摘要:
针对榨菜废水尾水高盐度、高氮磷污染物的特点，以及现有处理技术存在的问题，对比研究了生物膜法、固定化小球藻以及藻菌共生系统对榨菜废水尾水的处理效能。对于有机物，生物膜法的处理效果最佳，藻菌共生系统次之，COD去除率分别为92.18%、83.10%；固定化小球藻的处理效果最差，出水COD浓度比进水增加了78.44%。对于氮、磷污染物，藻菌共生系统的处理效果最好，NH4+-N、TN和PO43--P去除率都达到了100%；固定化小球藻的处理效果次之，NH4+-N、TN和PO43--P去除率分别为100%、99.95%、96.70%；生物膜法的处理效果最差，NH4+-N、TN和PO43--P去除率分别为48.06%、62.80%、10.69%。可见，藻菌共生系统既具有生物膜法高效去除有机物的优点，又具有固定化小球藻高效脱氮除磷的优点，为榨菜废水尾水处理提供了一种高效可行的方法。
Abstract:
Targeting the high salinity, nitrogen, and phosphorus pollutants present in the tailwater from mustard tuber wastewater treatment plants, as well as the challenges associated with existing treatment technologies, this study aimed to investigate the treatment efficiency of biofilm process, immobilized Chlorella, and microalgae-bacteria symbiotic system on the tailwater from a mustard tuber wastewater treatment plant. The biofilm process demonstrated the most effective treatment for organic matter, with COD removal rate of 92.18%, followed by the microalgae-bacteria symbiotic system at 83.10%. Conversely, the immobilized Chlorella exhibited the least favorable treatment efficiency, resulting in a significant increase of 78.44% in effluent COD. In terms of nitrogen and phosphorus pollutants, the microalgae-bacteria symbiotic system proved to be highly effective, achieving 100% removal rate for NH4+-N, TN, and PO43--P. The second treatment performance of immobilized Chlorella was observed, with NH4+-N, TN, and PO43--P removal rates of 100%, 99.95% and 96.70%, respectively. The treatment performance of biofilm process was the worst, with removal rates of NH4+-N, TN, and PO43--P at 48.06%, 62.80%, and 10.69% respectively. It was evident that the microalgae-bacteria symbiotic system not only offered the advantages of the biofilm process for efficient removal of organic matter, but also provided the benefits of immobilized Chlorella for effective elimination of nitrogen and phosphorus. This presented an efficient and viable approach for treating tailwater from mustard tuber wastewater treatment plants.
