مقارنة خصائص مياه الصرف الصحي المعالجة في ثلاث محطات في محافظات الفرات الأوسط و مقارنتها بالمعايير القياسية

Abstract

The determinants of environmental pollution of the treated wastewater has been studied for three treatment plants in the Middle Euphrates, Kerbala - Najaf - and Babylon during the period (01/01/2010) to (01/07/2010). The results were compared with the standard delimiters included determinants BOD, COD, Cl ,SO4, NH3 , NO3 ,PO4 , TSS, grease and oils. Was noted from the results that the Karbala station does not work very efficiently since the BOD , COD , , SO4, NH3, NO3, PO4, TSS, grease and oil all off limits except NO3 and Cl. The station of Najaf work well because the BOD , COD, Cl , NO3 , TSS within the permissible limits. Except, NH3, PO4 , SO4, grease and oil are outside the border. While Babylon station work more efficiently than Kerbala and Najaf, only NH3, SO4, grease and oilare all off limits.
