| Groundwater pollution possess invisibility and hysteresis quality.Petroleum and chemical industry is a heavy pollution industry,especially.The feature of the pollution is varied and complex.The environmental risk and protecting target is determined difficultly.There isn't a concrete index system to describe the petrochemical park pollution impact on groundwater environment.Groundwater is polluted by surface water pollution.However,construction projects and the planning of groundwater assessment is-short for surface water pollution.Concrete analysis of this situation and the method for quantifying the groundwater pollution are pressed for consideration.The surface water of Daqing area has been polluted.The surface water pollution is certain representative which caused by oil exploitation,By calculating the amount of water supply in the lake,the groundwater supply was determined by the amount of the water supply in the lake,which was 6906.8 × 104m3/a.The environmental impact analysis was carried out in the petrochemical complex.CH2Cl2 and Cr6+ were selected as evaluation factor To make environment impact assessment index system of the Daqing petrochemical industrial park perfect.The oil pollution was selected as background value evaluation factor analysis of surface water process and the main pollutants.To make new factor compared and contrast analysis of surface water supply.The analytical method was used to predict the case.CH2Cl2 and Cr6+ were significantly higher than the above,and the forecast was more accurate.After considering lake supply replenishment,The maximum migration distance and influence of oil pollution was obviously increased,and the forecast was more comprehensive.Provide a reference evaluation factor.Only one large industrial park near surface drainage,the influence of surface water background value was exceeded with the park development.It has been provided construction direct relationship to reference method. |
