520	3		_aRapid growth of the livestock industry has led to the increase number of slaughterhouses in Malaysia. The wastewater generated from slaughterhouse will contained a large amount of organic and inorganic pollutants which are harmful to the environment. Previous studies had been proved that upflow microaerobic sludge reactor (UMSR) had excellent results in treating piggery water with high ammonium (NH4+-N) and low chemical oxygen demand (COD) to total nitrogen (TN) ratio. In this study, a prototype of UMSR was constructed to treat the slaughterhouse wastewater with high NH4+-N concentration and high COD/TN ratio and to compare its nitrogen removal efficiency with the existing slaughterhouse’s wastewater treatment plant. The acclimation stage of the prototype was 60 days. The reactor was controlled in the microaerobic condition which the dissolved oxygen (DO) was maintained within the range of 0.3 mg/L to 1.0 mg/L and pH value within the range of 7.0-8.0. Influent samples and effluent samples on Day 61, Day 65 and Day 70 were taken from the prototype for analysis. Influent sample and effluent sample were taken from the wastewater treatment plant of Slaughterhouse Kuantan for the comparison. The average percentage removal rate of TN, NH4+-N, COD and biochemical oxygen demand (BOD) of the prototype were 78.28%, 83.57% ,80.59% and 25.30%, respectively. The removal rate of TN, NH4+-N, COD and BOD for existing treatment plant were 19.05% ,18.96%, 82.55% and 9.08%, respectively. In conclusion, the UMSR can perform well in treating high COD/TN ratio wastewater and even had better performance than existing treatment plant.
