چکیده مقاله :
زمینه و هدف: فسفر یکی از مهم ترین آلاینده های محیط های آبی می باشد. آلودگی فسفر در منابع آب های سطحی و زیرزمینی از استفاده مفرط کود در زمین های کشاورزی کنترل نشده و تخلیه فاضلاب های تصفیه نشده نشات می گیرد. تخلیه این عنصر در محیط اثرات بهداشتی بسیار زیادی دارد. این پژوهش با هدف بررسی کارایی فرایند اکسیداسیون فنتون در کاهش فسفر از محلول آبی انجام گرفت. روش بررسی: این تحقیق حاصل یک مطالعه تجربی در مقیاس آزمایشگاهی می باشد. دراین مطالعه تاثیر پارامترهای متغیر شاملpH، غلظتFe+2، غلظت H2O2، زمان تماس و غلظت اولیه فسفر در حذف فسفر به وسیله فرآیند فنتون از محلول آبی مورد بررسی قرار گرفت. یافتهها: نتایج به دست آمده نشان داد که فرآیند فنتون قادر به حذف 97 درصد فسفر می باشد به گونه ای که بیشترین درصد حذف فسفردر نسبت غلظتH2O2 / Fe2+=mg/l 1000/2200، زمان تماس60 دقیقه و 5/3 pH= مشاهده گردید. نتایج آزمون آماری SPSS نشان داد که میانگین غلظت در تمامی متغییر ها قبل و بعد از انجام فرایند اختلاف معنی داری حذف داشت (05/0P<). بحث و نتیجهگیری: نتایج این پژوهش کارایی مطلوبی در حذف فسفر به وسیله فنتون در تصفیه آب و کنترل آلاینده نشان داد. فرایند فنتون یک فرآیند موثر در حذف مواد آلی مانند فسفر از آب از لحاظ میزان راندمان حذف و هزینه مقرون به صرفه تر در مقایسه با دیگر فرآیند های حذف این آلاینده ها می باشد. در ضمن جهت دست یابی به روش های ترکیبی کامل تر و بهتر توصیه می شود در سایر مطالعات راندمان حذف به وسیله این فرآیند را با استفاده از ترکیب با اکسیدان های دیگری مانند تابش فرابنفش و ... ارتقاء داد.
Background and Objective: phosphorus considered among the major pollutants in water environments. Phosphoris contamination in surface water and groundwater resources originates mainly from the excessive use of fertilizers and uncontrolled land discharges of untreated wastewater. Discharge of it into the enviroment causes many negative health impact.The aim of this study was to investigate the efficiency of Fenton’s advanced oxidation process (H2O2/Fe+2) in the phosphorus removal from aqueous solutions. Method: This is an experimental study which is carried out in laboratory scale. In this study, the effect of the important operational variables including pH,Fe+2 dosage, H2O2 dosage, initial phosphorconcentration,and Contact time were evaluated on the phosphate removal from Aqueous Solution by Fenton has been investigated. Findings:The results showed that this method has the ability to remove phosphorus from aqueous solutions to less than standard level WHO (≤1mg/l).pH , ratio H2O2 / Fe+2 and Contact time have direct effect and initial phosphor concentration has reverse effect of phosphor removal. The results showed that the Fenton process, can reach respectively 97% phosphor removal. So that optimum condition of the phosphorus removal is in the Ratio H2O2 / Fe2+ dosage = 2200 /1000 mg/l, contact time of 60 min, pH = 3.5 in initial phosphor Concentration in 100mg /L. SPSS statistical test showed that the mean concentration in the before and after doing all process, there were significant differences ( P ≤ 0.05 ). Discussion and Conclusion: Results show, the efficient removal of phosphate using Fenton process is desirable in the water treatment and pollution control.The results of the study is consistent with similar cases by other researchers. Key words: Removal, Phosphor, Fenton Process, Aqueous Solution.
