A Primary Study about Water Quality Characteristics of Urban Constructive Sites Wastewater
Abstract:
The wastewater originating from fifteen different constructive sites in Yunnan is selected as research subjects, and then detecting the possible pollution index in the wastewater. It turns out to be that unattainment rate of SS is as high as 93.5%; the average contents of COD and BOD5 are 632.52mg/L and 255.39mg/L, both of which are over the emission standards to 66.7%; production wastewater is weakly alkaline; other index is beyond the approved discharged standards slightly. The main pollution factors of urban constructive sites wastewater are SS, COD, BOD5 and pH. The secondary pollution factors are petroleum, TN, TP and animal and vegetables Oil.
