Remediation Technology and Practice of Heavy Metal Polluted Soil

China has always attached great importance to economic development, and the economic level is rapidly improving. However, in this process, there is a lack of attention to the ecological environment. Many enterprises and factories discharge untreated or simply treated heavy metal pollutants into the soil during production and operation, causing serious impacts on human health and the ecological environment. With the continuous development of the times, China has gradually realized the importance of environmental protection. With the continuous innovation and development of biotechnology, chemical technology, and physical technology, many new technologies for heavy metal contaminated soil remediation have emerged. These technologies have been continuously applied and improved in practice, hoping to effectively solve the problem of heavy metal pollution. This article will review the current common remediation technologies for heavy metal contaminated soil, evaluate and analyze them, aiming to provide reference and reference for solving the problem of heavy metal contaminated soil remediation.
