  • 摘要: 通过构建室内潮汐流沸石-石灰石混合填料和沸石填料人工湿地装置，探讨了不同基质人工湿地对SBR尾水中污染物的去除效果。结果表明，沸石对NH4+-N的吸附能力强，且潮汐间歇运行方式使系统一直保持高效的去除NH4+-N的能力，石灰石中Ca、Mg含量高，对P有较好的吸附。潮汐流沸石-石灰石混合填料、沸石填料人工湿地对NH4+-N的去除率分别为99.8%、96.7%，对TP的去除率分别为59.6%、24.9%。石灰石呈中性偏碱性，有利于水中硝化菌、反硝化菌和某些异养菌群的生长。潮汐流沸石-石灰石混合填料、沸石填料人工湿地对TN的去除率分别为43.0%、28.0%，对COD的去除率分别为43.4%、36.7%。沸石-石灰石混合填料人工湿地上层基质中微生物量最高，达到20.45 nmol·g-1填料（相当于E.coli大小的细胞2.0×109个）。2组系统中微生物量具有较明显的分层现象，且上层高于下层，这与污染物随水流推流方向的浓度变化一致。
    Abstract: Two tidal flow constructed wetlands (TFCW), one with zeolite-limestone-mixed packing and one with zeolite-only packing, were set up on a lab scale to explore the impact of purification performance on SBR tidal water. Results showed that zeolite had strong adsorption affinity for NH4+-N, and the tidal intermittent operation mode removed NH4+-N with high efficiency. The Ca and Mg content was high in the limestone, therefore the limestone adsorbed P well. In the zeolite-limestone-mixed packing and zeolite-only packing TFCWs, the removal rates for NH4+-N were 99.8% and 96.7%, respectively, and for P were 59.6% and 24.9%, respectively, in the plateau stage. The limestone was weakly alkaline, which was beneficial for the growth of nitrifying bacteria, denitrifying bacteria, and some heterotrophic bacteria in the water. In the zeolite-limestone-mixed packing and zeolite-only packing TFCWs, the removal rates for TN were 43.0% and 28.0%, respectively, and for COD were 43.4% and 36.7%, respectively, in the plateau stage. The upper layer of the zeolite-limestone-mixed packing TFCW had the most bacteria, with 20.45 nmol·g-1 packing, amounting to 2.0×109 cells (as they are the same size as E. coli). From microbial quantity, it was determined that the upper layer was further along than the lower layer, which was consistent with the change in pollutant concentration as well as water flow direction.
