Determination of industrial and urban runoff quality of Southern Pars economical special energy zone for renewed usage

摘要

Urban runoff is valuable and restoring source in most of arid and semi arid zone in Iran. Surface runoff has been gathered by canals from Pars economical especial energy zone and then slopping to Persian Golf. This behavior causes to remove out of hand the water sources and can be a treat for natural ecosystem of case study area. Five stations have been chosen to study the quality of industrial and urban runoff. The average of physical and chemical tests results has been showed that runoff after omitting first flush can be used as a usable source to inject ground water. According to heavy metal tests in whole stations, the concentration of heavy metal has been ranged in standard limit.
