introduction After the reform and opening up, my country's economic level has been greatly improved, but it is opposite to the increasingly serious environmental problems, among which the water environment problem has attracted the attention of most people. At present, the prevention and control of water environment pollution mainly adopts membrane technology. Compared with traditional water purification technology, membrane technology has higher efficiency, stronger practicability and better effect in the in-depth treatment of water quality. Membrane technology has a good development prospect in the field of water purification, so a sufficient understanding of the technology should be carried out. The importance of the application of membrane technology in the field of water purification is discussed, and its development trend is discussed.
In recent years, with the rapid development of my country's industry, industrial water consumption has also increased, so industrial wastewater is also increasing year by year. Among them, the increase in the amount of wastewater in the pharmaceutical and chemical industry is particularly obvious. During this process, pharmaceutical and chemical wastewater also gradually showed the characteristics of difficult degradation, high salinity and complex composition, coupled with the continuous development of production technology. The difficulty of wastewater treatment is greatly increased, which poses a great threat to our country's environment.
