Abstract :
Background and Objective: One of the most important problems caused by industrial and service development in Ray city is the production of a high volume of wastewater that its non-systematic discharge to the environment can lead to contamination of surface water and groundwater resources or by using it in agricultural uses Soil contamination. Therefore, in this research, the industrial and service centers of the waste water producer in Ray city were identified to provide a solution to improve the status.
Material and Methodology: To this end, wastewater contamination centers in the Ray city were identified and the chemical and biological properties of wastewater of these centers including pH, COD, BOD and Total Coliform were evaluated based on the average two-year period (1395-1394) and the spatial distribution map of concentration The wastewater pollutants associated with these centers in the Ray city were prepared using the GIS software and the IDW zoning method.
Findings: In this study, 17 main waste water producers were identified, including seven livestock and a waste disposal center and a vegetable oil factory in Ray city.
Discussion and conclusion: The results show that the effective strategy to improve the situation, equipping the pollutant units with the wastewater treatment system, and improving the wastewater treatment system in units that have a purification system, as well as reducing water consumption in the production process, which leads to a reduction in the amount of wastewater produced. And monitoring of responsible organizations in this field.
