| Abstract: | According to the local conditions and the comparison between different proposals,the reclaiming of rough lignin by acid settlement and the reuse of processed lignin are adopted as the most economically effcient project to treat the black liquor pollution.A primary estimate shows that a recovery of 1000 kg of rough lignin will bring 100 renminbi yuan of net income to the enterprise,not including the economic benefits from the usage of the processed lignin.The relevant technology is based on the production and experiments,so it is completely feasible. |
