SUMMARY:

One aspect of basic sanitation is sanitary sewage. About 54,1% of sewage is collected and 49.1% is treated in Brazil. Thus, environmental technologies must be incorporated to remove physical-chemical and biological contaminants so that they return to the environment within standards. Among the technologies: Water quality unit, high-density polyethylene piping aimed at separating solids and oils and Biogill reactor, which has aerobic, anaerobic and anoxic phases associated with a removal efficiency of 90% of biochemical demand for oxygen and nutrients of 80%. Therefore, a treatment plant for electro-electronic effluents was built in the residential located in the city of Barra de São Miguel (AL) to treat them, with the aim of evaluating their treatment efficiency and reuse feasibility. The treated effluent was reused through microsprinkling in the production of aroeira do sertão and ipe purple seedlings, as well as a morphophysiological and statistical comparison of the seedlings in relation to production with drinking water. Among the main results achieved: full compliance with CONAMA resolution nº 430/11; compliance with reuse standards ABNT NBR 13,969/1999, PROSAB, COEMA nº 2/2017 and SES/SMA/SSRH nº 1/2017, except for the turbidity parameter and BOD, requiring improvements in tertiary treatment. Finally, the treated effluent showed better results for the development of the seedlings than the water, and the tukey test (p<0.05) did not obtain a significant difference between the treatments.
