| 摘 要： | 为进一步去除污水厂二级处理出水中的氮、磷和悬浮污染物,对比研究了一种新型生物膜-微絮凝滤池与高密度沉淀-纤维转盘过滤联用工艺(以下简称组合工艺)的深度处理性能。结果表明：新型生物膜-微絮凝过滤的出水TP质量浓度≤0.1 mg·L−1、$ {{rm{PO}}_4^{3 - }}$-P质量浓度≤0.05 mg·L−1、SS质量浓度≤10 mg·L−1、TN质量浓度≤2 mg·L−1、$ { {rm{NO}}_3^ - }$-N质量浓度≤0.5 mg·L−1;出水水质对受纳水体的环境影响小,综合污染指数仅为0.731,远小于组合工艺的2.734。此外,新型生物膜-微絮凝滤池避免了频繁的反冲洗,降低了反冲洗能耗,水处理成本仅为0.207元·m−3,比组合工艺低0.039元·m−3。

| Abstract: | To further remove nitrogen, phosphorus, and suspended pollutants from the secondary treated effluent of a wastewater plant, the depth treatment performances of a novel biofilm-micro flocculation and high-density sedimentation-fiber carousel filtration process (hereafter referred to as the combined process) were comparatively studied. The result shows that the water quality of new biofilm-micro flocculation filtered effluent was following: TP mass concentration ≤ 0.1 mg·L−1, $ {rm{PO}}_4^{3 - }$-P mass concentration ≤ 0.05 mg·L−1, SS mass concentration ≤ 10 mg·L−1, TN mass concentration ≤ 2 mg·L−1, $ {rm{NO}}_3^ - $-N mass concentration ≤ 0.5 mg·L−1. The environmental impact of the effluent water quality on the receiving water body was small, and the comprehensive pollution index was only 0.731 and was much smaller than 2.734 of the combined process. Besides, the new biofilm-micro flocculation filter avoids frequent backwashing, reduces backwashing energy consumption, and the cost of water treatment was only RMB 0.207·m−3, which was RMB 0.039·m−3 lower than the combined process. |
