Study on Wastewater Treatment Technology and Water Environment Protection Method

Abstract

Abstract Water resources are very important for human beings, and water resources are indispensable for normal life and industrial production. With the population growth and industrialization in China, the shortage and pollution of water resources are becoming more and more serious, which not only restricts the further development of our society, but also has a serious impact on people’s lives. Emulsions are widely used in metal processing. Waste emulsions are hazardous wastes, which can cause serious harm to the ecological environment and need to be properly treated. The results show that the oil removal rate of different emulsion wastewater is over 85%, and the COD removal rate is between 36-97%. It shows that the vibrating membrane has good performance of preventing membrane fouling and concentration polarization. In this situation, only by strengthening the treatment of wastewater and focusing on the protection of water environment can we achieve sustainable development and promote the harmonious coexistence between man and nature.
