ABSTRACT

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 Paracoccus pantotrophus FMR19 along with the indigenous isolate Bacillus albus 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.Implications: 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.

摘要

家禽废物加工业产生的废水含有几种有机化合物，例如胶原蛋白，明胶，牛血清白蛋白，碳水化合物，必需脂肪酸等。这样就可以建立家禽废物加工业来生产增值产品，例如动物饲料和有机肥料。在禽粪处理过程中，大量的氨氮和有机污染物（例如蛋白质，各种碳水化合物和脂肪物质）被排放到废水中，这造成了许多环境问题。由于当前常规处理方法的缺陷，本研究将与顺序生物反应器系统的发展有关，以有效处理家禽废物加工工业废水。兼性厌氧菌副球菌FMR19与本地分离的芽孢杆菌从澄清的污泥中获得的MN527241被用作混合财团，用于处理家禽废物加工工业废水。混合的微生物联盟使酶（如蛋白酶（247 U / mL）和脂肪酶（28.266 U / mL））具有最大活性，从而在五天内实现了90％的氨氮减少和98％的COD去除。此外，使用气相色谱-质谱（GC-MS），高效液相色谱（HPLC），傅立叶变换红外光谱（FT-IR）和SDS-PAGE对家禽废水进行了确证分析。因此，事实证明，基于生物反应器的连续处理方法在去除禽禽类加工工业废水中的有机污染物方面非常有效。含义：家禽废物处理工业（PWPI）废水中含有大量氨氮和COD，并影响环境。有氧运动床生物膜反应器和上流式厌氧污泥床反应器目前正在实践中，并显示出在较长的保留时间内氨氮和COD的显着降低。因此，需要一种可持续的处理方法，该方法可以在短时间内有效地从废水中去除有机污染物。我们的研究集中在先后顺序生物反应器方法在好氧随后厌氧处理过程中处理PWPI的应用中，并观察到在短时间内有效去除有机污染物。
