| Abstract: | The application of complex reagents consisting of activity transforming agent, highly active dispersant,flocculant Ⅱ to pretreat waste water from 1.2Mt/a delayed eoking device was studied. The results showed that the average removing rate of COD,organic substance, suspended substance and sulfide in waste water was able to reach 99. 3% ,99. 9% ,86. 8%, 76. 8% respectively after the use of complex reagents, which can ensure the stable operation and discharge standard of the sewage treatment workshop. |
