چکیده

مواد شوینده یکی از پرکاربردترین مواد شیمیایی در زندگی روزمرۀ انسان­هاست. ورود آن­ها به محیط زیست به‌ویژه آب­ها می­تواند باعث بالارفتن COD آب و بروز مشکلات جدی برای موجودات زنده شود. روش­های گوناگونی برای کاهش COD وجود دارد. انعقاد الکتریکی به‌عنوان یک روش الکتروشیمیایی راهکار مناسبی برای کاهش COD است. در این مطالعه به بررسی تأثیر انعقاد الکتریکی برای کاهش COD ناشی از موادشویندۀ لباس‌شویی پرداخته شده‌است. ولتاژ فرایند و تعداد الکترود به‌همراه زمان انعقاد به‌عنوان مشخصه‌های تأثیرگذار بررسی شدند. نتایج نشان داد که حالت 2 الکترود در مدت زمان 40 دقیقه در ولتاژ 15 ولت، منجربه کاهش COD تا 70% می­شود. این مقدار بهینه‌ترین میزان مصرف انرژی ازنظر زمان فرایند و مقدار کاهش شاخصۀ آلودگی بود

چکیده [English]

Detergents are one of the most widely used chemicals in the daily life of humans. Their entry into the environment, especially water, can increase the COD of water and cause serious problems for living organisms. There are different methods to reduce COD. The electrocoagulation process as an electrochemical method is a suitable solution to reduce COD. In this study, the effect of electrocoagulation to reduce COD caused by laundry detergent has been surveyed. Process voltage, the number of electrodes, along with coagulation time as key parameters were investigated as influential parameters. The results showed that the 2-electrode mode reduced COD by 70% in 40 minutes at a voltage of 15 volts. This value was the most optimal energy consumption in terms of process time and the amount of reducing the pollution index.
