Brief Analysis of Urban Sewage Treatment Technology and Its Practical Application in Environmental Engineering

With the continuous progress of China's economy, China's various industries are also in the rapid development and progress, at the same time, the impact on China's environment is also huge, especially under the current social and industrial chaos layout, want to improve the development speed of China's economy, it is necessary to manage the urban environment. And now the emergence of large areas of sewage wastewater, automobile exhaust and other exhaust gas caused the current serious damage to the ecological environment, a variety of natural disasters to occur constantly, which also let people appreciate the necessity of protecting the environment. In environmental engineering, the management of sewage and wastewater discharge is also the most important part of it. The sewage and wastewater in cities mainly come from the sewage produced in factories and that produced in daily life. In the era of scientific and technological progress, the treatment technology of sewage wastewater is also developing and improving. This paper mainly analyzes the application of traditional wastewater treatment technology and modern sewage treatment technology in environmental engineering according to the production causes of urban sewage and wastewater, so as to explore the way to improve the application efficiency of urban sewage treatment technology in environmental engineering.
