%X poultry industries wastewater contains high concentrations of organic matter, suspended solids, fat, nitrogen and phosphorus. its composition and flow generally varies depending on the manufacturing process, plant size, number of slaughtered animals, efficiency the collection of blood and sub-products, water consumption per slaughtered bird and water management in the industrial process. in this regard, the disposal of untreated effluent to the receiving water causes a negative environmental impact. in this study the efficiency of a wastewater treatment system of a zuliana poultry industry (zpi) was evaluated. the parameters chemical oxygen demand (cod), biochemical oxygen demand (bod), total suspended solids (tss), volatile suspended solids (vss), oils and grease (o&g), total kjeldahl nitrogen (tkn), phosphorus (p), temperature (t) and ph, in the affluent and effluent of the treatment system and in each of the units were determined. the treatment system of the zpi is set up of rotary screen, o&g separation tank, activated sludge system (biological reactor and secondary sediment) reactor, secondary sediment, chlorination chamber, in addition the sludge treatment. the results demonstrated that the cod, bod, o&g, tkn, tss and vss were efficiently removed in 89.67, 98.53, 92.55, 97.78, 94.92 and 96.23%, respectively. the p concentrations no shown variations during treatment.
