In this study, a sequential batch reactor (SBR) with different types of fibers was employed for the treatment of poultry slaughterhouse wastewater. Three types of fibers, namely, juite fiber (JF), bio-fringe fiber (BF), and siliconised conjugated polyester fiber (SCPF), were used. Four SBR experiments were conducted, using the fibers in different reactors, while the fourth reactor used a combination of these fibers. The treatment efficiency of the different reactors with and without fibers on biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammonia-nitrogen (NH₃-N), phosphorus (P), nitrite (NO₂), nitrate (NO₃), total suspended solids (TSS), and oil-grease were evaluated. The removal efficiency for the reactors with fibers was higher than that of the reactor without fibers for all pollutants. The treated effluent had 40 mg/L BOD₅ and 45 mg/L COD with an average removal efficiency of 96% and 93%, respectively, which meet the discharge limits stated in the Environmental Quality Act in Malaysia.
在这项研究中，采用了一种带有不同类型纤维的序批式反应器（SBR）来处理家禽屠宰废水。使用了三种纤维，即剑麻纤维（JF）、生物 fringe 纤维（BF）和硅化共轭聚酯纤维（SCPF）。进行了四个 SBR 实验，分别在不同的反应器中使用纤维，而第四个反应器则使用这些纤维的组合。评估了不同带有和不带有纤维的反应器对生化需氧量（BOD）、化学需氧量（COD）、氨氮（NH₃-N）、磷（P）、亚硝酸盐（NO₂）、硝酸盐（NO₃）、总悬浮固体（TSS）和油-油脂的处理效率。对于所有污染物，带有纤维的反应器的去除效率均高于没有纤维的反应器。处理后的废水 BOD₅为 40mg/L，COD 为 45mg/L，平均去除率分别为 96%和 93%，符合马来西亚《环境质量法》规定的排放限值。
