Clarification of High-Salinity Mine Water with Plants

Abstract:

High-salinity mine water has been often treating with electrodialysis, multi-effect. But there are still some problems. So we study high-salinity mine water treatment for 24 days with different plants and salinity. The sample was selected from Zhang Xiao Lou coal in Xuzhou. The resultes show that: Cress is able to adapt the water with high salinity and absorb the contamination. When the dosage of NaCl is 1 g/L and 2 g/L, TDS removal efficiency can reach 69.36% and 56.47%. With the increase of NaCl from 0 to 1 g/L, the treatment capacity of the plant increased gradually, and the treatment capacity would decline if the dosage sustained increase. TDS removal efficiency was best, when the dosage of NaCl is 1 g/L, respectively: 56.47%, 50.21% and 44.00% with different plants, and the plants also has a good effect on the removal of COD and nutrient element when the dosage of NaCl is 1 g/L.
