چکیده

ارزیابی ریسک محیط زیست، از بخش­های بسیار مهم در سیستم مدیریت محیط زیستی بوده و نقش بسیار مهمی در بهبود شاخص­های کیفیت و عملکرد محیط زیستی ایفاء می­نمایند. در این تحقیق ارزیابی کیفیت محیط زیستی پساب منطقه ویژه اقتصادی انرژی پارس از سال 2011 تا 2014 با استفاده از منطق فازی بررسی شده است. در منطق چند ارزشی فازی با کمی­سازی متغیرهای زبانی و استفاده از سایر داده­های کمی محیط زیستی و ارائه شاخص­های فازی می­توان به ارزیابی کیفیت و ریسک محیط زیستی یک واحد صنعتی دست یافت. شاخص فازی کیفیت پساب FWWQI1 در مطالعه موردی از سه آلاینده: COD2، BOD3، TSS4 و خصوصیت pH تشکیل شده است. در مدل ارائه شده در این مقاله حدود سطوح کیفیت فازی در توابع عضویت با بهره­جویی از نتایج تحقیقات پیشین، استانداردهای محیط زیستی و قضاوت­های کارشناسان محیط زیست اتخاذ گردیده­اند. بر اساس نتایج مدل ارائه شده، آلاینده­های مؤثر در بالا بردن ریسک محیط زیستی، COD و BOD شناخته شده­اند و شاخص­های فازی کیفیت محیط زیستی پساب پالایشگاه A در سال 2013 معادل 8/48 (خوب) و در سال 2014 معادل 44 (خوب) به­دست آمده است. این امر نشان­دهنده استانداردسازی کامل پالایشگاه A در زمینه کنترل آلودگی­های پساب بوده که دارای روند رو به بهبود شاخص­های کیفیت و ریسک محیط زیستی بومی است و از جمله مهم­ترین دستاوردهای سامانه­های مدیریت ISO14001 و HSE_MS5 در منطقه مورد نظر به شمار می­رود.

چکیده [English]

     Environmental risk assessment is one of the most important parts of the environmental management system and plays a significant role in improving the quality indices and environmental performance. The cost of damage (direct, indirect, and intangible), and the consequences of pollution and environmental accidents are very high, causing significant damage to organizations and countries every year. Therefore, it is necessary that risk management, which involves identifying, assessing and controlling risk, is implemented at the level of companies that have the potential capacity for such events. In this research, the environmental quality assessment of the Pars Special Economic Region from 2011 to 2014 has been investigated using fuzzy logic. Fuzzy logic is a multi-valued logic that allows the grading of values to work with the user's values in a system.
