| Abstract: | The distribution of sulphuric acid under the situation of using recycle acid and no using recycle acid in the proess of activated carclazyte production was expounded.The utilization ratio of sulphuric acid was less than 20%,the surplus acid were presented in the acidic waste water.The chemical compositions of various acidic waste waters were listed to provide scientific basis for the improvement of the production process of activated carclazyte,neutral treatment of acidic waste waters and its further comprehensive utilization. |
