合肥市城区流失水土污染特征研究
- Title:
- Study on Pollution Characterization of Urban Transfer Soil and Water in Hefei City
- 分类号:
- S153;X522
- 摘要:
- 利用降雨-径流过程中的采样与监测，研究道路面、草坪地和灌丛地径流中固体颗粒物、氮、磷等污染物浓度的变化特征。结果表明，城区降雨径流中初期污染物浓度明显高于后期，但不同下垫面上径流污染物变化规律有所差异。道路面径流污染物（SS，N，P）浓度在初期很高且下降幅度很大，末期则较低且趋于稳定；草坪地和灌丛绿地径流污染物从初期到末期基本呈平稳下降趋势。试验结果还表明，城区径流中输出的磷污染物以颗粒态为主，颗粒吸附态磷（PP）达到70%以上；氮污染物中颗粒态明显低些，但颗粒吸附态氮（PN）在40%～60%。
- Abstract:
- Using sampling and measuring storm-runoff in Hefei urban,the pollutants change characteristics of SS,N,P in storm runoff were investigated on the urban roadway,lawn and boskage.The results showed that the concentration of pollutants was substantially higher during the initial period of storm water runoff than lasted period,but the pollutants of storm water runoff on different underlying surfaces such as roads,lawns,and boskage had a different variety law.The concentration of runoff pollutants on roadway were higher and the declined rates were obvious,but in lasted period they were low and the declined rates were inconspicuous.The concentration of runoff pollutants on lawn and boskage had a low and balanced decline trends.The results also showed that particle phosphorus was the main form transported by runoff and PP is higher 70%;particle nitrogen was lower obviously and PN is 40%~60%.
