Cultivated land soil pollution has seriously affected food security and people's living and health level in our country. Therefore, this study discusses how to use engineering technology to restore polluted land into utilizable land. The author analyzed the present situation of soil pollution development in China by summarizing the domestic and foreign literatures on the treatment of polluted land. Based on the engineering and technical experience of polluted land control and restoration for many years, this paper discusses the engineering and technical points of polluted land physical restoration, and how to use physical measures to transform polluted land into utilizable land, and looks forward to the development trend of polluted land restoration in China. This study lays a theoretical foundation for proposing soil pollution remediation technology suitable for China's national conditions and regional characteristics, and provides technical support for national food security and ecological civilization construction.
