People's awareness of environmental protection is increasing year by year, and environmental pollution caused by the fire is also being controlled. This article briefly introduces the fire accident's impact on the environment, the systematic analysis of the fire accident in the source of pollution and its harm. Combined with the existing way of fire fighting and rescue fire accident, the pollution control method is proposed.展开更多

The evolution of pollutant plumes under different operation schemes of the Three Gorges Reservoir and three kinds of pollutant discharge types were calculated with the MIKE 21 AD software. The feasibility and effectiveness of the reservoir emergency operation when pollution accidents occur were investigated. The results indicate that the emergency operation produces significant effects on the instantaneous discharge type with lesser effects on the constant discharge type, the impact time is shortened, and the concentration of pollutant is reduced. Meanwhile, the results show that the larger the discharge is and the shorter the operation duration is, the more favorable the result is.展开更多
