Self-purification is the ability of the water bodies have to recover naturally, i.e. without intervention, after receiving some type of organic load, but this capacity is limited and influenced by a few factors. So, this research aims to study the self-purification capacity of Limoeiro Stream (class 4), located in the city of Presidente Prudente - SP, after the introduction of a source of pollution, which in this case is the release of treated effluent. The mathematical modeling used is the Streeter & Phelps (1925), which depends on the quantification of limnological and hydrological variables, which was held in 5 sections. The results showed that the stream has capacity to support the treated sewage which it receives, that is, it can recover gradually its earlier features the introduction of the organic load. |
