Poultry slaughterhouses discharge very high amount of wastewaters and these wastewaters can be treated successfully at a very low cost using anaerobic treatment. In this study, the Static Granular Bed Reactor (SGBR), a newly developed anaerobic process which is fully anaerobic granule, and another Static Granular Bed Reactor containing both anaerobic granular biomass and non-granular biomass were employed for the treatment of poultry slaughterhouse wastewater. The objective of the use of two reactors having different types of anaerobic biomass is to evaluate whether anaerobic sludge could be used effectively instead of anaerobic granule, which is much more difficult to obtain than the other during the start up period. Average COD removal efficiencies were greater than 95% for both of the reactors. Furthermore, Grau second-order and modified Stover-Kincannon models were successfully used to develop a kinetic model of the experimental data with a high correlation coefficient (R(2)>0.95).
家禽屠宰场排放大量废水，这些废水采用厌氧处理可成功以低成本进行处理。在本研究中，静态颗粒床反应器（SGBR）是一种新开发的完全厌氧颗粒的厌氧工艺，另一个静态颗粒床反应器包含厌氧颗粒生物质和非颗粒生物质，用于处理家禽屠宰场废水。使用具有不同类型厌氧生物质的两个反应器的目的是评估厌氧污泥是否可以有效替代厌氧颗粒，厌氧颗粒在启动期比其他物质更难获得。两个反应器的平均化学需氧量去除效率均大于95%。此外，格劳二阶模型和修正的斯托弗-金坎农模型成功用于开发实验数据的动力学模型，相关系数较高（R²>0.95）。
