Abstract:In order to get the characteristics of the sewer sediments in a mountainous city, the sewer sediments in Chongqing urban zones were selected. There were different characteristics for the sediments located in different areas. The size of the sediments was traffic area > cultural district > business forum > residential area. The density and sediment organic content (VSS/TSS) were positively correlated (R2 = 0.998). The content of sediment showed significantly differences in different functional areas. The size of COD was cultural district > residential area > business forum > traffic area. The sizes of TN and TP were cultural district > business forum > residential area > traffic area. The content of TP, which was compared with street dust, showed significantly enrichment characteristic. The content of heavy metals in traffic area was the biggest in all functional areas, and the max value of Cu、Zn、Pb、Cd was 303.5、539、104、1.14mg/kg respectively.
