| Abstract: | It is investigated that the waste black liquid in soda paper-making is compre-hensively treated by four aggregating agents which are commerical sulfuric acid,wasted nitration liquid,poly-aluminium chloride made in present work andaluminium sulfate.Adding a suitable amount of the agents,the suspension solidparticle,disolved organic acid and lignin in the black liquid are aggregated.Thedecolor ratio is up to 98%.The filtrate conforms to the national discharge stand-ard.The residual has been made to nitrocellulose for producing smokeless powder. |
