| Abstract: | In order to explore the differences of the effects of different chemical treatments on the waste water from cooking wood, we have taken two kinds of woods for cooking tests. The test results show: there are differences in the release of the lignin in the woods; under the circumstance of the extent of the concentration of alkali lower than 1%, the woods cn release more lignin when more alkali is put into the cooking water; the coagulation treatment si better than acid-out one to remove the COD_(Cr) and the lignin. Using the former treatment, 70% of lignin in the waste water can be discomposed if FeCl_3 is added in it. |
