摘要:在“碳達峰、碳中和”的政策驅動下，為優(yōu)化脫水工藝實現(xiàn)節(jié)能減排，2022年北排清河第二再生水廠污泥處理中心通過對濃縮機、預脫水機、板框壓濾機三個生產(chǎn)區(qū)域的設備處理量、運行數(shù)量和臺時進行調(diào)控，實現(xiàn)了脫水區(qū)域電單耗的顯著降低。通過提升濃縮機的進泥負荷、減少設備開機頻次，該區(qū)域電單耗下降17.52 kW·h/tDS；通過優(yōu)化預脫水機開機頻次和螺旋輸送機運行，該區(qū)域電單耗下降3.48 kW·h/tDS；通過對板框區(qū)域采取分區(qū)運行、低壓進泥泵低頻率運行、無進料回流運行等措施，該區(qū)域電單耗同比下降約51.89 kW·h/tDS。采取以上工藝調(diào)控措施后，2022年脫水區(qū)域總電單耗為324.39 kW·h/tDS，較2021年下降17.9%，節(jié)電對應CO2減排量約1 440.09 t。
Abstract:Driven by the policy of “carbon peak and carbon neutrality”, in order to optimize the energy saving and emission reduction of dewatering process, the sludge treatment center of Qinghe Ⅱ reclaimed water plant of Beijing Drainage Group realized significantly reduction of unit power consumption in the dewatering area in 2022 by regulating the equipment treatment capacity, equipment operation quantity and unit hours in the three production areas of thickener, pre-dehydrator and plate and frame filter press. By increasing the sludge load of thickener and reducing the frequency of equipment start-up, the unit power consumption in this area decreased by 17.52 kW·h/tDS. By optimizing the start-up frequency of the pre-dehydrator and the operation of the screw conveyor, the unit power consumption in this area decreased by 3.48 kW·h/tDS. The unit power consumption in the plate and frame area decreased by 51.89 kW·h/tDS year on year by taking measures such as zoning operation, low frequency operation of low pressure sludge pump and no feed reflux operation. Through the above process control measures, the total unit power consumption in the dewatering area have decreased to 324.39 kW·h/tDS in 2022, 17.9% lower than that in 2021, and the power saving corresponds to about 1 440.09 t of CO2 emission reduction.
