摘要:
为了探究固相纤维素碳源（SCSC）和硫铁复合填料（S/Fe）耦合特性对再生水深度脱氮除磷的影响，根据进水流经先后顺序将其组合成SCSC-S/Fe和S/Fe-SCSC复合系统，在相同运行条件下分析两种系统对污染物的去除效果。结果表明，SCSC-S/Fe系统对TN、NO3--N和TP的平均去除率比S/Fe-SCSC复合系统分别高12.56、3.28和17.59个百分点。通过扫描电子显微镜（SEM）分析发现，SCSC-S/Fe系统中硫铁复合填料表面具有更多的球形反硝化细菌，硫铁复合填料沉积物的X射线衍射（XRD）图谱表明，出水中的PO43-主要以FePO4、Fe3（PO4）2（OH）2和Fe3（PO4）2·xH2O等形式被去除。SCSC-S/Fe系统中还出现了Fe6（OH）12CO3，这表明SCSC-S/Fe系统中异养反硝化、铁自养反硝化、硫自养反硝化、FeS自养反硝化和海绵铁脱氮作用协同效果更好，即固相纤维素碳源置于硫铁复合填料前端是其耦合的最佳方式。
Abstract:
In order to investigate the effect of the coupling characteristics of a solid-phase cellulose carbon source and a sulfur-iron composite filler on the advanced denitrification and phosphorus removal from reclaimed water, the SCSC-S/Fe composite system and the S/Fe-SCSC composite system were arranged according to the order of influent. The pollutant removal performance of the two composite systems was evaluated under the same operating conditions. The results showed that the average removal rates of TN, NO3--N, and TP in the SCSC-S/Fe composite system were 12.56 percentage points, 3.28 percentage points, and 17.59 percentage points higher than those in the S/Fe-SCSC composite system. Scanning electron microscopy (SEM) analysis revealed that the surface of the sulfur-iron composite filler in the SCSC-S/Fe composite system had a greater number of spherical denitrifying bacteria. X-ray diffraction (XRD) patterns of the sediment from the sulfur-iron composite filler indicated that PO43- in the effluent was primarily removed in the forms of FePO4, Fe3(PO4)2(OH)2, and Fe3(PO4)2·xH2O. Fe6(OH)12CO3 was also observed in the SCSC-S/Fe composite system. This indicated that the synergistic effects of heterotrophic denitrification, iron-based autotrophic denitrification, sulfur-based autotrophic denitrification, FeS autotrophic denitrification, and sponge iron denitrification were more effective in the SCSC-S/Fe composite system. Therefore, placing the solid-phase cellulose carbon source at the front end of the sulfur-iron composite filler was the optimal coupling method in the process design.
