CARACTERIZAÇÃO FÍSICO-QUÍMICA DE EFLUENTES DA CARCINICULTURA E SEUS IMPACTOS AO MEIO AMBIENTE

Abstract

Currently, the mangrove regions of the state of Rio Grande do Norte, have suffered great devastation caused by the rapid growth of shrimp farming in which it is operated improperly threatening the ecosystem and the local population. Has become quite a critical situation in terms of water contamination, destruction of native vegetation and reduction of marine species (especially crab). It is true, then, that the degradation of mangroves will result in ecological imbalance, with unpredictable consequences. Among the main culprits in the production cycle for the impacts to the environment, we highlight the effluents generated in step production. This effluent is composed mostly of raw organic decomposition (feed wastes, carcasses of dead animals, waste fecal etc.) as well as chemical agents such as antibiotics and antioxidants. Aiming to reduce problems caused by improper disposal of effluents of these masses, we intend to study and adjust treatment processes of physical, chemical and microbiological tests to reduce the impacts of such effluents, as well as adapting the activity to the legal standards of provision industrial effluents.
