TITLE:

USING THE FUNGUS-MICROALGAS SYMBIOSIS IN THE TREATMENT OF OIL INDUSTRY EFFLUENT 

KEY WORDS:

Petroleum; microalgae; filamentous fungus; symbiotic relation and biotechnology

PAGES: 65
BIG AREA: Ciências Exatas e da Terra
AREA: Química
SUMMARY:

The main effluent is the water produced from petroleum, whitch has high amount of and greaase, chemical oxygen demand (COD) and other compounds such as surfactants, nitrogen, phosphates, etc. In tis sense, this qualification verifies the potential of treating the water produced from petroleum, using the treatment combining fungi and microalgae. In this symbiosis, the fungus consumes the photosynthetic carbohydrate provided by the alga as sugars and other nutrients/growth factors, in addition to the hydrocarbons present in the efflent, and in retum, the fungus provides propection for the alga, retaining water and serving as a larger area of capture of mineral nutrients, mainly nitrogenous components and phosphorus present in the effluent. Mcroalgae also capture atmospheric carbon (CO2), allwing complementary environmental gains. It is proposed to stuy the effect of concentration and contaminant (oil) between 100-2000 mg/L, of light intensity (50-200 umaol/(m² s)) and effect of salinity 4-40 g/L, using synthertic effluent and real, using the microalgae Tetradesmus obliquus and the filamentous fungi Aspergillus niger, Pencillium oxalicum and Cunninghamella enchinulata. It is expected to be able to verify the % of removal of the oil and grease content, chemica demand of oxygen, nitrate and phosphates presente in the effluent.
