摘要

  • 摘要: 为提高低碳氮比污水中易生物降解有机物的含量，实验设计了水解（H）/移动床生物膜反应器(AMBBR)/好氧（O）工艺，并与传统A/O工艺对比，考察其作为低碳源污水脱氮工艺的可行性。通过小试对比低温下（10.9~13℃）两工艺中污泥的反硝化性能，并进行了实验室规模的中试运行。小试结果显示，AMBBR两相污泥对硝酸盐的去除率比单纯反硝化污泥高出19.4%。中试结果表明，相同的运行条件下，两工艺对COD和NH3-N的去除效率相当，但H/AMBBR/O工艺对总氮的去除效率均优于传统A/O工艺；在各自最优工况下，前者平均总氮去除率较后者高出22.39%，且前者通过剩余污泥的回流水解实现了部分污泥减量化，尤其是对于温暖地区，该工艺能够有效改善低碳源污水脱氮性能。
    Abstract: The hydrolysis acidification (H)/anoxic moving biological biofilm reactor (AMBBR)/aerobic (O) process was employed to improve the content of easily biodegradable organisms in low carbon source wastewater, and it was compared with the conventional anoxic (A)/aerobic (O) process, to see its feasibility in nitrogen removal of low carbon source wastewater. Denitrification performance of both sludge from the two processes were investigated at low temperatures（10.9~13℃）, and the laboratory pilot scale operation of the two processes were also studied. Results from bench scale test show that the nitrate removal efficiency of two-phase sludge from AMBBR was 19.4% higher than that of single anoxic sludge. Also, results from pilot scale test showed that under the same conditions, the removal efficiencies of COD and ammonia were almost the same in both process, while total nitrogen removal efficiency in H/AMBBR/O process was always higher than that of A/O process, and the D-value attains 22.39% under their best conditions. Besides, in the process of H/AMBBR/O, sludge reduction was realized through backflow hydrolysis. It was believed that the H/AMBBR/O process could improve carbon source effectively, especially in warm areas.
