Background & Objective: Cattle Slaughterhouses are one of the main centers of wastewater producing facilities with high pollution load, which in the absence of proper treatment can cause a lot of environmental pollution. The aim of this study was to determine the effectiveness of Industrial slaughterhouse wastewater treatment plant in the city of Sanandaj in 2012. Method: This is a cross-sectional study which was conducted in the laboratory of faculty of health, university of medical sciences in Sanandaj in the year 2012 for three months. Weekly tests of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solids (TSS) and in total 24 times sampling of input and output for the treatment plant was performed instantly. The experiments were based on the latest proposed method in the book of standard method (the Examination of Water and Wastewater) and at the end, Microsoft EXCEL software was used for data analysis. Results: The average COD, BOD and TSS entering the plant were 2036.69 ± 61, 1216.5 ± 220 and 791.12 ± 147 milligrams per liter and their average output from the plant were 747.71 ± 17, 517.5 ± 8 and 306.51 ± 8 milligrams per liter and the total average of removal efficiency for each of these parameters were 63.29 ± 3 percent, 57.45 ± 2 percent and 61.25 ± 5 percentage respectively. Conclusion: The quality of output effluent from treatment plant of cattle slaughterhouse in Sanandaj, in almost all months was not according to effluent disposal standards and generally, the efficiency of this treatment plant is not desirable in removal of contaminants. Therefore, its efficiency should be improved by using appropriate methods.
