Solidification/stabilization (S/S) is one of the commonly used physicochemical remediation technologies of contaminated soil, with a wide range of application prospects in the site remediation in China due to its advantages of being inexpensive, nontoxic and good comprehensive effect. This paper introduced the basic principles and materials of S/S technology, and analysed its application scope, merits and drawbacks. Reported cases of S/S remediation on heavy metals and organic pollutants were summarized in the present study. Based on the actual demand of soil remediation in China, the strategies for optimizing the S/S remedial technology were proposed: Promoting the research on engineering technology and equipment; lowering the cost of remediation; developing environment-friendly S/S remediation technologies.
