合肥市区周边地表水体形态磷的研究

选取合肥市周边代表性的地表水体董铺水库、天鹅湖、翡翠湖为研究对象，运用地表水和污水监测技术规范中的标准方法，对3个水体的TP、DTP、PP、DIP、DOP进行监测，并做了初步研究和分析。结果表明，天鹅湖水体中总磷的平均浓度为O，102mg／L，符合V类标准要求，水体中磷主要以DTP和DOP的形式存在，TP—DIP显著正相关；董铺水库总磷的平均浓度为0．031mg／L，达到Ⅲ类标准，磷主要以DTP和DIP的形式存在，其中TP与DTP之间高度显著正相关；翡翠湖水体中总磷的平均浓度为0．060meCL，达到IV类标准，水体中磷主要以ADTP的形式存在，其@TP与PP之间显著正相关，PP在该湖泊中占有重要的地位。

Various Svecies of Phosvhorus in Surface Water around Hefei Citv

This paper took Swan Lake, Dongpu Reservoir and Feicui Lake as the research objects to discuss the concentrations and correlation of various species of phosphorus. The results were obtained by standard methods in Technical Specifications Requirements for Monitoring of Surface Water and Waste Water. Results show the average concentration of TP in Swan Lake is 0.102 mg/L and is at Grade V. Among various species of P in Swan Lake, DTP and DOP are the main existing forms. In addition, the positive correlation of TP to DIP has been found in this lake. The average concentration of TP in Dongpu Reservoir is 0.031mg/L and is at Grade ]]I. DTP and DIP are the dominant species of P in Dongpu Reservoir. Among various species of P in this reservoir, there are significant positive correlations between TP and DTP. The average concentration of TP in Feicui Lake is 0.060 mg/L and is at Grade IV. Among various species of P in Feicui Lake, DTP is the main existing form. The positive correlation of TP to PP has been found and PP holds an important position in this lake.
