The effluent generated from poultry waste processing industries contains several organic compounds such as collagen, gelatin, bovine serum albumin, carbohydrates, essential fatty acids, and so forth. This enabled the establishment of poultry waste processing industries to produce value-added products such as animal feed and organic fertilizers. During poultry waste processing, huge amounts of ammoniacal nitrogen and organic pollutants such as proteins, various carbohydrates, and fatty materials are discharged into the effluent stream which contributes to several environmental issues. Because of the shortcomings of the current conventional treatment, the present study is about with the development of a sequential bioreactor system for the effective treatment of poultry waste processing industrial effluent. Facultative anaerobe FMR19 along with the indigenous isolate MN527241 obtained from clarifying sludge was used as mixed consortia for the treatment of poultry waste processing industrial effluent. The mixed microbial consortia resulted in the maximum activity of enzymes such as protease (247 U/mL) and lipase (28.266 U/mL) thereby achieving 90% of ammoniacal nitrogen reduction and 98% of COD removal within five days. Further, the confirmatory analysis of poultry effluent treatment was carried out using gas chromatography-mass spectroscopy (GC-MS), High-Performance Liquid Chromatography (HPLC), Fourier Transform Infrared Spectroscopy (FT-IR), and SDS-PAGE. Hence, the sequential bioreactor-based treatment approach has proved to be highly effective in removal of organic pollutants in the poultry waste processing industrial effluent.: The poultry waste processing industrial (PWPI) effluent contains huge ammoniacal nitrogen and COD and affects the environment. Aerobic moving bed biofilm reactor and up-flow anaerobic sludge blanket reactor are in current practice and shows considerable reduction in the ammoniacal nitrogen and COD in long retention time. Therefore, there is a need of sustainable treatment process that could effectively remove the organic pollutants from the effluent in short duration. Our study focused on the application of sequential bioreactor approach for the treatment of PWPI using aerobic followed by anaerobic treatment process and observed efficient organic pollutants removal in short duration.
家禽废物处理工业产生的废水含有多种有机化合物，如胶原蛋白、明胶、牛血清白蛋白、碳水化合物、必需脂肪酸等。这使得家禽废物处理工业能够生产增值产品，如动物饲料和有机肥料。在处理家禽废物的过程中，大量的氨氮和有机污染物，如蛋白质、各种碳水化合物和脂肪物质，被排放到废水中，这导致了一些环境问题。由于目前常规处理方法的缺点，本研究开发了一种顺序生物反应器系统，用于有效处理家禽废物处理工业废水。好氧兼性厌氧菌 FMR19 与从澄清污泥中获得的本土分离株 MN527241 一起用作处理家禽废物处理工业废水的混合菌群。混合微生物群落使蛋白酶（247 U/mL）和脂肪酶（28.266 U/mL）的最大活性，从而在五天内实现 90%的氨氮减少和 98%的 COD 去除。此外，还使用气相色谱-质谱联用（GC-MS）、高效液相色谱（HPLC）、傅里叶变换红外光谱（FT-IR）和 SDS-PAGE 对家禽废水处理进行了确证分析。因此，基于顺序生物反应器的处理方法已被证明在去除家禽废物处理工业废水中的有机污染物方面非常有效。：家禽废物处理工业（PWPI）废水含有大量的氨氮和 COD，会影响环境。好氧移动床生物膜反应器和上流式厌氧污泥床反应器是目前的实际应用方法，在较长的保留时间内可以显著减少氨氮和 COD。因此，需要一种可持续的处理工艺，能够在短时间内有效地从废水中去除有机污染物。我们的研究重点是应用顺序生物反应器方法处理 PWPI，采用好氧 followed by 厌氧处理工艺，并观察到在短时间内有效去除有机污染物。
