Determination of Volume and Physico-Chemical Properties of Wastewater Produced at Solid Waste Transfer Stations in Shiraz

Solid Waste transfer stations are one of the important components in the process of waste collection and transfer. Carrying out of various activities such as washing and car washes of machinery and station area in this place leads to the production of wastewater. Therefore, due to the importance of the information about the physical and chemical properties of wastewater generated at the transfer stations for their proper management, the purpose of this study is Determination of the volume and physic - chemical properties of wastewater produced at waste transfer stations in Shiraz. This research was carried out on two waste transfer stations in Shiraz, in October 2013. For this purpose, 9 samples from Transfer Station No. 1 (Pirnia) and 18 samples were taken at Transfer station No. 2 (Adelabad) during three consecutive weeks. Also, to determine the amount of effluent produced by considering the existence of storage ponds at Adelabad Transfer Station during a week, the volume of effluent was estimated by recording the height of leachate within the ponds. The average amount of wastewater produced at the Adel Abad transfer station (Number 2) was 8.6 cubic meters per day. The results showed that in general, the values of the parameters studied at the transfer station of Pirnia (Number 1) are more than AdelAbad station. The results also showed that there is a significant difference between the parameters of TDS, TSS and COD in two transfer stations (P-value <0/05). Pearson test results also showed a significant correlation between the TSS parameters with TDS, COD with TDS and EC with COD. In general, the results of the study showed that the values of the parameters in the Pirnia transfer station are more than AdelAbad station. So, the wastewater of the station No. 1, due to similar its characteristics to leachate, should be transported to the evaporation ponds. However, the wastewater from the carwash and repair pond at the No. 2 transmission station can be sent to the refinery system.
