Based　on　the　high　turbidity　of　stone　processing　wastewater,　we　introduced　a　new　way　of　wastewater　treatment.　First,　compound　of　a　new　composite　flocculants　(FA-PAC)　was　made　by　from　Fulvic　Acid　and　PAC;　then,　an　orthogonal　experiment　was　designed　and　conducted　to　get　ready　for　the　factors　influence　the　flocculation　and　optimal　flocculation　conditions;　and　then　combined　the　optimal　conditions　for　the　FA-PAC　granite　wastewater　treatment,　SS　of　supernatant　of　treated　wastewater　is　65mg/L,　which　is　meet　the　standard　of　State　Integrated　Wastewater　Discharge　level;　Finally,　FA-PAC　and　PAC-PAM　were　compared,　but　cost　of　the　former　is　only　about　11%　of　the　latter,　which　saved　costs　and　is　eco-friendly.　©　2011　IEEE.
