jailcd2020099: Development Status and Trend of Water Treatment Membrane Technology

Abstract

Due to the rapid development of the city and the continuous improvement of people's living standards, it not only brings opportunities, but also challenges the urban construction, and puts forward higher requirements for the urban environment. China is a country with a large population and a vast area. Due to the geographical reasons, the distribution of water resources is seriously uneven. In addition, in recent years, the environmental pollution problem is becoming increasingly serious, which makes China's water resources scarcer. The prevention and control of water pollution becomes very important. Therefore, the treatment and recovery of sewage has also been widely concerned. Membrane treatment technology has high efficiency in sewage treatment, plays an important role in sewage treatment, and lays a foundation for the development of the city. Compared with the traditional sewage treatment method, it has more advantages. Therefore, at present, the technology is mostly used for sewage treatment. In this paper, the development status of water treatment membrane technology is briefly introduced, and the development trend of water treatment membrane technology is put forward. The innovation and development of membrane technology mainly include the improvement of membrane performance, the development of membrane material and manufacturing process, land the improvement of membrane application technology.
