description | Instruction and implementation of a new laboratory biological treatmentsystem -unit . The complete removing was achieved after 7 days . The hydraulicwere achieved to reduce the pollution of industrial wastewater of artificialfertilizers company with some inorganic pollutants ( NH4+, NO2-, NO3-ANDSO42- ) and organic ( Biological Oxygen Demand , BOD5 ; urea and TotalSuspended Solids ,TSS ). The modified culture media ,by me , were used tooptimize the specific variables related to this study . Immobilized technique wasused in all units of biological system that consists of Mixo- unit with non discretespaces, Denitrifying and Sulfate reducing units .The mixo-unit was operated by Fed- batch technique of the whole volumemeanwhile the other units by batch technique . In laboratory artificial medium(ND- A ) the primary concentration of ammonium and sulfate were 1300 mg / land 3800 mg / l and reduced to 50% and 45% respectively in Mixoretention timerequired to reduce 500 and 1300 mg / l of ammonium and sulfate respectively infed- batch culture was 40 hr . The retention time of fed- batch became stable at arange of 25 -26 hr in removing the same concentrations and not across theenvironmental limitations of NO2-, NO3- , in addition to reduce the BOD to theallowable concentration . The ammonium , nitrite and nitrate were reduced after 4and 3 days for pretreated and disposed treated wastewater respectively usingMixo- unit and batch technique . Nitrate was removed by concentration of 500 mg /l in denitrifying unit using the modified medium ( O3a – A) . The sulfate wasremoved in modified medium ( C- medium) by concentration of 2129 mg / lduring 3 days using batch technique and anaerobic conditions. |
