ANÁLISE DOS PARÂMETROS FÍSICOS-QUÍMICOS DO EFLUENTE SANITÁRIO: Qualidade do resíduo após tratamento em unidade de eletrólise para uso em condomínios

Abstract

This research provides an interesting alternative to condominiums, hotels and resorts on the shores of Lake Furnas-MG, in terms of conventional sewage treatment, suggesting the use of a sewage treatment unit by electrolysis. The research analyzed the post-treatment quality of physical-chemical parameters (D.B.O, D.Q.O, SS, Total oils and greases and PH) in relation to the requirements imposed by resolution N° 430, of May 13, 2011. To achieve the desired objectives, the history of laboratory results of the last seven years of sanitary effluent entering and leaving an electrolysis treatment unit were divided, reorganized, compiled, analyzed and compared with the present resolution nº 430. The results were satisfactory in relation to the quality of the effluent sanitary, where it was possible to verify that the electrolysis treatment unit fits all the physical-chemical parameters imposed by the resolution n° 430, thus enabling the disposal of the sanitary effluent after treatment in rivers or lakes.
