摘    要:物理性能和生物活性是活性污泥法中两个重要的关注方面,为解决运行控制中这两方面的矛盾,对不同活性污泥系统中的污泥物理结构和呼吸过程进行分析.利用7个不同活性污泥系统中的污泥,对其粒径、分形维数、压缩沉降性能、吸附性能和呼吸图谱等方面进行研究分析.结果表明,物理性能指标和呼吸速率之间存在较好的相关关系,其中污泥粒径(d)与内源比呼吸速率(SOUR_e)和最大比呼吸速率(SOUR_t)呈指数负相关(R~20.9);分形维数(D_f)与SOUR_e和SOUR_t呈线性负相关(R~20.8);压缩指数(SCI)和污泥指数(SVI)与SOUR~2_e呈对数正相关(R0.9);平衡吸附量(Q_(max))与准内源比呼吸速率(SOUR_q)和SOUR_e呈线性负相关(R~20.9).从而得出活性污泥正常运行条件下的最佳物理性能和活性范围:SVI为50~120 mL·g~(-1),SOUR_e为6.27~7.55 mg·(g·h)~(-1),d为205.80~228.12μm,D_f为1.56~1.60,R_(n/t)为0.02~0.03,Q_(max)为508~636 mg·g~(-1).

关 键 词:活性污泥  物理结构  比呼吸速率  生物活性  吸附性能
