چکیده | ||
کشور ایران به دلیل واقع شدن در اقلیم خشک و نیمهخشک و همچنین، با رشد روزافزون مصارف آب در بخشهای کشاورزی، شرب و صنعت، با خطر جدی بروز بحران آب مواجه شده است. برای مقابله با این بحران، باید نسبت به انواع مصرف آب با حساسیت بیشتری برخورد شود. بخش صنعت یکی از مصرفکنندگان عمدۀ منابع آب کشور است و مدیریت مصرف آب در این بخش، باید مورد توجه قرار گیرد، تا علاوه بر صرفهجویی در مصرف آب، نیاز آبی صنایع در آینده نیز تأمین شود. مطالعۀ حاضر، روی یکی از کارخانههای بزرگ تولید مواد شوینده در استان قزوین صورت گرفته است. نوعی آنالیز مرز سیستم برای یک کارخانۀ تولید مواد شوینده ارائه شده و محدودۀ محاسبات عوامل مصرف آب را مشخص کرده است. با استفاده از اطلاعات دریافتشده از کارخانه و محاسبات مربوط به آن، در سال 2019 مقدار رد پای آب کلی کارخانه 64/26 مترمکعب بر تن محصول محاسبه شده است. میزان رد پای آب مستقیم و غیرمستقیم بهترتیب 658/0 و 9/25 مترمکعب بر تن محصول برآورد شده است که نشاندهندۀ سهم زیاد تولید مواد شوینده در مصرف آب است. در پژوهش حاضر، رد پای آب خاکستری در این صنعت 5/14 مترمکعب بر تن محاسبه شده و میزان رد پای آن روی میزان رد پای آب کلی کارخانه بسیار تأثیرگذار است. | ||
