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.

چکیده [English]

Due to its location in arid and semi-arid climates and also with the increasing growth of water consumption, Iran is facing a serious risk of water crisis in agriculture, drinking and industry. To deal with it, we must be more sensitive to the types of water consumption. The industrial sector is one of the major consumers of water resources in the country and water consumption management in this sector should be considered, in addition to saving water consumption, to meet the water needs of industries in the future. The present study was conducted on one of the large detergent factories in Qazvin province. A system boundary analysis is provided for a detergent and the range of water consumption factors is determined. Using the information received from the factory and related calculations, the total water footprint of the factory in 2019 is 26.64 cubic meters per ton of product. The amount of direct and indirect water footprints is estimated to be 0.658  and 25.9 cubic meters per ton of product, respectively, which indicates the high share of detergent production in water consumption. In this study, the gray water footprint in this industry is calculated to be 14.5 cubic meters per ton and the amount of footprint is very effective on the overall water footprint of the factory.
