| 摘 要： | 对滇池流域大清河生物稳定塘系统中的水质净化效果进行了分析,同时对各塘中的浮游藻类种类组成、细胞密度和多样性进行了调查。结果表明,当污水流经预处理塘、好氧塘、水生植物塘、养殖塘的过程中,pH、DO、叶绿素a浓度呈逐渐上升趋势,TN、TP、NH_4~+-N、BOD_5和COD浓度呈逐渐下降趋势,生物稳定塘系统对TN、TP、NH_4~+-N、BOD_5和COD的去除率分别达29.29%,48.68%,33.68%,68.14%和71.25%。叶绿素a浓度和pH(r=0.955,P0.05)、DO(r=0.992,P0.01)显著正相关,而和TN(r=-0.936,P0.05)、TP(r=-0.925,P0.05)以及NH_4~+-N(r=-0.927,P0.05)等显著负相关。在塘系统中,共出现浮游藻类53种,藻类种类数和生物多样性呈增加趋势,总细胞密度呈下降趋势;塘系统中共出现6种藻类优势种,其中绿色微囊藻和惠氏微囊藻细胞密度呈现出逐渐下降的趋势,梅尼小环藻、啮蚀隐藻、美丽网球藻和球囊藻细胞密度呈现出逐渐上升的趋势。

| Abstract: | Wastewater treatment effect,together with species composition,cell densities and diversity of phytoplankton,was investigated in biological stabilization ponds of Daqing River.The results showed that pH,DO and chlorophyll-a concentration increased gradually,and TN,TP,NH_4~+-N,BOD_5 and COD decreased gradually when wastewater flew from the first pond to the last pond. The removal rates of TN,TP,NH_4~+-N,BOD_5 and COD in biological stabilization ponds were 29.29%,48.68%,33.68%, 68.14%and 71.25%,respectively.Ch... |
