Abstract

Background: The current research was carried out to assess the environmental impacts caused by Tehran Poultry Slaughterhouse of Nemone and to offer an Environmental Management Plan.
Methods: In this research, Technique  for Order  Preference by  Similarity  to  Ideal Solution (TOPSIS), as one of the most reliable techniques from  Multi Attribute  Decision  Making (MADM),  was applied  to assess environmental impacts caused by Tehran Poultry Slaughterhouse of Nemone. Thus, by determining the related options and criteria of decision making Matrix, the weight of indices and options were calculated and graded. After identification and prediction of the slaughterhouse impacts on the environment, he required criteria and potential options were identified through analyzing the impacts. Delphi questionnaire was applied to finalize the introduced criteria. Then TOPSIS method was utilized in 6 steps.
Results: Among the most significant impacts in the slaughterhouse, the first priority was allocated to the wastewater with the weight of 1following the noise, air and odor pollution with the weights of 0.664, 0.508 and 0.327 respectively. Noise assessment results indicated that the measured noise was beyond the permissible level. The results of air pollutions experiments were lower than that of the standard.
Conclusion: The results indicated that the effluent quality was not suitable to be discharged into the surface water or wells and it was not suitable for irrigational and agricultural purposes too. To minimize the environmental harmful impacts of slaughterhouse, the environmental management plan was proposed of which the most important case was the optimization of the wastewater treatment system.
