چکیده مقاله :

زمینه و هدف: با توجه به قوانین سختگیرانه زیست محیطی و مشکل کمبود آب در سال های اخیر تصفیه پساب خروجی از صنایع جهت استفاده مجدد ضروری است. پساب صنعت قارچ به دلیل اسفاده از انواع کودها و سموم، مواد ضدعفونی کننده و شوینده ها حاوی آلاینده های آلی و معدنی مختلفی است که پارامترهای آلایندگی از قبیل دترجنت، کدورت، BOD و CODدر آن بالاتر از حد مجاز استاندارد می باشد. در این تحقیق تصفیه پساب کارخانه قارچ جهت استفاده مجدد در بخش پرورش و کمپوست سازی بررسی شده است.روش بررسی: در این پژوهش که در آزمایشگاه شرکت کشت و صنعت ملارد (سال 1399) انجام شد جهت تصفیه پساب و حذف پارامترهای BOD، COD، کدورت و دترجنت روش های انعقاد الکتریکی و شیمیایی مورد استفاده قرار گرفت. روش انعقاد الکتریکی در اختلاف پتانسیل 10، 20 و 30 ولت و زمان های 15، 30، 45، 60 و 75 دقیقه توسط الکترودهای آهن و آلومینیوم انجام شد. در روش انعقاد شیمیایی تاثیر دو منعقده کننده پلی آلومینیوم کلراید و سولفات آلومینیوم در حضور کمک منعقده کننده پلی الکترولیت آنیونی بر روی تصفیه پساب بررسی شد.یافته‌ها: در روش انعقاد الکتریکی در اختلاف پتانسیل 30 ولت به مدت 60 دقیقه، راندمان حذف COD و BOD به ترتیب 1/59 و 46 درصد حاصل شد. در روش انعقاد شیمیایی با میزان دوز منعقد کننده 75 میلی گرم در هر لیتر از پساب و pH 6 بیشترین راندمان حذف برای COD، BOD، کدورت و دترجنت به ترتیب 6/61، 6/47، 1/82 و 5/75 درصد به دست آمد.بحث و نتیجه‌گیری: نتایج نشان داد راندمان حذف پارامترهای BOD، COD، دترجنت و کدورت توسط انعقاد شیمیایی کمی بالاتر از انعقاد الکتریکی است. همچنین در روش انعقاد شیمیایی منعقد کننده پلی آلومینیوم کلراید هم از سولفات آلومینیوم و هم از ترکیب هر دو منعقد کننده عملکرد بهتری دارد.

چکیده انگلیسی:

Background and Objective: Due to strict environmental laws and the problem of water shortage in recent years, industrial wastewater treatment is necessary for reuse. Mushroom industry effluents due to the use of fertilizers and pesticides, sanitizers and detergents contain various organic and inorganic pollutants, in which the pollution parameters such as detergent, turbidity, BOD and COD are higher than the standard limits. In this research, the effluent treatment of the mushroom factory has been investigated for reuse in for reuse in mushroom cultivation and composting.Material and Methodology: In this study, electrical and chemical coagulation methods were used to treat the wastewater and remove the parameters of BOD, COD, turbidity and detergent. The electrocoagulation method was performed at potential differences of 10, 20 and 30 volts and at times of 15, 30, 45, 60 and 75 minutes with iron and aluminum electrodes. In the chemical coagulation method, the effect of two coagulants, poly aluminum chloride and aluminum sulfate, in the presence of anionic polyelectrolyte coagulant on the effluent treatment was investigated.Finding: In the electrocoagulation method, at a potential difference of 30 volts for 60 minutes, the removal efficiencies of COD and BOD were 59.1% and 46%, respectively. In chemical coagulation method with coagulant dose of 75 mg/l at pH 6, the highest removal efficiencies for COD, BOD, turbidity and detergent were obtained 61.6, 47.6, 82.1 and 75.5%, respectively.Discussion & Conclusion:  The results showed that the removal efficiency of BOD, COD, detergent and turbidity parameters by chemical coagulation is slightly higher than electrocoagulation method. Also, in the chemical coagulation method, poly aluminum chloride coagulant has better performance than both aluminum sulfate and the combination of two coagulants.
