摘要/Abstract

摘要：

针对石英砂（OQS）表面特征及特性，进行表面形貌重构改性及表面涂覆改性，并根据涂覆改性差异，制备出亲水改性砂（IMS）、疏水改性砂（OMS）、阳离子改性砂（CMS）和氨基改性砂（AMS）。以实验室模拟二级处理出水为研究对象，考察以6种石英砂[4种复合改性砂、表面重构砂（对照1）及原始砂（对照2）]为核心的生物砂滤工艺对碳氮磷及突发药物活性物质（PhACs）的削减效果，分析了各组生物砂滤池微生物种群结构，并进行了生态风险评估。结果表明，各类工艺对常规污染物的去除率在24.22%~90.35%之间，CM-BSF对常规污染物的去除效果最好；6种生物砂滤工艺对5大类12种PhACs的去除率在7.9%~50.3%之间，改性砂滤工艺CM-BSF去除效果更好；高通量检测表明各组微生物物种高度相似，但丰度有差异，总体来说，具备PhACs降解能力的功能菌在复合改性石英砂覆膜生物样品中的丰度较高；通过生态风险评价方法分析，CM-BSF工艺出水产生生态风险最小。

Abstract:

Aiming at the surface characteristics and properties of quartz sand (OQS), surface morphology reconstruction and surface coating modification were performed. According to the coating modification difference, hydrophilic modified sand (IMS), hydrophobic modified sand (OMS), cationic modified sand (CMS) and amino modified sand (AMS) were prepared. The laboratory simulated secondary treatment effluent was taken as the research object, and the biological sand filtration process centering on 6 kinds of quartz sand [4 kinds of composite modified sand, surface reconstituted sand (control 1), and original sand (control 2)] was investigated. The reduction effect of carbon, nitrogen, phosphorus and sudden pharmacologically active substances (PhACs), the microbial population structure of each group of bio-sand filters was analyzed, and ecological risk assessment was performed. The results show that the removal rate of conventional pollutants by various processes is between 24.22%—90.35%, and the removal effect of CM-BSF on conventional pollutants is the best; 6 types of biological sand filtration processes remove 12 types in 5 categories of PhACs. The rate is between 7.9%—50.3%, and the removal effect of CM-BSF by modified sand filtration process is better. High-throughput testing shows that the microbial species in each group are highly similar, but the abundance is different. Generally speaking, it has PhACs degradation ability. The abundance of the functional bacteria in the composite modified quartz sand-covered biological samples is relatively high. According to the analysis of the ecological risk assessment method, the ecological risk of effluent from the CM-BSF process is the lowest.
