Abstract


Grasp the purpose of the Urumqi River Basin, the main source of pollution of water pollutants and emissions ; comprehensive evaluation of the Urumqi River ( 2006-2008 ) water environmental quality and pollution status ; proposed Pollution Prevention Urumqi River Basin Environmental management suggestions . 2006-2008 by collecting the Urumqi River water quality monitoring data within various types of pollution sources in the basin in 2007 census data , the use of surface water environmental quality standards control , a single factor evaluation and integrated pollution index method , a comprehensive evaluation of water quality and analysis . 1) Yuejin Bridge is consistent with the hero bridge cross-section of major pollutants are DO, COD and F-; bridge section of the power supply company of major pollutants COD, Oil and CODMn; Gao households bridge section of major pollutants Oil COD and CODMn. 2 ) , four sections in the Gao household bridge section chemical oxygen demand concentration three years , the standard deviation of 8.51mg / L; Yuejin Bridge Section minimal change in the concentration of three years , the standard deviation to 0.79 g / L . 3 ) ,2006- 2008 , the concentration of petroleum contaminants space trend from upstream Yuejin Bridge to the heroes Bridge , slowly increasing concentrations ; into the city , the concentration of pollutants quickly last sectional households bridge concentration reached a maximum . Yuejin Bridge and heroic bridge section of oil pollutant concentration is very close to the standard deviation of less than 0.01mg / L; Gao household the bridge section interannual oil class maximum concentration reached 0.17mg / L standard deviation . 4) Yuejin Bridge hero bridge , and Gao households bridge section wet period and the water quality is good in flat water period , the power company bridge section level of water quality is better than the wet period . Conclusion 1) the Urumqi River Yuejin Bridge section and heroes bridge section with the class I water to reach the source of drinking water quality requirements ; bridge section of the bridge section of the power supply company and Gao households was Ⅳ water to achieve the requirements of agricultural irrigation water . 2 ) The main concentration of pollutants in the Urumqi River gradually increased from upstream to downstream ; significantly reduced water into the city . 3 ) industrial source emissions impact on the water quality of the Urumqi River lighter , the main sources of pollution is the the coastal living source emissions .
