Abstract :

Study aim is evaluating of Bojnord wastewater treatment location based‌ on indicators in locating the wastewater treatment. 15 information layer contain 8 indicators affecting the location and 7 right privacy Is processing in GIS software. To identify the weight of each index, the questionnaire was distributed between 25 experts of related sciences. Then, using AHP hierarchical decision making final weight of each indicator was calculated. In final step of combining weights and information layer in GIS software and remove areas with restrictions, Bojnord wastewater treatment location was evaluated. "Slop" and "the height difference to the city" variables by the final weight of approximately 0/20 and 0/21, have the greatest impact on the refinery location. Also, wastewater treatment current location, based on the principles and indicators, is located in unsuitable zone. In conclusion, the 3 proposed options with regard to the established criteria and restrictions, for the Bojnord wastewater treatment location, with the help of SAW model, related to the MADM methods collection, were studied that alternative number1, by placing in petrology area of arjelity argillaceous with shale interlayers, contains ammonites, akinopad and numerous orbitolina, in terms of status of most of indicators and privacy, were identified better than other options.
