摘要:
污水处理作为全球十大温室气体排放行业之一，如何实现协同减污降碳成为推动我国低碳减排进程的重要课题。采用活性污泥动力学模型结合城镇污水系统厂级碳核算方法，以南方城市某污水处理厂为例，给出了在水质达标条件下实现节能降耗和减少碳排放量的协同方法。利用BioWin软件建立某污水处理厂工艺模型，出水COD、NH3-N、TN和TP模拟结果与实测数据误差较小。当好氧池到缺氧池的回流比为225%、MBR池到好氧池的回流比为200%、好氧池DO浓度为2 mg/L时，可降低出水NH3-N和TP浓度，并降低运行能耗，预计节约电费30.75万元/a。同时，优化工艺条件后预计可减少年碳排放量405.73 t （以CO2计），反哺实现厂界范围内综合碳减排3.5%，且污染物削减碳排放强度降低。在双碳目标约束下，城镇污水处理厂宜采用数学模拟技术探寻最佳工况条件，平衡出水水质和能耗药耗成本，实现减污降碳协同增效。
Abstract:
As one of the top ten CO2 emission industries in the world, how to achieve collaborative reduction of pollution and carbon emissions of the wastewater treatment plants has become an important topic to promote low-carbon emission reduction process in China. In this study, the activated sludge dynamic model combined with the factory-level carbon accounting method of urban sewage system was used, and a wastewater treatment plant (WWTP) in southern city was taken as an example to analyze how to achieve energy saving and carbon emission reduction under the condition that the water quality meets the standard. The results showed that the process model of a WWTP was established by using BioWin software, and the error between the simulated results of effluent COD, NH3-N, TN and TP and the measured results was small. When the reflux ratio from the aerobic tank to the anoxic tank was 225%, the reflux ratio from the MBR tank to the aerobic tank was 200%, and the dissolved oxygen concentration in the aerobic tank was 2 mg/L, the effluent concentrations of ammonia nitrogen and TP could be decreased, and the energy consumption could be reduced, which was estimated that the electricity cost would be saved by 307 500 yuan per year. At the same time, the optimized process conditions were expected to reduce the annual carbon emissions of 405.73 t CO2, and achieved a comprehensive carbon emission reduction of 3.5% within the plant boundary，and pollutant reduction carbon emission intensity was reduced. To achieve the goal of carbon peak and carbon neutralization, the mathematical simulation technology should be adopted in WWTPs to explore the best working conditions, balance the effluent quality and energy and drug consumption costs, and provide technical support for realizing the synergistic effect of pollution reduction and carbon reduction in wastewater treatment plants.
