Abstract：In order to research the saline-alkali soil ameliorating status and species changes of chromium during comprehensive utilization of chromium-contented acid wastewater with saline-alkali soil, permeation and pressure equipments are adopted to simulate the process of chromium-contented acid wastewater permeating through different pH saline-alkali soils. By the assaying and analyzing some indicators of pH, ORP, ESP, sum of Ca2+ and Mg2+, organic matter, and the different factions of Cr, test results show that the course of chromium-contented acid wastewater permeating through saline-alkali soil makes saline-alkali soil tend to be neutral. And it would not reduce soils autologous organic matter and the levels of Calcium and Magnesium. The overall migratory capacity of Cr in the acid waste water is weak. It states that the saline-alkali soil has an obvious effect on the chromium-contented acid wastewater treatment, and the saline-alkali soil is also ameliorated.
