重金属污染土壤淋洗废水处理的研究进展

A Review on Effluent Disposal in Heavy Metals Contaminated Soil Washing

重金属污染土壤淋洗废水的主要成分是过量淋洗剂和重金属与土壤淋洗剂的络合物,从以废治污角度出发,如何将淋洗废水还原为淋洗剂成为了关键技术难点。本文综述了各种适宜淋洗废水处理的技术,讨论了其技术特点、优势及其局限性,同时总结出一套可行性较高的处理措施,并展望了淋洗废水未来的处理方向,旨在为研究重金属污染土壤淋洗废水处理技术提供理论依据。

The main component of heavy metal contaminated soil leaching waste water is excess eluent and complexes which obtained by reacting eluent with heavy metals. It is that how to restore the soil leaching wastewater to eluent become the key technical difficulties. This paper reviews the various technologies which appropriately processes soil leaching wastewater, and discuss its technical features, advantages and limitations, and summed up a set of process with high feasibility. At last looked to the future direction of the leaching process wastewater, and purposed to provide a theoretical basis for heavy metal contaminated soil leaching waste water treatment technology.
