- Abstract
Slaughterhouse wastewater is heavily polluted. It contains a high concentration of oil and grease, phosphorus, nitrogen, organic matter and suspended solids. The objective of the research is study the ability of slaughterhouses wastewater treatment by a UASB reactor and define the best hydraulic retention time (HRT). This research focuses on the treatment of slaughterhouse wastewater in Up Flow Anaerobic Sludge Blanket (UASB) reactor In these reactors, the polluted wastewater rises slowly which allows it to form a suspended sludge blanket. Granules of sludge gather on the surface and anaerobic bacteria is activated which feeds on the organic matter which exists in the liquid. The research includes a study of the effect of hydraulic retention time (HRT) on the efficiency of treatment in UASB reactors at a constant temperature of about (30±1)°C. The experiments have illustrated that it is possible to achieve excellent removal efficiency for high concentrations of COD (Chemical Oxygen demand) when the temperature of the wastewater is fixed at (30±1) °C. The removal efficiency fit with HRTs values in UASB reactor, for the following values of HRTs:(6,12,18,24,30,36) hours, the removal efficiencies of COD were:(35.78%, 48.93%, 56.15%, 71.3% , 76.33%, 83.37%) respectively.
