This study evaluated the efficiency of a constructed wetland system (CWS) in removing total coliforms (TC) and thermotolerant coliforms (ThC) of swine wastewater, as a complementary treatment to an anaerobic system. At Stage 1, the experimental system was combined using a vertical flow constructed wetland system (VFCWS) cultivated with Tifton 85 grass in series with a horizontal subsurface flow constructed wetland system (HFCWS1) cultivated with Taboa. In HFCWS1, the hydraulic detention times (HDT) were 4.7, 3.1 and 2.3 days and the surface application rates (SAR) were 294, 319 and 397 kg ha-1 d-1 of COD, in Phases I, II and III, respectively. At Stage 2, the experimental system was combined using a horizontal subsurface flow constructed wetland system (HFCWS2) cultivated with Tifton 85 grass, HDT were 6.1, 2.0 and 0.5 days and the SAR were 850, 656 and 6.34 kg ha-1 d-1 of COD, in Phases I, II and III, respectively. In Stage 1, it was verified that the VFCWS was more efficient in coliform removal when compared to HFCWS1. When only HFCWS were compared, coliform removal in Stage 1 was between 1 and 2 log units in HFCWS1. In the stage 2, the HFCWS2 was more limited, with the highest removal efficiencies during Phase I of 1.6 and 0.8 log units for TC and ThC, respectively. In general, the association resulted in efficiencies that ranged from 96.4 to 99.0% for TC, 94.2 and 97.6% for ThC, equivalent to the average removal of 1.2 to 2 log units, considered satisfactory.

“…Estudos com outros resíduos agroindustriais obtiveram resultados semelhantes. Amorim (2015) que em estudo análogo, obteve 80 % de eficiência de remoção da DQO da manipueira em frascos reatores com mesma concentração de matéria orgânica sendo tratada por biomassa anaeróbia que a utilizada no presente estudo e Cremonez et al (2016) ao estudar a digestão de um polímero de fécula de mandioca em biodigestores em escala laboratorial obtiveram 79 % de remoção de DQO.…”

As Ciências estão globalizadas, englobam, atualmente, diversos campos em termos de pesquisas tecnológicas. Com o crescimento populacional e a demanda por alimentos tem contribuído para o aumento da poluição, por meio de problemas como assoreamento, drenagem, erosão e, a contaminação das águas pelos defensivos agrícolas. Tais fatos, podem ser minimizados por meio de estudos e tecnologias que visem acompanhar as alterações do meio ambiente pela ação antrópica. Portanto, para garantir a sustentabilidade do planeta é imprescindível o cuidado com o meio ambiente. Este volume dedicado à diversas áreas de conhecimento trazem artigos alinhados com a Engenharia Sanitária e Ambiental Tecnologias para a Sustentabilidade. A sustentabilidade do planeta é possível devido o aprimoramento constante, com base em novos conhecimentos científicos.Aos autores dos diversos capítulos, pela dedicação e esforços sem limites, que viabilizaram esta obra que retrata os recentes avanços científicos e tecnológicos, os agradecimentos do Organizador e da Atena Editora.Por fim, esperamos que este livro possa colaborar e instigar mais estudantes e pesquisadores na constante busca de novas tecnologias para a Engenharia Sanitária e Ambiental, assim, garantir perspectivas de solução de problemas de poluição dos solos, rios, entre outros e, assim garantir para as atuais e futuras gerações a sustentabilidade.

“…There are numerous plant species active and suitable for cultivation in wastewater treatment systems, and those occurring naturally in the region, which also tolerate the anoxic conditions of these systems, are the most wanted (Amorim et al, 2015). The aquatic macrophytes present a relatively fast life cycle and reproduce both sexually and asexually, allowing a greater success in growth and propagation.…”

Seasonal performance of aquatic macrophytes in improving physicochemical parameters of swine wastewater

2020

Swine wastewaters (SW) present organic load and nutrient content, what have caused degradation of water quality in many watercourses. Thus, the aquatic macrophytes represent an alternative for the depollution of these wastewaters, due to the high recovery power. The aim of this study was to evaluate the performance of the Eichhornia crassipes (Mart.) Solms, Pistia stratiotes L. and Salvinia auriculata Aubl. in improving the physicochemical targets of SW, as well as to quantify the total ammoniacal nitrogen (NH4+) and total phosphorus (total P) in the plant tissue of the macrophytes and the dry matter biomass (DMB) in two seasons of the year (spring and winter). The experiment was designed in a randomized block design, with 4 treatments (T) with 4 replicates: T1 = Control (without plants); T2 = E. crassipes; T3 = P. stratiotes; and T4 = S. auriculata, submitted to a SW diluted in 50% water. The monitoring is done in tanks during a period of 30 days of each season. Electrical conductivity (EC), dissolved oxygen (DO), turbidity, NH4+ and dissolved phosphorus (P) were analyzed in the SW. In the plants, the contents of NH4+, total P and DMB were determined. It was verified that, in the spring, the plants showed higher production of DMB and a more significant reduction of EC, NH4+ and P, when compared to the plants managed in the SW in the winter. E. crassipes was more efficient at removing P (39%) and total NH4+ (80.2%), and EC reducing (92%) of SW and DMB production in the spring. The results demonstrated that the NH4+ uptake by E. crassipes contributed to a considerable removal of NH4+ and P from SW.
