In　this　paper,　the　removal　characteristics　of　five　heavy　metals　(Mn,　Fe,　Zn,　Cr,As)　in　two　urban　wastewater　treatment　plants　called　Aand　B　in　Fuzhou　were　studied.　The　results　showed:　(1)　The　influents　of　these　two　wastewater　treatment　plants　weren＇t　seriously　polluted　by　heavy　metal　heavily　except　for　Mn　and　Fe,　this　may　result　from　the　environmental　background　of　Fuzhou;　(2)　A　takes　A/O　process　as　the　biological　unit,　the　removal　efficiencies　for　these　heavy　metals　of　the　whole　process　ranged　from　7.5%　for　Zn　to　93.1%　for　Fe.　(3)　B　utilizes　CASS　process　for　secondary　treatment,　it　yielded　lower　removal　efficiencies　than　A/O　process　on　the　whole,　ranging　from28.5%forMn　to　88.2%for　Fe　except　Zn;　(4)　BothA　and　Bwere　excellent　in　removing　Fe　while　had　little　removal　efficiency　for　Zn,　thismay　result　fromthe　re-dissolution　of　particulate　Zn;　(5)　the　removal　capacities　for　heavy　metals　of　these　two　wastewater　treatment　plants　were　calculated　respectively,　ranging　from0.03　kg　&bulld-1　to　18.10　kg　&bulld-1.　©　2013　Trade　Science　Inc.　-　INDIA.
