Phytoremediation as a sustainable tool to rehabilitate land contaminated by high‑density sludge sediment: from waste to green
Aims
The HDS sediment produced in the treatment of mine wastewater by HDS process (high-density sludge method) has become a difficult problem in the disposal of mine solid waste due to its large storage and low comprehensive utilization rate. This study aimed to explore the effect of phytoremediation method on the ecological restoration of HDS sediment dump.
Methods
A 5-year field investigation was conducted to examine the effect of revegetating a HDS sediment dump with eight woody plant species, i.e., Ligustrum lucidum L., Ligustrum quihoui L., Robinia pseudoacacia L., Rhus chinensis L., Salix hybrid L., Hibiscus mutabilis L., Nerium indicum L., Hibiscus syriacus L., on the physicochemical properties, nutrients, enzyme activities, microbial activities and heavy metal contents of the HDS sediment.
Results
The results showed that revegetation significantly improved the physicochemical properties (pH, electrical conductivity, water content, redox potential), nutrients (N, P, K, organic matter), enzyme activities (phosphatase, invertase, urease), microbiological composition and respiration (bacteria, fungi, actinomyces, microbial biomass, respiration intensity) of the HDS sediment. Compared with the control (bare sediment without revegetation), revegetation reduced the contents of Cd, Cu in the sediment. In addition, the contents of DTPA-Cd and DTPA-Cu in the sediment showed a decreasing trend.
Conclusions
Furthermore, as discovered from the PCA analysis results, R. pseudoacacia has greater restoration potential for copper sulfide acidic wastewater sludge, which was suitable for primary woody plants to repair the HDS sediment dump.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
