, threatening human health and safety. For environmental protection, the treatment of industrial wastewater is more important than that of urban sewage. Although the treatment of industrial wastewater began as early as the end of the 19th century, and a large number of experimental studies and production practices were carried out in the following half century, there are still some technical problems that have not been completely solved due to the complex composition and variable nature of many industrial wastewater. This is different from urban sewage treatment with mature technology.
In industry, concentrated water is generally considered to be the part removed when ordinary water becomes desalted water, that is, ordinary water=concentrated water+desalted water.
