摘要

摘要:
随着乡村振兴战略的深入推进和污水排放标准的日趋严格，对农村生活污水处理技术提出了更高要求。针对移动式生物膜技术进行优化改进，构建了组合式上向分流多介质生物膜工艺，以实际农村生活污水为处理对象，探究该技术处理效果及推广应用价值。结果表明，该工艺可高效利用污水中的碳源进行脱氮，在多介质膜池水力停留时间≥0.15 d、气水比≥3∶1及1.50倍硝化液回流条件下，实现无污泥回流条件下对污水中的悬浮物、总氮、氨氮、化学需氧量和总磷的去除，去除率分别达96.23%、47.33%、78.89%、79.38%和80.77%，出水水质优于GB 18918—2002《城镇污水处理厂污染物排放标准》的一级A标准。

Abstract:
With the in-depth advancement of the rural revitalization strategy and the increasingly stringent sewage discharge standards, higher requirements have been placed on rural domestic sewage treatment technology. The mobile biofilm technology was optimized and improved when an upward-shunting multi-media biofilm operation system was developed. The treatment effect of the technology for actual rural domestic sewage was investigated, and its promotion and application value was discussed. The results indicated that the carbon source in the sewage system was utilized efficiently for denitrification. With the experimental conditions of hydraulic retention time longer than 0.15 d, the gas-to-water ratio greater than 3:1 and 1.50 times of nitrification liquid reflux ratio simultaneously, the removal rate of SS, TN, NH₄ ⁺-N, COD_Cr and TP in sewage reached 96.23%, 47.33%, 78.89%, 79.38% and 80.77%, respectively, without sludge return. Besides, the effluent quality was better than Level 1 A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
