Belém Metropolitan Region has few and incomplete informations about production and destination of sewage sludge, because just little part of the sludge generated in septic tank and collective Sewage Works is throwed away without control in Aurá Sanitary Landfill. Because of this, is usual to throw the sludge in water bodies and in the ground, worsen the problems of pollution/contamination in the urban areas. Therefore, this work has the objective of analyzing the increase of production of sludge and evaluate the impact in the Aurá Sanitary Landfill. The search was developed in Belém Metropolitan Region, composed by Belém, Ananindeua, Benevides, Marituba and Santa Bárbara do Pará. It was divided in 2 stages. In the first stage it was estimated the production of the sludge (brute and drained) of septic tanks and in the collective Sewage Works during 2009 to 2030, and the second one was the availability of an area to disposal in the Aurá Sanitary Landfill. In the period studied, it was verified that by the way of the increase of the content of sludge drainage doesn’t has too many impact in the content of the residence solid waste, the deficiency of the available areas in the Aurá Sanitary Landfill is a problem that has to be solved as soon as possible, otherwise residence solid waste and sewage sludge produced in Belém Metopolitan Region won’t be well disposal, as a matter of fact that the prevision is the fast implicate of the free content of Aurá Sanitary Landfill.

This research presents a comparative study of reactors upflow anaerobic sludge blanket (UASB) and septic tank (ST) in order to investigate the use of these reactors scale single-family home in sewage treatment. The research was conducted in quilombola community near the city of Belém-PA. For this, were used eight UASB reactors (in the form of “Y”) and a septic tank prismatic single camera. The UASB reactors had volume of 0,42 m3, while the septic tank volume of 4,20 m3. Each reactor was installed in a home, with powered exclusively by sewage black (water, feces and urine) come from the toilets of the bathrooms. Was analyzed the technical feasibility of the use of the first replacement in the second, with a view that the ST is widely used in places of Brazil devoid of sewage collecting system. The operations were carried out simultaneously for approximately 90 weeks, being monitored parameters that allowed the analysis of operating stability and performance of each reactor. At the end of the research was observed that the UASB reactors showed performance as satisfactory as or better than that of the ST in the treatment of organic matter and suspended solids. Therefore, was demonstrated the feasibility of application of the UASB reactor used in the treatment of sewage from single-family small rural communities.
