摘要:
污水处理工艺的比选对污水处理效率和运营成本至关重要。分段进水多级A/O工艺作为活性污泥法的一种，具有高效脱氮和节省成本的优点；MBR工艺同样具有高效的处理效率和节地的优势，但其高能耗的缺点较突出。针对北方某城市同一区域的A、B两座污水厂，从处理水量、水质、能耗和成本等方面进行分析，以期为同地区污水处理质量和付费监管以及新建污水处理厂工艺比选提供借鉴。对比分析可知，分段进水多级A/O工艺只需在进水TN冲击的工况下投加外碳源，相比MBR在全年超设计规模21.5% 水量工况运行下其电耗节省0.1 kW·h/m3。另外，MBR的次氯酸钠消耗较大，平均单耗比多级A/O工艺高出35 mg/L。经计算，多级A/O工艺的运营生产成本约0.495元/m3，MBR工艺的运营生产成本约0.955元/m3。
Abstract:
The comparison and selection of sewage treatment processes is very important to the efficiency and operating cost of sewage treatment. As one of the activated sludge processes, the step-feed multi-stage A/O process has the advantages of efficient nitrogen removal and cost saving. The MBR process also has the advantages of high treatment efficiency and land saving, but its disadvantage of high energy consumption is more prominent. This paper analyzes the treated water quantity, water quality, energy consumption and cost of two water plants in the same area of a city in the North China, so as sto provide reference for regional sewage treatment quality and payment supervision, and process selection of the new WWTP. The comparative analysis shows that the step-feed multi-stage A/O process only needs to add the external carbon source under the condition of influent TN impact. Compared with MBR under the condition of annual water volume exceeding the design scale by 21.5%, the power consumption of multi?stage A/O process is saved by 0.1 kW·h/m3. In addition, the sodium hypochlorite consumption of MBR is increased, and the average single consumption is 35 mg/L higher than that of the multi-stage A/O process. Through calculation, the operating production cost of multi-stage A/O process is about 0.495 yuan/m3, and the operating production cost of MBR process is about 0.955 yuan/m3.
