Resumo: | In the civil construction sector, the construction site represents a temporary structure that is capable of generating a large environmental liability, depending on the size of the work, since this sector can be considered as an activity that affects the environment with generation of various types of waste, including sanitary sewage. The great question is how to treat this effluent in an efficient and inexpensive way so that a noble destination can be given to the treated effluent. In this case, its use in the application of the composition of the mortar or of the concrete produced in the work itself. In this study, a treatment known as Bioremediation with the use of aquatic plants, the macrophyte Eichornnia crassipes and the use of the biofilm was tested, besides a physical filter. In order to ensure effective treatment, this project was concerned with complying with current standards such as DNER-EM034-97 - Water for Mortar and Concrete and for the standard of water bodies and the standard for launching Resolution CONAMA 430 (2011) of the Ministry of the Environment, which provides for the conditions and standards for the discharge of effluents, complements and amends Resolution 357 (2005). The system was set up in a sewage treatment plant of the Sergipe Sanitation Company - DESO that performs the monitored treatment of domestic sewage generated by the neighborhood of Orlando Dantas in the city of Aracaju - SE. After preparation of a mini-station for the capture of part of the effluent (bypass) to carry out the research. The stabilization of the biotreatment was waited for the withdrawal of some samples and later laboratory analysis. Different models of biotreatment were tested until a methodology adequate to the proposed objective was achieved. With the report of the analysis of the sample issued by the Technological and Research Institute of the State of Sergipe (ITEC), it was concluded that the treatment proved to be effective given the conditions established by the standard requirement. |
