| Abstract: | A new technology of chrome tanning liquid waste treated and utilized was studied. The results showed that efficiency of separating impurity might be up to 80 %, and purity of reclamating chromic might arrive at requirements for tannage technology. The optimum conditions are that sodium hydroxide and lime are used as precipitant, pH volue is controlled within 8.5-9.0,hydrolytic decomposition time is 2h, and cleaning with hot water twice within two hours. |
