- Abstract:
- The MBR process of Kunming No.4 wastewater treatment plant (WWTP) has been in operation for more than ten years. Considering the membrane depreciation cost, the total operation cost within membrane life cycle is about 0.68 yuan/m3. The electricity and membrane maintenance costs increase as flux decays mainly cause the increasement of total operation costs. The occupied area, effluent quality, reclaimed water utilization, equipment operation, as well as replacement and use of different types of membranes are analyzed. It concludes that the economical utilization of land resources and reclaimed water as well as the reduction of membrane cost can greatly reduce the overall investment cost of MBR. From the perspective of operation management, MBR process effluent stability, equipment operation and membrane maintenance are not too complicated and have strong adaptation.
