Design Case of Sludge Disposal in Strong Flavor Liquor WWTP
To investigate an appropriate disposal process in the strong flavor liquor wastewater treatment plant(WWTP)sludge,fulfilling the requirements of energy conservation,carbon reduction,and efficient energy utilization,a proposal is made to compare the design concepts of mainstream sludge disposal processes through energy consumption analysis.The results show that the centrifugal dewatering and low-temperature sludge drying processes do not require the consumption of biogas and additional supplementary energy.They satisfy the requirements for energy utilization and are suitable for use in the sludge disposal of strong flavor liquor WWTPs.Through investment analysis,the proposed scheme incurs a cost of 128 million yuan over ten years,while the frame dehydrator scheme costs 156 million yuan over the same period,possessing a cost advantage.The case has a certain reference and reference significance for the design of sludge disposal in strong flavor liquor WWTPs.
