چکیده
|
The dairy farm wastewater (dfw) contains high concentration of organic matter, solids and nutrients# therefore, treatment of this contaminated water is essential# in this study, removal efficiency of chemical oxygen demand (cod) using a sequencing batch reactor (sbr) was studied in a bench-scale set-up# dfw samples were collected with cod of 3100 mg/l# the effect of excess nutrients on biomass growth and cod reduction was investigated, as well as the effect of mixed liquor suspended solids (mlss) concentration on the cod removal# at optimal conditions, including initial organic loading rate (olr) of 2#93 kg cod/m3d, mlss of 4500 mg/l and hydraulic retention time (hrt) of 24 h, 80% of cod removal was observed, approximately#
