The Analysis about Pollutant Index of the Wastewater Originating from Small Vehicles Washing
Abstract:
The wastewater originating from small vehicles washing which comes from 30 car washing stations in Kuming is selected as research subjects and tested. The results turn to be as follows: the pollutant indexes of the car washing wastewater are chromaticity, SS, COD and LAS, which beyond the approved discharged standards of A, B, and C in varying degrees. There are differences in the same parameter values from diverse car washing stations, such as SS is up to 923 mg/L. Pollution levels of pollutants’ indexes are various and their differences are in those descending orders: Chromaticity>LAS>SS>COD. Therefore, when establishing treatment facilities, pollution levels should be specially taken into consideration. Moreover, car washing station need to consolidate managing measures and standardize the drains.
