摘要:
为了降低城市污水处理厂深度脱氮过程中有机碳源的消耗量，提出了短程反硝化/厌氧氨氧化双滤池系统，并通过试验考察了厌氧氨氧化滤池的脱氮性能及菌群结构。结果表明，厌氧氨氧化滤池在进水NH4+-N和NO2--N平均浓度分别为9.9、9.1 mg/L条件下，出水NH4+-N和TN平均浓度分别为2.5、9.5 mg/L，达到了《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准，对应的滤池HRT为15 min，容积氮去除速率为1.0 kg/(m3·d)。滤池中的厌氧氨氧化菌属为Candidatus Kuenenia和Candidatus Brocadia，相对丰度分别为4.33%和2.70%。与传统反硝化滤池相比，短程反硝化/厌氧氨氧化双滤池系统可节省有机碳源62%，同时可降低污泥产量，减少滤池反冲洗次数。
Abstract:
In order to reduce organic carbon source consumption in advanced denitrification processes, a partial denitrification and anaerobic ammonium oxidation (Anammox) double biofilter system was proposed, and the nitrogen removal performance and microbial community composition of the Anammox biofilter were investigated. When the average concentrations of NH4+-N and NO2--N in influent of the Anammox biofilter were 9.9 mg/L and 9.1 mg/L,the concentrations of NH4+-N and TN in the effluent were 2.5 mg/L and 9.5 mg/L, respectively, which met the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). HRT of the biofilter was 15 min, and the volumetric nitrogen removal rate was 1.0 kg/(m3·d). The Anammox bacteria in the biofilter belonged to Candidatus Kuenenia and Candidatus Brocadia with relative abundances of 4.33% and 2.70%, respectively. Compared with traditional denitrification biofilter, the partial denitrification and Anammox double biofilter system could save 62% of organic carbon source and reduce sludge production and backwash time.
