Calculation of Urban Domestic Pollutants and the Spatial Distribution in Haihe River Basin
The approach of calculating total discharge of the pollution sources of urban life is proposed, and the major pollutants including COD, NH3-N, BODs, TN (total nitrogen)and TP (total phosphorus) discharge are respectively 59.44×104t, 9.51×104t, 28.37×104t, 11.61×104t and 1.23×104t in Haihe River basin in 2005. The spatial distribution of the total discharge of pollution and discharge per capita daily are analyzed. The results show that main pollution regions with large discharge of urban domestic pollutants in Haihe River basin are Beijing city, Tianjin city, and trans-juris regions. It is different in the special distribution of pollutant discharge per capita daily. The cities with largest discharge of COD, NH3-N, BOD5, TN and TP per capital daily are respectively Shandong Dezhou,Shanxi Datong, Shanxi Jinzhong, Shanxi Datong and Beijing City. The capacity of urban sewage treatment is related with GDP per capital and the city size. The bigger is GDP per capital, the stronger is capacity of urban sewage treatment. Meanwhile, the city size and the capacity of urban sewage treatment also have a positive correlation.
