Abstract :The objective of the research is to study the ability of baker`s yeast wastewater insert ignore into journalissuearticles values(BYW); treatment by a Up Flow - Anaerobic Sludge Blanket insert ignore into journalissuearticles values(UASB); reactor. The effect of the temperature of BYW on the efficiency of treatment in a UASB was investigated and the experiments showed that it is possible to achieve good removal efficiency of chemical oxygen demand insert ignore into journalissuearticles values(COD); insert ignore into journalissuearticles values( 10200 - 16320 ); mg L -1 when the temperature of BYW is about insert ignore into journalissuearticles values(35± 2 );°C and hydraulic retention time insert ignore into journalissuearticles values(HRT); = 24 h. The removal efficiency fit with temperature value of wastewater in UASB reactor for the following values of temperature of insert ignore into journalissuearticles values( 11 ± 2 ; 16 ± 2 ; 2 6 ± 2 ; 2 6 ± 2 ; 31± 2 ; 35± 2 ); °C. The removal efficiencies of COD were: insert ignore into journalissuearticles values( 36.6 %; 37.9 %; 43 %; 44.2 %; and 48.8%); respectively. The effect of changing the values of HRT on the efficiency removal at a temperature insert ignore into journalissuearticles values(35±2); °C value was investigated. The experiments illustrated that it is possible to achieve good removal efficiency for high concentrations of COD when the temperature of the BYW is fixed at insert ignore into journalissuearticles values(35±2); °C and HRT>=24 h. The removal efficiency fits with HRTs values. For the following values of HRTs: insert ignore into journalissuearticles values(18; 24; 30; 36); h, the removal efficiencies of COD were: insert ignore into journalissuearticles values(32.9%; 48.8%; 48.95%; 51.3%); respectively.
