| Abstract: | The simulation experiment on the treatment for chromium containing wastewater by fly ash absorption is conducted. The remit show that the removal rate of Cr can be over 98 % with pH value 2.00 - 3.74, the dosage of fly ash 2 g and the contacting time 80 mins; the absorption accords with Freundlich absorption isotherms, the equation of absorption is logq =1.5689 - 0. 1464logc, mainly with physical absorption; and the volume of penetration is 90 mL. This technology has advantages of good treatment efficiency, easy operation, low running expenses, and so on. |
