英文摘要	微藻对水体有明显的净化作用,探讨了在开放条件下蛋白核小球藻及蛋白核小球藻- 大型溞修复系统对污水中磷的去除效果。研究表明接种8 h 蛋白核小球藻对磷达到过饱和吸收,过饱和吸收量是(3. 12 ±0. 39)×10~(-10)mg/cell; 接种量1. 00 ×10~5 cells/mL ~3. 72 ×10~6 cells/mL 无菌培养96 h 对总磷的去除率达到75%; 正常生长过程中藻细胞除磷量(饱和含磷量)为(1. 46 ±0. 05)×10~(-10)mg/cell; 在每日补充营养盐的开放环境下, 72 h ~216 h 藻细胞除磷量(饱和含磷量)稳定在(1. 50 ±0. 50)×10~(- 10)mg /cell,微藻系统稳定运转时除磷量为(0. 06 ± 0. 01)mg /(L·d),此时藻密度为1. 11 × 10~6 ~ 3. 79 × 10~6 cells /mL。藻- 溞修复系统表明,藻密度在9. 28 × 10~5 ~ 1. 60 ×10~6 cells /mL 范围内,藻溞数量比为3. 02 × 10~6∶ 1时藻- 溞修复系统能稳定运行。; Microalgae has obvious effect on water purification,this paper explored phosphorus removal capacity of Chlorella pyrenoidosa in open system and purification effect of wastewater by Algae-Daphnia system. It was indicated that after incubated in sterile wastewater for 8 h,algae can achieve max amount of phosphorus absorption,(2. 99 ± 0. 45) × 10~(-10) mg/cell. After incubated in sterile wastewater for 96 h,the rate of phosphorus removal reached to 75%,when inoculation quantity of algae was between 1. 00 × 10~5 cells/mL and 3. 72 × 10~6 cells/mL. The phosphorus removal capacity of each multiplied algae cell(saturated phosphorus content) was (1. 46 ± 0. 05) × 10~(-10) mg/cell in the sterile wastewater,and it was(1. 50 ±0. 50) ×10~(-10) mg/cell in the open system from 72 h to 216 h,under the condition that nutrition was added to the system every day. The amount of phosphorus removal was (0. 06 ±0. 01) mg/(L·d), when the system worked well and algae's density was between 1. 11 × 10~6 and 3. 79 × 10~6 cells/mL. Algae-Daphnia system was constructed based on a controlled density of algae,at which Chlorella pyrenoidosa had great capacity of uptaking phosphorus. Algae-Daphnia system can work well by controlling the amount ratio of Chlorella /Daphnia at 3. 02 × 10~6∶ 1,when algae density was between 0. 928 × 10~6 millions and 1. 60 × 10~6 millions cells /mL.
