中文摘要：

采用厌氧SBR反应器,分别以配水培养和以实际晚期垃圾渗滤液培养的厌氧氨氧化菌为研究对象,考察了不同基质浓度下,SBR改进式连续进水方式与一次性进水方式对厌氧氨氧化工艺运行性能的影响.结果表明,当处理人工配水时,在中低进水浓度下（NO2--N≤400mg/L）,与改进式连续进水方式相比,宜采用一次性进水方式运行;在高进水浓度下（NO2--N≥400mg/L）改进式连续进水方式比一次性进水方式优势明显,特别是在5h改进式连续进水方式下,平均比污泥脱氮速率增加至39.11mg N/（g VSS·h）,相比一次进水方式效率提高40%.当处理进水NO2--N浓度为（300±20）mg/L的实际晚期垃圾渗滤液时,5h改进式连续进水的SBR比污泥脱氮速率最高.由于晚期渗滤液较配水成分复杂,使得厌氧氨氧化菌面临有机物和有害物质的影响,其厌氧氨氧化的反应速率低于同等基质浓度配水条件下的厌氧氨氧化反应速率。

英文摘要：

Different feeding modes with different influent substrate concentration were investigated using anaerobic SBR, with the conditions of synthetic wastewater and real mature landfill ieachate, respectively. The results showed that when treating low concentration of synthetic wastewater （NO2 -N≤400mg/L）, the feeding mode of 5min was a better choice for Anammox. When treating high concentration of synthetic wastewater （NO2 -N≥400mg/L）, the continuous feeding mode of 5h was the best choice for Anammox. Under the continuous feeding mode of 5h, the average nitrogen removal rate （ANRR） increased to 39.11 mgN/（gVSS.h） and enhanced by 40% comparing with the feeding mode of 5min.When treating the real mature landfill leachate with nitrite concentration of 300±20mg/L, ANRR of 5h was maximum comparing with other feeding modes. Because of the mature landfill leachate contained a little of biodegradable organics and lots of hazardous substances, the ANRR of treating mature landfill leachate was lower than that of treating synthetic wastewater.
