دراسة إمكانية إزالة الهيدروكربونات النفطية و بعض الملوثات في مياه المخلفات النفطية لمصفى النجف : 1-باستعمال الفطريات المفردة

Abstract EN

The study included two axes the first is isolate and diagnose fungal oil waste water refinery resulting from oil in Najaf refining and the surrounding soils.Five species isolates belong to(3)genera included (22) isolation of fungus Aspergillus niger and (72) the isolation of fungus Aspergillus terreus and (8) the isolation of the fungus Aspergillus versicoler and (102) isolation of fungus Penicillium sp.

and (2)isolate yeast Rhodotorula sp.

The total isolates (206) isolated from oil-contaminated soils, either from Najaf refinery water has been isolated (3) isolation of the fungus A.

niger and (8) the isolation of yeast.

Rhodotorula sp The total isolates (11) isolation, was chosen three types of fungi isolated with the most frequency which Penicillium sp.

By (49.51%) and A.

niger by 10.67% and A.

terreus by 34.95% and Axis two study the efficiency of fungus three types choose for exposel to Najaf refinery wastewater for 7 days agreat removal percent occure for hydrocarbons with Penicillium sp.

As consumed 55 % of the weight of the existing total hydrocarbon in media and the least efficient A.

niger as consumed (41%) of it.

Showed Penicillium sp.

Efficiency in reducing the conductivity, salinity and total TDS and total hardness and calcium hardness, magnesium hardness and sulfate showed A.

niger fungus higher efficiency under study to reduce nitrate and nitrite, phosphate and equal efficiency with Penicillium sp in the alkalinity reduce.
