Research progress of phytoremediation combination technology to remediate heavy metal contaminated soil

Phytoremediation of heavy metal contaminated soil is a new treatment technology for soil pollution developed in recent years, due to the low cost and small environmental perturbations. For complex environments, however,phytoremediation of the single usually seems so weak, therefore it needs phytoremediation to improve the efficiency of remediation, reduce remediation cost. According to the existing research, this article briefly discussed the single phytoremediation of soil contaminated by heavy metals, focused on the research progress using phytoremediation combination technology in terms of heavy metals soil contaminated in recent years, in the mean time, the view also gave a prospection on the future research of the domain.
