“…LO MONACO et al (2011) observed an increase in the ST concentration in the affluent of wastewater from swine breeding due to the contribution of solids from the coffee straw used as filtering material. The same result was observed by Brandão et al (2000), who found the increase of solids in swine breeding wastewater passed through organic filter consisting of sawdust and sugar cane bagasse.…”

This study aimed to evaluate the effect of Moringa oleifera Lam extract on the removal of total solids (TS), total suspended solids (TSS) and chemical oxygen demand (COD), in different filter media for treating wastewater of dairy cattle breeding (DCW). The moringa seed extract was obtained by grinding 50 g of seeds in one liter of distilled water and, after passing the solution through a quantitative paper filter of 25 microns, 60 mL of the extract were added to wastewater from cattle breeding before the filtration process in organic filters made of thin coal, bamboo leaves, eucalyptus leaves, gliricidia branches and sawdust. This was followed by the completely randomized experimental design, adopting a factorial of 5 x 2. Aliquots of filtered effluent were collected and the total solids (TS) concentrations, total suspended solids (TSS) and chemical oxygen demand (COD) were determined. It was found that the increase in the efficiency of removal of COD and total solids can be attributed to the coagulating power of the moringa seed extract, wherein the filter medium with bamboo leaves presented the best performance, showing potential for use as alternative filter material in the primary treatment of DCW.

“…Regarding the ARS, we used the progression data until the fifth day, due to the high concentration of nitrogen and nitrogen rapid beginning phase. For comparative purposes, BRANDÃO et al (2000) found a concentration of 936 mg L -1 of nitrogen in ARS, being this concentration dependent on the type of animal feed (ORRICO JR. et al, 2010), while the typical concentration in sanitary sewage is about 45 mg L -1 . The confirmation of settlement in late purge data of BOD progression was evident because higher correlation coefficients and smaller errors of estimation for the fitted equations were obtained.…”

Studies on the effects of temperature and time of incubation of wastewater samples for the estimation of biodegradable organic matter through the biochemical oxygen demand (BOD), that nowadays are rare, considering that the results of the classic study of STREETER & PHELPS (1925) have been accepted as standard. However, there are still questions how could be possible to reduce the incubation time; whether the coefficient of temperature (θ) varies with the temperature and with the type of wastewater and if it approaches 1.047. Aiming the elucidation of these questions, wastewater samples of dairy, swine and sewage treated in septic tanks were incubated at temperatures of 20, 30 and 35 °C, respectively for 5, 3.16 and 2.5 days. From the parameter of deoxygenation coefficient at 20 °C (k 20 ), θ 30 and θ 35 were calculated. The results indicated that θ values changes with the type of wastewater, however does not vary in the temperature range between 30 and 35 °C, and that the use of 1.047 value did not implied significant differences in obtaining k in a determined T temperature. Thus, it is observed that the value of θ can be used to estimate the required incubation time of the samples at different temperatures. C, e que o emprego do valor de 1,047 não implicou diferenças significativas na obtenção de k para uma determinada temperatura T. Assim, observa-se que esse valor de θ pode ser empregado caso se queira estimar o tempo necessário de incubação das amostras em diferentes temperaturas. KEYWORDS

“…Bley Junior (1997) estima que uma granja com 300 matrizes, em ciclo completo, produz diariamente um volume de 60m3 de águas residuárias, que contém uma tonelada de sólidos e que os suínos excretam 30% de sua alimentação em estado praticamente intacto. Segundo Brandão et al (1999), cada suíno produz em média 10 litros de dejetos líquidos por dia. A quantidade total de dejetos produzidos pelos suínos varia com o estádio de desenvolvimento do animal, de 4,9 a 8,5% de seu peso, por dia, considerando a faixa dos 15 aos 100kg de peso vivo.…”

The disposal of residuary water from swine production in soil is a recycling activity that makes possible the use of the hydric potential and the nutrients present in these effluents. The swine dejections have great fertilizing potential, being able to favor the producer that will reduce the costs with fertilizer application, as the environment, since these dejections are highly pollutant when launched directly in rivers and lakes. The pollutant potential of the swine dejections is very superior to other animal species and its use as organic fertilizing can also contribute for the contamination of the hydric resources and the soil if were applied amounts superior to the capacity of soil and plants in absorbing the nutrients present in these residues. The nitrogen is one of the main nutrients present in swine dejections. The mineralization of nitrogen is influenced, among others factors, for the temperature and the water content in the medium. Although many attempts for the development of indices that make possible to esteem as a simple and efficient form the capacity of organic nitrogen mineralization in soil, success due has not been gotten by the complexity of factors that affect the dynamics of this element. Although advantages of the use of swine dejections as fertilizing are evidenced, is reduce the knowledge about the mineralization of organic nitrogen present in this dejection. In this context, this work deals with the use of swine dejections as an alternative for fertilization in soil with emphasis in the mineralization of organic nitrogen.
