| Abstract: |
| Bentoniteh is modified by macromolecular flocculant PDMDAAC,The simulation experiment on the treatment for dyeing wastewater with modified bentonite is conducted by the orthogonal experiment method.The result shows that the efficiency of bentonite modified by PDMDAAC for color removal of wastewater is greater than bentonite and activated carbon.The discoloring rate can reach up to 97.8% under the given optimal conditions.This technology has advantages of good treatment efficiency and easy operation. |
