摘　　要：由序批式活性污泥法(SBR)和生物选择器构成1种新型SBR工艺,以通过污泥转移实现除磷优势菌种的筛选,强化除磷效果。以生活污水为处理对象,研究了转移量和COD/ρ(PO_4^(3-)-P)对释磷的影响。结果表明,比释磷速率(SPRR)与污泥转移量关系为y=exp(1.28+5.468.15x^2)(y=SPRR/(mg·g^(-1)·h^(-1))),中值误差为1.52%,系统在33%的转移量下其最大比释磷速率可达8.97 mg/(g·h);进水COD/ρ(PO_4^(3-)-P)对释磷和除磷影响显著,COD/ρ(PO_4^(3-)-P)=45~96时,比释磷速率、PHB合成量、释磷量较高,磷去除效率可达90.8%以上,出水PO_4^(3-)-P的质量浓度在0.5 mg/L以下,这说明该工艺可适用于南方低碳源污水。The new SBR process consists of multi-SBRs and a bio-selector. The remarkable characteristic of the SBR Process was to achieve the goal of screening dominant bacteria of phospborus removal and strengthening phosphorus removal effect through transferring activated sludge. With domestic sewage as treatment object, this paper researched on the effect of phosphorus anaerobic release with different sludge cycling ratios and different COD/p （PO43-P）. The results indicated that the relationship between specific phosphorus release rate and sludge transfer amount was y=exp （1.28＋5.468.15x2） （y=SPRR/（mg.g-1 .h-1））, and median error was 1.52%. When sludge transfer amount was 33%, the maximum specific phosphorus release rate could reach 8.97 mg/（g.h）. The COD/p（PO43- -P） had a significant effect on phosphorus release and removal, when the ratio was controlled between 45 and 96, the specific phosphorus release, the synthetic quantity of PHB and phosphorus release amount were rather high, also, the removal rate of phosphorus could reach above 90.8%, the mass concentration of PO43--P in effluent was below 0.5 mg/L. It could be concluded that the process is applicable to the low-cerbon concentration sewage in the South.
