  • 摘要: 为避免因FAS释放过量有机物和氮而产生的潜在不利影响，分析了以给水厂铁铝泥(FAS)构建过滤柱处理富营养化河水的特征与机制，研究了以厌氧热处理改性后的FAS作为辅助基质(2%)构建过滤柱。结果表明：在对其他性质无影响的情况下，FAS的添加显著提高了过滤柱对水体中磷的去除率，促使出水磷浓度在整个运行期间小于0.01 mg·L-1；被FAS吸附的磷主要以NaOH提取态、HCl可提取态和残渣态存在。高通量测序分析结果表明，FAS的添加促使过滤柱中富集了Rhodoplanes、Sulfuritalea、Nitrospira、Leucobacter、Geobacter、Dechloromonas等有助于生物地球化学循环和复合污染控制的菌群。FAS作为辅助基质构建过滤柱可有效控制富营养化河水中磷污染。
    Abstract: For avoiding the potential excessive release of organic matter and N from ferric and aluminum sludge (FAS), the characteristics and mechanisms of treating eutrophic river water by reusing FAS to construct filtration columns were analyzed, and FAS modified by anaerobic heat treatment was taken as an auxiliary medium in filtration columns (2%).The results indicated that under the conditions of no influence on other properties, P removal rate from the river water was significantly improved by FAS addition in filtration column, and P concentrations in the effluent was lower than 0.01 mg·L-1 during the whole test. The adsorbed P by FAS were mainly in NaOH extractable, HCl extractable, and residual forms. High throughput sequencing analysis indicated that addition of FAS promoted the enrichment of functional bacteria e.g., Rhodoplanes,Sulfuritalea,Nitrospira,Leucobacter,Geobacter,Dechloromonas that were beneficial to biogeochemical cycles and complex pollution control. FAS can be taken as an auxiliary medium of filtration columns and effectively control P pollution of eutrophication river.
