Environmental Impact Investigation of Nemone Tehran Slaughterhouse Using Integrated Methods AHP and TOPSIS

For surveying the environmental effects of Nemone Tehran Poultry slaughterhouse correlation Scaling Weighting Checklist measurement methods, TOPSIS and AHP Techniques are applied. Therefore at the beginning of the Checklist method by analyzing the project effects, the required criteria and options have been marked. For final validity of criteria under study, we used experts questionnaire .In order to set priorities for criteria and options and achieve the relative weight, AHP method is used in the form of the special vector technique by using the Expert Choice Software. The overall index is calculated by the sum of the criteria weight times criteria scale in each Checklist. TOPSIS method was employed to measure the results achieved by Checklist method. By determining the options and criteria, the weight of indices calculated as well as options graded. The results indicate that from the pollutions perspective in the slaughterhouse, wastewater weighted 1.278 is primary and sound; air and odour weighted 0.261, 0.216, 0.091 are the subsequent priorities. Social, cultural and economic environment, weighted 0.699, towards chemical and physical environment, weighted 0.237, and then biological environment, weighted 0.064, has higher rank. In social, cultural and economic environment in relation to quality of life, health weighted 0.783 was considered the first priority. Regarding the chemical and physical environment in relation to its effect on water resources, groundwater weighted 0.951 has achieved the first place. From the biological environment perspective and about the plantation, the greenspace weighted 1/041 dedicated to the slaughterhouse has been of the high priority. At the end, optimization of the slaughterhouse wastewater treatment system is advised as the most important approach in decreasing the harmful effects
