Abstract In this study, a pilot-scale subsurface wastewater infiltration system (SWIS) was deployed to study landscape water treatment. The goal of the study was to investigate the effects of hydraulic loading on pollutant removal and the spatial distribution of biofilm properties in SWIS. Results showed that the efficiencies of chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) removal degraded as hydraulic loading increased. Furthermore, quantities of the biofilm properties parameter s increased with the hydraulic loading. Polysaccharide and protein levels ranged from 560 to 1110 μg/g filler and 60 to 190 μg/g filler, respectively, at a hydraulic loading of 0.2 m/d. At a hydraulic loading of 0.4 m/d, the quantities of polysaccharide and protein ranged from 1200 to 3300 μg/g filler and 80 to 290 μg/g filler, respectively. Biofilm intensity and biofilm activity per unit weight decreased with the increase in hydraulic loading.

水力载荷对地下水渗滤系统生物膜特性的影响

摘要 在这项研究中，部署了一个中试规模的地下污水渗透系统 (SWIS) 来研究景观水处理。该研究的目的是研究水力载荷对 SWIS 中污染物去除和生物膜特性空间分布的影响。结果表明，化学需氧量（COD）、总氮（TN）和总磷（TP）的去除效率随着水力负荷的增加而降低。此外，生物膜特性参数 s 的数量随着液压载荷的增加而增加。多糖和蛋白质水平分别为 560 至 1110 μg/g 填料和 60 至 190 μg/g 填料，液压载荷为 0.2 m/d。在 0.4 m/d 的水力载荷下，多糖和蛋白质的量分别为 1200 至 3300 μg/g 填料和 80 至 290 μg/g 填料。
