Research and application of integrated water pollution prevention and control technology in expressway construction

Abstract

In view of water environmental protection requirements during construction of the Lin'an-Jiande Section project of the Zhejiang Lin'an-Jinhua Expressway, field investigation and test analysis are adopted to determine the pollution link in the project construction process, put forward the special measures for construction wastewater treatment of roadbed, bridge, tunnel, and precast mixing station, form an integrated prevention and control technology system for water environmental pollution in expressway construction, and effectively guarantee the water environmental safety of project construction. China has continued to make efforts in pollution prevention and control in recent years, with the goal of achieving clear water, blue sky, and pure land, as well as improving overall ecological and environmental protection. A wide range of technology research and application is carried out for water pollution prevention and control during the construction of the Zhejiang Expressway construction project. By establishing a sound system for prevention and control measures (JTJ 1997), effective technologies for water pollution prevention and control are implemented to improve environmental protection in the expressway area. This paper focuses on the Lin'an-Jiande Section project of the Zhejiang Lin'an-Jinhua Expressway. It conducts the investigation and analysis of water pollution sources in expressway construction, puts forward the water pollution prevention and control measures against each pollution link, sets up an integrated prevention and control system, and adopts various physical and chemical treatment processes for purification and disposal of the polluted water, thus effectively ensuring the water pollution prevention and control in expressway construction.
