摘　　要：从鱼塘底部污泥中分离驯化得到一株高效聚磷菌株P5,采用厌氧/好氧（A/O）方式培养,在厌氧阶段3 h的最大释磷量为17 mg/L;在好氧条件下培养16 h后,P5对总磷（PO43--P）浓度为10~30 mg/L的模拟废水的除磷率均可保持在90%,COD的去除率达到82.1%。染色实验表明,P5是革兰氏阴性球杆菌,菌体内含有异染颗粒。A strain of bacterium named P5with high capability of phosphorus accumulation was isolated from sludge of a fish pond.Using the culture of anaerobic/aerobic（A/O） to strain P5,the highest amount of phosphorus release was 17 mg/L for 3 h in the anaerobic period.Under the aerobic condition,the highest rate of phosphorus removal for P5 of simulated wastewater containing PO3-4-P of 10~30 mg/L was about 90% and removal rate of COD was 82.1% after 16 h.The dyeing test showed that P5 is gram-negative coccobacillus and has metachromatic granule in its cell.
