چکیده

آثار زیست‏محیطی انسان بر کرۀ زمین در زمینه‏های مختلفی قابل بررسی است. یکی از زمینه‏هایی که اهمیت زیادی در کرۀ زمین دارد، انتشار گاز دی‏اکسید‏ کربن توسط انسان است. یکی از هزاران فعالیت بشر که به انتشار گاز ‏دی‏اکسید کربن به محیط منجر می‏شود، فعالیت مربوط به تأمین آب مصرفی است. در این مقاله به بررسی حجم گاز ‏دی‏اکسید کربن انتشاریافته ناشی از سیستم تأمین ‏آب ‏شرب شهر سپیدان پرداخته شده است. محدودۀ زمانی این پروژه یک‏سال بوده است. نتایج بررسی‏های این مطالعه نشان می‌دهد در شهر سپیدان از تعداد یک حلقه چاه با انرژی مصرفی 81318 کیلووات ساعت، یک چشمه با انرژی‏ مصرفی 102234 کیلووات ‏ساعت و ساختمان ‏ادارۀ آب ‏و فاضلاب با انرژی مصرفی 5491 کیلووات ساعت، به‌ترتیب مقدار 48769- 1067 و 3293 کیلوگرم ‏دی‏اکسید ‏کربن در سال تولید می‌شود. همچنین، نتایج این تحقیق نشان داد به ازای تأمین یک متر‏مکعب آب شرب در شهر سپیدان حدود 38 گرم ‏دی‏اکسید کربن تولید می‏شود. نتایج این تحقیق نشان داد تأمین آب از چشمه در نقطه‏ای با ارتفاع بیشتر نسبت به همۀ مناطق شهر به دلیل توپوگرافی خاص شهر سپیدان، که به صورت پستی و بلندی‌های پرشیب است، نیاز به انرژی بسیار کمتری دارد و به دنبال آن آلودگی یا دی‌اکسید کربن کمتری منتشر می‏کند.

چکیده [English]

Human environmental impacts on the earth can be examined in various fields. One of the areas of great importance is carbon dioxide emissions by human. One of the thousands of human activities that lead to carbon dioxide emissions into the environment is the supply of water. This paper examines the amount of carbon dioxide released by the drinking water supply system in Sepidan. This project took place within a year's time. The results of the surveyes show that in Sepidan, from one well with an energy consumption of 81318 kwh, one spring with an energy consumption of 102234 kwh, and the building of water and sewage organization with an energy consumption of 5491 kwh, amounting to 1067, 48,769 and 3293 kilograms of carbon dioxide release per year. Also, the results showed that 38 grams of carbon dioxide is produced for the supply of one liter of drinking water in the Sepidan. The results of study showed that the supply of water from the spring at a higher altitude point than areas of the city due to the specific topography of the Sepidan, Which is in the form of sloping, requires much less energy, and releases less contamination or carbon Dioxide.
