ABSTRACT

the present study deal with using two species of fungi, Aspergillus Niger, Rhizopus oligosporium, in treatment of wastewater to reduce heavy metals concentrations (Pb, Cd) and some physical and chemical properties from final discharge of Al nassiryacity .Tow group were used in this process ,with tow weight from the mention fungi (1 ,2)gm of each group of fungi with 2 liter of wastewater this group have clone in laboratory in (25◦) extended for 6 days .The result showed that high efficiency in reducing the concentration of( cd and pb) by fungi Aspergillus Niger the percent of removing was 100% more than Rhizopus oligosporium compare with reducing of some environmental parameters.

Keywords: Aspergillus Niger, Rhizopus oligosporium.
