Cattle slaughterhouses are potential causes the environmental impacts, as it require a large volume of water in meat processing, generate large effluents amount, and promote the Cerrado deforestation for animal husbandry. Therefore, we aim was carried out to assess the effects of the soil application of a green line wastewater from a cattle slaughterhouse in the Brachiaria brizantha growth. The M1 and M2 managements did not contain wastewater of slaughterhouse. The wastewater from the 3 rd stabilization pond (M3 to M5), from reception box (M6 to M8), and manure (M9 and M10) were used in the biofertigation managements. The physical-chemical indicators levels did not show significant differences (p < 0.05) before soil preparation and after managements. However, biofertigation in the Cerrado soil can provide a mitigation of the leaching of fine soil particles and cations. In addition, maximum nitrogen dose of wastewater provided a higher leaf biomass productivity than commercial nitrogen. Thus, the fertigation with wastewater can reduce the use of water bodies to crops irrigation and the incorporation of new areas with native vegetation to the agricultural production systems.

“…La concentración de nitrógeno obtenida luego del tratamiento fisicoquímico corresponde a compuestos orgánicos solubles e inertes. Louvet et al, (2013) identificaron proteínas y aminoácidos que contribuyen al nitrógeno del efluente de un matadero de reses tratado en un SBR, indicando que entre los compuestos identificados por fluorescencia están proteínas como la albúmina, la metaloporfirina y la globulina, y aminoácidos como la tirosina, y el triptófano.…”

Los efluentes provenientes del sacrificio de cerdos son una fuente de contaminación debido a las altas concentraciones de materia orgánica, nitrógeno, fósforo, grasas, sólidos totales y coliformes fecales. En esta investigación se evaluó la efectividad del quitosano como coagulante en el postratamiento de efluentes porcícolas provenientes de un reactor discontinuo secuencial, con el fin de remover las fracciones no biodegradables remanentes del proceso biológico. El tratamiento terciario consistió en la coagulación, floculación y sedimentación. Se caracterizó el efluente tratado biológicamente mediante los siguientes parámetros: pH, DQO, turbidez, color, sólidos totales (ST), nitrógeno total Kjeldahl (NTK), nitrito, nitrato, fosforo total (PT) y alcalinidad total (AT). El tratamiento fisicoquímico se llevó a cabo mediante el uso de la prueba de Jarra a través de corridas exploratorias con dosis entre 50 y 800 mg/L de quitosano disuelto en ácido acético. Se comparó la efectividad del quitosano (700 mg/l) con sulfato de aluminio (430mg/l) y poliacrilamida (90 mg/l), los cuales son utilizados como coagulantes de uso convencional en el tratamiento de aguas residuales. El experimento se condujo mediante un diseño completamente al azar con un total de tres tratamientos (quitosano, sulfato de aluminio y poliacrilamida) y tres repeticiones cada uno. La dosis de quitosano (700 mg/l) permitió obtener porcentajes de reducción de turbidez de 83.1%, color de 64.7%, DQO de 84.6%, y 78.2% de NT para valores iniciales de 15.6 NTU, 26 UC Pt-Co, 865 mg DQO/L y 89 mg NT/L. Se encontraron diferencias significativas (P≤0.05) entre la dosis quitosano (700 mg/l) y los coagulantes convencionales (430 mg/l de sulfato de aluminio y 90 mg/l de poliacrilamida) en la reducción de NT, siendo el tratamiento con quitosano el coagulante con las mayores eficiencias de reducción. El tratamiento con quitosano con una dosis de 700 mg/l representó una opción viable para el tratamiento terciario de los efluentes proveniente del proceso de sacrificio de cerdos tratados biológicamente.

“…Up until quite recently, research activities were mainly focused on offline spectral acquisition (Thomas et al 1993). A clear example of this was the monitoring of slaughterhouse wastewater biodegradation in a lab-scale SBR using offline UV-Vis spectra, relating A416 (416 nm absorbance) with COD during wastewater biodegradation (Louvet et al 2013). Also, TOC estimation in a WWTP using offline UV-Vis spectra was performed by Lourenço et al (2008) through the use of PLS regression models.…”

Biological processes based on aerobic and anaerobic technologies have been continuously developed to wastewater treatment and are currently routinely employed to reduce the contaminants discharge levels in the environment. However, most methodologies commonly applied for monitoring key parameters are labor intensive, time-consuming and just provide a snapshot of the process. Thus, spectroscopy applications in biological processes are, nowadays, considered a rapid and effective alternative technology for real-time monitoring though still lacking implementation in full-scale plants. In this review, the application of spectroscopic techniques to aerobic and anaerobic systems is addressed focusing on UV-Vis, infrared, and fluorescence spectroscopy. Furthermore, chemometric techniques, valuable tools to extract the relevant data, are also referred. To that effect, a detailed analysis is performed for aerobic and anaerobic systems to summarize the findings that have been obtained since 2000. Future prospects for the application of spectroscopic techniques in biological wastewater treatment processes are further discussed.
