| Abstract: | The rectorite is modified by sulfate and the macromolecular flocculant Poly-dimethyl-diallyl-ammonium chloride. The simulation experiment on the treatment for wastewater containing cyanide with modified rectorite absorption is conducted. The results show that the removal rate of cyanide can be 99% with pH is 4.5, the dosage of modified bentonite is 2.5g/L and the contacting time is 75 min, the reaction temperature is 25 ℃. The absorption accords with Langmuir absorption isotherms. This technology has advantages of good treatment efficiency, easy operation, and so on. |
