Study On Shijiazhuang Dust Pollution Chatacteristic,Cause Of Formation And Prevension Meaure

Shijiazhuang is a typical city in the north of China in which coal consumption takes up over 80 percent of the energy structure .So its air pollution presents the typical "coom-model" and its distribution characteristic is obvious space-time with economy growth and city scale expanding of Shijiazhuang , dust pollution is becoming more and more serious. There by, it restricts the economic development of the city.This study stresses on the characteristic of dust pollution of Shijiazhuang and main influence factors which lead to dust pollution. Besides, it modifies the diffusing model by CMBT.Using the model, the predicted concentration accords with the fact preferably. This study also predicts the air quality of Shijiazhuang in 2005. The results show that in order to make the air quality of Shijiazhuang in 2005 reach the programming environmental objects, control and treatment on organized discharge source and dust must be done well simultaneously. At last this study brings forward the control project of dust pollution of Shijiazhuang.
