| Abstract:The faced challenges of traditional process of anaerobic-aerobic-depth treatment of chemical-mechanical pulp wastewater in stable operation were analyzed in this paper， as well as the problems that existed in the application of the zero-discharge process for chemical-mechanical pulp high concentration wastewater. An economic treatment process of high concentration wastewater from chemical-mechanical pulp was proposed， and the considerations and benefits in process practice were summarized.The results showed that the company could save 11.47 million yuan/a after the high concentration wastewater from chemieal-mechanical pulp treated by economie treatenent process. |
