چکیده

فاضلاب رنگرزی یکی از مهم‌ترین مشکلات زیست‌محیطی صنعت نساجی است. این فاضلاب حاوی آلاینده‌های مضری برای سلامت انسان و محیط‌زیست است. انعقاد الکتریکی (EC) یک فناوری امیدوارکننده برای تصفیه فاضلاب رنگرزی است. این فناوری با عبور جریان الکتریکی از فاضلاب که با تولید یون‌های فلزی به‌عنوان منعقدکننده عمل کرده، آلاینده‌ها را از آب جدا می‌کنند. در تحقیق پیش‌رو ابتدا به معرفی سامانه EC و سازوکار عملکرد آن، سپس به مؤلفه‌های تأثیرگذار بر عملکرد سامانه در حذف رنگزا و میزان اکسیژن‌خواهی شیمیایی پرداخته شده است. همچنین مطالعات انجام پذیرفته در زمینه استفاده از این فرآیند در تصفیه فاضلاب رنگرزی پارچه بیان شده است. به‌علاوه جنبه‌های اقتصادی فرآیند EC و توصیه برای بهبود آن نیز ارائه شده است. در انتها چالش‌ها و چشم‌انداز آینده فرآیند مذکور بررسی شده است. در مجموع، این مقاله مروری به طور مؤثر پیشرفت‌ها و دستاوردهای فعلی را در فرآیند EC در تصفیه فاضلاب رنگرزی نشان می‌دهد که می‌تواند بینش‌های جدیدی را در مورد بهبود تصفیه فاضلاب رنگرزی با کاربردهای زیست‌محیطی امیدوارکننده ارائه دهد

چکیده [English]

Dyeing wastewater is one of the most important environmental problems in the textile industry. This wastewater contains harmful pollutants that can damage human health and the environment. Electrocoagulation (EC) is a promising technology for dyeing wastewater treatment. This technology passes an electric current through the wastewater, which generates metal hydroxides that act as coagulants to remove pollutants. This article first introduces the EC system and its operation mechanism, then discusses the components that affect the system's performance in removing dye and chemical oxygen demand. The article also summarizes the studies that have been conducted on the use of this process in the treatment of textile dyeing wastewater. In addition, the economic aspects of the EC process and recommendations for its improvement are provided. Finally, the challenges and prospects of the process are discussed. This article provides an effective overview of the current advances and achievements in the EC process for dyeing wastewater treatment, which provides new insights into improving dyeing wastewater treatment with promising environmental applications.
