Abstract:The article introduces the pollution status of chromium-contaminated site and the harm of chromium pollution.Then the article discusses the research status of restoration technologies,including stable curing technology,chemical reduction technology,soil washing technology,electrochemical remediation technology and bioremediation technology.In addition,the article looks into the development tendency of governing the chromium-contaminated site.Bioremediation has its distinguished advantages in terms of non secondary contamination and electrochemical remediation possesses the high efficiency in mass transfer.Therefore,the combination of the two technologies may achieve the better effect.

Key words:chromium;contamination;restoration;soil
