低溶解氧MBR工艺脱氮除磷效率及碳排放特征研究OACSTPCD
Research on Nitrogen and Phosphorus Removal Efficiency and Carbon Emission Characteristics of MBR Process with Low DO Condition
为强化脱氮除磷效率,推动污水处理绿色低碳发展,基于W污水处理厂,研究了降低膜生物反应器(Mem-brane Bio-Reactor,MBR)处理生活污水能耗及碳排放强度的路径,分析了低溶解氧对脱氮除磷的影响,结合微生物特性进行了机理分析,同时核算了碳排放强度.结果表明,动态调整好氧区溶解氧浓度,保持溶解氧浓度在0.5 mg/L左右,同步调整回流比,出水能够稳定达到四川省地标,TN、TP去除效率提升10％、8％,其主要原因是低溶解氧条件下厌氧区OR…查看全部>>
To enhance the efficiency of nitrogen and phosphorus removal and promote the green and low-carbon development,based on the W wastewater treatment plant,the path to reduce the energy consumption and carbon emission intensity of membrane bioreactor(MBR)treatment of domestic wastewater was studied,and the impact of low dissolved oxygen on nitrogen and phosphorus removal was analyzed.The mechanism analysis was conducted in combination with microbial characterist…查看全部>>
