Chitosan, a flocculant, is used to treat organic wastewater containing Cu2+, COD 1×105mg/L andturbidity 500 ～ 1 000 mg/ L.The range of suitable pH is f rom 5.5 to 6.5.The amount of chitosan varies with COD and the turbidity of liquid waste.The results of decreasing turbidity and Cu2+ are satisfactory.The mechanismof chitosan flocculating organic waste water is electrostatic gravitational force and chitosan is a positive ionicflocculating agent.
Key words： chitosan; organic waste water; flocculant
