摘要: 本实验以海河干流天津段水体为对象，对其中四种典型共存藻类（即铜绿微囊藻、小球藻、卵囊藻和席藻）在不同氮磷营养盐环境条件下的响应生长规律进行了过程表征及动力学研究。实验结果表明，N/P在10~40范围适宜藻类生长，N/P为10时藻类比增长率最大；氮浓度水平在2.0~15 mg·L-1、磷浓度水平在0.2~1.5 mg·L-1内，藻类比增长率随着氮磷浓度的升高而增大，当氮浓度为15 mg·L-1，磷浓度为1.5 mg·L-1时达到最大，优势藻为卵囊藻；通过Monod藻类生长动力学分析得出，藻类最大比增长率为0.050 8，半饱和常数为0.157，表明目标河段水华暴发风险相对较低，且磷是藻生长限制性因子。

Abstract: Simulative tests were conducted in order to study four typical coexisting algae (Microcystis aeruginosa, Chlorella vulgaris, Oocystis sp., and Phormidium.), the response of growth law and the kinetics under different nitrogen and phosphorus nutrient conditions. The Haihe River in Tianjin was considered as the research object. The results showed that (1) a N/P ratio within 10-40 allowed faster algal growth that was particularly vigorous once the N/P ratio equaled 10; (2) the algal growth-rate increased with the increase in N or P concentrations (CN 2.0-15 mg·L-1 and CP 0.2-1.5 mg·L-1), and it reached an optimal value when the abundance of N and P reached 15 and 1.5 mg·L-1 respectively; (3) Oocystis sp. was the dominant species; (4) Monod kinetic analysis revealed that the maximal increment rate was 0.0508 and the semi saturation-constant was 0.157, indicating a confining role of phosphorus on algal growth in the target river.
