| Abstract: | Silicon in the black liquor was Firstly removed by-coagulation and centrifugation and lignin was separated from the black liquor with acidification-precipietion, The study also focused on the removal of COD of the lignia free black liquor by coagulation and catalytic oxidation. Experimental results indicate that the technique mentioned above can effectively treat straw pulp effluent-black liquor. COD Value of tie treated water can be less than 300mg/L and lignin can be recovered as by-product. |
